This is really awesome. PHP doesn't allow this as a inbuilt func, but to me its look generic enuf to be included in pHp6

Comment by Joe Li on: Improve MySQL Insert Performance

Joe Li — Wed, 08 Jul 2009 05:20:28 +0100

Two reminders: 1. To execute LOAD DATA INFILE queries, the user must have the FILE privilege. It may be a concern as many website hosting provider does not allow to grant this to user. 2. Transaction: LOAD DATA INFILE outperforms at record insertion, but it may be a problem for data integrity. I am not sure if LOCK/UNLOCK TABLES queries are still required for such action. Feel free to share and discuss.

Comment by Kevin on: Create daemons in PHP

Kevin — Tue, 07 Jul 2009 14:30:49 +0100

Typically you would configure a deamon to run at server boot, and have it accept jobs while it's running. If you want to control a daemon's start / stop you typically would do that with a script inside /etc/init.d (os dependent, for some OSes, System_Daemon can generate such a script for you) So, yes in theory you could then use a PHP script to control run the init.d script and control your daemon process. But I'd hardly recommend it because of - bad practice - security risks involved

Hey, Thanks for this great article. I think about using your daemon in my web application. This might be a stupid question, but since the daemon can only be started out of command line, will it be possible, to do a shell_exec to start the daemon out of a web application? Thanks in advance dulig

It seems through some trials and a lot of swearing, I managed to figure out a method to get the file to the recipient server, but its not relying on the ssh2_scp_send routine. In place of the ssh_scp_send line, I replaced with the following: [code="php"] $sftp=ssh2_sftp($con); $stream=fopen("ssh2.sftp://{$sftp}{$DestFile}","w"); fwrite($stream,$GeneratedNavb_live); fclose($stream); [/code] That got the files to their destination. How I found this was from one resource on two pages: http://ca2.php.net/manual/en/function.ssh2-sftp.php http://ca2.php.net/manual/en/function.fwrite.php Since I had already established a successful link with the recipient server, all I had to do was open an SFTP session, write the file out (Binary safe), and everything worked as expected. No cut offs, although I am hammering the machines just to make sure this works.

Stephen — Wed, 01 Jul 2009 02:04:36 +0100

@Kevin: I KNOW you're not the developer behind the SSH code, but maybe you've experienced this if you use this part of PHP. What my project entails is taking some information from a database, formatting it very specifically, putting it into a string or file, then shove it over to a series of servers in one particular location. I `sometimes` do not successfully transfer the file in its entirety when using the following code: [code="php"] // $UploadToServer is an array of server names created by explode foreach($UploadToServer as $Server){ $DestFile="/tmp/somefile.txt"; echo "Transferring to $Server..."; // Force a cache flush ob_flush(); flush(); $con=ssh2_connect($Server,22); ssh2_auth_password($con,"user","password"); ssh2_scp_send($con,"cache/somefile.txt","$DestFile") or die("Could not transfer to $Server - Operation aborted."); // Force a cache flush again echo "OK.\n"; ob_flush(); flush(); } [/code] The file that is to be transferred is about 40k in size. However, what gets to the server is about 16k in size. I've found this to be an extremely random event. I'm also seeing that this code is sent successfully, however, the file sizes are a serious mismatch. The other thing I'm seeing is on a failed transmit, the recipients /var/log/secure log shows this: [code="text"] Jul 1 01:57:18 hsNavYyzComm2 sshd[29549]: Accepted password for foms from ::ffff:10.12.5.71 port 59937 ssh2 Jul 1 01:57:18 hsNavYyzComm2 sshd[29551]: Disconnecting: Corrupted MAC on input. [/code] Whats interesting is that I get a few KB of data TO the recipient machine before failure. It may be a streaming issue, I don't know. Now, the thing that I KNOW is working is that if I log into the source machine, I can SCP the file directly to any of those servers and it works every-single-time-without-a-hitch. Any ideas what I can peek at?

Kevin — Fri, 26 Jun 2009 08:29:22 +0100

@ jonathan: the iterate function actually uses clearstatcache() so you can also use that directly. As long as you use it. But I'd rather have people use my iterate() function so that I can implement additional fixes as I find more issues. @ Martijn: You could also use cron combined with solo (http://timkay.com/solo/) to prevent overlap and do what you want. If you need more control / intelligence on the other hand, you may need to fire actions and keep track of time yourself. I have once seen a full table-based cron implementation in PHP, I'm sure you'll find it if that is what you need. Or maybe a simple [CODE="PHP"] while(true) { if (!$ranToday && date('Hi') > 1700) { execute(); } } [/CODE]

Just to answer my own question below: The helpful chaps (ramirez in particular) in #mysql on irc.freenode spotted the fact that my mysql client versions were back-level on the centos box. I was running 5.0.27 compared to 5.1.32 on the fedora box. Still a top article though ;-)

Comment by FreudianSlip on: Improve MySQL Insert Performance

FreudianSlip — Tue, 23 Jun 2009 08:43:49 +0100

Brilliant article, works fantastic on my fedora 11 install out of the box, however I get a message from MYSQL on a centos 5 machine: "PHP Fatal error: Query failed. The used command is not allowed with this MySQL version." I've confirmed that --local-infile is ON (in the show variables output from MySQL). I've changed the /dev/shm to be 777 (as on my fedora system) from 755, confirmed the infile.txt file is being created in there ok. I've even changed the infile location to /tmp and done a mkfifo /tmp/infile.txt; chmod 777 /tmp/infile.txt but I get the same message. Any clues? I'm all googled out...

Thnx, for the article. have to say it works nice and easy. I think it's better solution then using cronjobs. Only wondering, i have to do a daily job, processing books. (about 2.000.000 records) Maybe i missing something, how to do a daily update, depending the content of a certain folder? I'm istill depending on cron or can you give some hints to solve the problem? regards Martijn

I figured out the problem. It dawned at me (At 4am) that the change to the php.ini as documented here affected just Apache. However, what I'm doing is calling php via a shell, so Apache doesn't come into play. What had to be done was go into the /var/php5/cli/php.ini and add the appropriate extension entry. No restart of services, or anything, and POOF, it worked. Thanks for this!

Stephen — Sat, 20 Jun 2009 22:52:53 +0100

This is exactly what I'm looking for, as Ubuntu didn't have it installed. Went through the step-by-step instructions and managed to get it to work. However, ONLY for the first demo. I changed the credentials, server, and command to execute, and with an additional line of [code="php"] echo "<pre>".$data."</pre>"; [/code] right at the end of the file. Perfect, I get the results I expected. However, if I copy/paste the line to check if the ssh2_connect function exists into my own code, first line, nothing else, it bombs saying that the function doesn't exist. The unique thing about this particular PHP file I'm fighting with is that its actually "CALLED" via exec. The actual command line is [code=text]php comparefile.php file1 file2[/code] It fails with "function ssh2_connect doesn't exist". I drop to the command prompt, run code posted above, and it fails as well. So why would it be that I can execute the PHP code directly from a web browser, it works perfectly as expected, but, when I run it at a command prompt, or shell out, I'm failing?

i don't install pear like that - i usually take the individual components i need and their dependencies and put them in a directory in the include path. i've done go-pear, before, as well, but all trying to do it via the command line results in are errors. i'm on a shared host and it seems like it would be a rather big oversight on their part if they let me install arbitrary extensions on their server.

@ shaunah: Well I mentioned PEAR cause if pear works chances are you can install pecl using pear just like: [CODE="BASH"] pear install -f ssh2 [/CODE] instead of: [CODE="BASH"] pecl install -f ssh2 [/CODE] @ purelife: Yeah that sure looks like a good option too! @ Alan Choyna: I think our issue is a bit beyond the scope of this article and if you're still choosing libssh instead of purelife's suggestion it might be best to create a bug report with the authors of the software to help you troubleshoot. @ Han: Do other commands work with libssh? You might test something like the following: $str = file_get_contents('/srv/www/htdocs/point/server.tmp') remotely execute: "echo '{$str}' > /home/point/etmain/server.cfg" Which could also get your config file across. At least you isolate any permission related issues that way.

Great post: I got inspired and changed your code a bit to improve for speed by using int rather than float. This also fixes the rounding problems: try [CODE="php"] var_dump(alphaID(alphaID(238328), true) == 238328); [/CODE] in your converter. Follow my link for my version of the converter.

Great function, I've used it a few times. I agree that with many problems where it seems my brain is about to break I realize that this is probably the solution. The only thing I needed to add was a limit parameter for a recent project but it was easy as all that was changed was the -1 to a default of $limit=-1 on the preg_split. Thanks!

Hi Kevin, This is really great work, thank you very much. We are going to be using it extensively in the backend of the next version of walltweet.org. I did notice this: "On success, this will return the path to the autostartup file: /etc/init.d/logparser, and you're good to go!" ... which isn't actually correct. It seems to return boolean, not a string. Just a minor point! Thanks again :D Adam Charnock

We start the backup server twice every day and run syncing script via rc.local to sync the backup server with main server and then again switch off the backup server. I look forward to your comments.

I am trying to connect to a system which requires some extra code. When connecting with a regular SSH client, I get the following message once. "The authenticity of host '192.168.255.9 (192.168.255.9)' can't be established. RSA key fingerprint is 64:bd:4e:94:a5:da:50:30:a8:67:71:7e:f0:19:1a:b7.

Thanks for the tip and the article but I couldn't get your script to work on Ubuntu Jaunty... My favorite font apart from Inconsolata is Vera Sans btw! :)

Got some good direction from your article. Had some problems with ghostscript fonts so I was searching for another solution. At the end of the day I found what I think is a more elegant solution (but limited to tiffs). Instead of using imagick and ghostscript just install libtiff (yum, apt etc.). After that its just " tiff2pdf -o output.pdf input.tiff" Thats it :), one line of code...

If you like Eclipse, I think you will adore NetBeans : ) http://kevin.vanzonneveld.net/techblog/article/my_new_ide_netbeans/

@ Patrick: Thanks. Looks indeed as if Bill was wrong. The manual said: [CODE="text"] day of week 0-7 (0 or 7 is Sun, or use names) [/CODE] It also says that lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9", '0-4,8-12'". There's no reason why this shouldn't work for weekdays.

I was going nuts with Eclipse, I installed Oxygen plugin and all sorts of errors where shown, after veryfing the version, I was using 1.5 though I installed sun 1.6, your solution worked perfectly! Thanks man! Cheers;

How is the day-of-week used (and/or)? If I wanted to schedule myjob to run at noon on the 1st Monday of the month, can I use: 0 12 1-7 * 1 myjob If not... Can it be done and how?

I believe you had it correct before Bill's note. Friday is weekday=5 (Saturday=6) and 01:00 is Friday early morning (Thursday night).

Thanks for sharing everyone! @ sweetl80: If I remember correctly Inconsolata was actually based on Consolas, but I'm not entirely sure : )

I usually use Courier New, but I will be switching to Linux, Ubuntu 9.04 distribution next month (I've tried several times but it had little annoyances - from what I see these have been fixed now), so I'll give this a try first, it does look nice.

my favourite is consolas... cleartype, and done really nicely. there is no possiblity of getting letters confused. will try this tho, it looks really nice.

I love Inconsolata. I find that I can use it at smaller optical point sizes so I can see more lines at a time (and proportionally more text across, as well). My only disappointment is that there is no bold variant so printing highlighted code does not work (I am finishing up a programming manuscript and I need to be able to highlight Java code on the static page). Heck, I'd be willing to pay money for the bold versions. -bcl

@ Filip Jukić & Pieter: Thanks. I've converted the .otf to .ttf with FontForge and got it to work with NetBeans. I've made it available here & updated the article.

Pieter — Tue, 26 May 2009 12:56:01 +0100

Sometimes to get a TTF font to appear Netbeans (or Eclipse, or IntelliJ, or any other Java based ide / program), it must be installed for the JRE used to run the IDE. Once you know which JRE it is (bundled or separate JDK), copy the TTF files into the /jre/lib/fonts directory and restart the IDE). Haven't tried it with .otf though.

@ estus: Sorry estus, I don't know what else to do, I find it kind of hard debugging this remotely. Could it be the PHP version that ships with redhat? I'm on the PEAR mailing list & I heard a LOT of complaints & bugs with that version..

Comment by Filip Jukić on: Install the Best Coding Font

Filip Jukić — Tue, 26 May 2009 12:23:00 +0100

It seems that NetBeans doesn't support OTF fonts. You might try converting it to TTF using FontForge, I decided it wasn't worth the hassle.

Gekkio — Tue, 26 May 2009 11:40:21 +0100

If you're using Ubuntu 9.04, there's also a packaged version available in the repos which should setup things perfectly: sudo apt-get install ttf-inconsolata (Requires universe repos to be enabled)

Using a nice-looking programming font makes more of a difference than I ever could've imagined. Programming in Bitstream Vera Sans Mono (my favorite), Inconsolata, Consolas, and even Monaco is just so much more enjoyable for me than using Courier. I really can't explain it; it just feels better to look at my code in a nice font.

BTW, recently I did change DPI settings on Ubuntu (144 DPI from default 96),and font looks much nicer right now. If you need DPI calculation, check: @see: http://www.raydreams.com/docs/dpi.html

Hi Kevin, it's all personal of course, but I like Envy R much better: http://damieng.com/blog/2008/05/26/envy-code-r-preview-7-coding-font-released It is also free. Few years ago I bought Pragmata font (which is right now way to expensive) and Envy R is a lookalike of Pragmata...I found Inconsolata to "square-ish"

Hey. I believe you made a mistake in your friday crontab. You say "and weekday: 5 (=Friday)" when 5 is really equal to Saturday. So really technically its Saturday morning at 1am :D

I know it's strange. I'm using PHP Version 5.1.6, with default php.ini. I was nothing changing. Maybe check my phpinfo: http://195.85.230.135/~gameone/phpinfo.php [CODE="php"] stream_set_blocking($stream, 0); [/CODE] no change [CODE="php"] var_dump($buf); [/CODE] no change and nothing return, really :/ this while loop is not perform.

Comment by Kevin on: Make SSH connections with PHP

Kevin — Fri, 22 May 2009 11:30:49 +0100

@ estus: Ok that's strange. What kind of device are you connecting to? Sometimes the shell method works better. What version of PHP are you using? Maybe setting blocking to 0 helps: [CODE="php"] stream_set_blocking($stream, 0); [/CODE] Try to echo debug information inside the while loop like: [CODE="php"] var_dump($buf); [/CODE] Cause it must return something, as echo "1" is never reached, hence $buf contains something that evaluates to true I suppose.

Comment by estus on: Make SSH connections with PHP

estus — Fri, 22 May 2009 10:57:04 +0100

I'm using source code from your article. [CODE="php"] error_reporting(E_ALL); // ini_set('display_errors', 1); if (!function_exists("ssh2_connect")) die("Error #0: Nie wykryto ssh2 na serwerze."); if(!($con = ssh2_connect("xxx", 27))){ echo "Error #1: Nie moge sie polaczyc z serwerem.\n"; } else { if(!ssh2_auth_password($con, "xxx", "xxx")) { echo "Error #2: Bledny login lub haslo.\n"; } else { echo "Wszystko dziala.\n"; if(!($stream=ssh2_exec($con, "whoami" ))){ echo "Error #3: Komenda nie moze zostac wykonana.\n"; } else { // zwraca wynik stream_set_blocking($stream, true); $data = ""; echo"0"; // helps while($buf=fread($stream,4096)){ $data .= $buf; echo $data; echo"1"; // helps } fclose($stream); } } } [/CODE] Commands works good, I know cause I can create directory. Error reporting doesn't shows any errors. :d It shows only number "0" but no "1". I was try with fgets or stream_gets_content but it doesn't works too.

@ estus: Yes maybe you're doing something wrong. But for me there's no way to tell if you don't show me how you're doing it. So please provide the source code and set error_reporting to E_ALL and show all output and what goes wrong.

Comment by Kevin on: Enhance PHP session management

Kevin — Fri, 22 May 2009 08:43:48 +0100

@ Artur Ejsmont: Since memcache doesn't support locking, e.g. ajax calls may indeed cause an unexpected sequence of saves. You can make it locking: http://www.slideshare.net/folke/netlog-what-we-learned-about-scalability-high-availability-430211 (slide 59) But this would require writing your own sessions hander (instead of using the .ini default memcache handler) and sacrificing some performance.

Worked, aside from one speedbump: [CODE="text"] dpkg: dependency problems prevent configuration of adobe-flashplugin: adobe-flashplugin depends on libcurl3; however: Package libcurl3 is not installed. dpkg: error processing adobe-flashplugin (--install): dependency problems - leaving unconfigured Errors were encountered while processing: adobe-flashplugin [/CODE] I did `sudo apt-get install libcurl3`, then `sudo dpkg -i ./install_flash_player_10_linux.deb`
