PHP Syntax

2010-05-08T04:50:00.000-07:00

PHP scripting tag always starts with <?php and ends with ?>. PHP scripting tag can be use anywhere in the document.

There are four sets of tags which can be used to denote blocks of PHP code. Of these, only two (<?php. . .?> and <script language=”php”>. . .</script>) are always available; the others can be turned on or off from the php.ini configuration file. While the short-form tags and ASP-style tags may be convenient, they are not as portable as the longer versions. Also, if you intend to embed PHP code in XML or XHTML, you will need to use the <?php. . .?> form to conform to the XML.

To activate recognition for short tags, you must make sure that the short_open_tag switch is set to On in php.ini:[Read More...]

How PHP Is Parsed

So you have a file, and in that file you have some HTML and some PHP code. This is how it all works, assuming a PHP document with an extension of .php.

The Web browser requests a document with a .php extension.
The Web server says, “Hey! Someone wants a PHP file. Something else needs to deal with it,” and sends the request on to the PHP parser.
The PHP parser finds the requested file and scans it for PHP code.
When the PHP parser finds PHP code, it executes that code and places the resulting output (if any) into the place in the file formerly occupied by the code.
This new output file is sent back to the Web server.
The Web server sends it along to the Web browser.
The Web browser displays the output. [Read More...]

Works with the Web Server

2010-04-30T04:36:00.000-07:00

The normal process a Web server goes through to deliver a page to a browser is as follows. It all begins when a browser makes a request for a Web page. Based on the URL, the browser resolves the address of the Web server, identifies the page it would like, and gives any other information the Web server may need. Some of this information is about the browser itself, like its name (Mozilla), its version (4.08), or the operating system (Linux). Other information given the Web server could include text the user typed into form fields. [ read more...]

A Brief History of PHP

2010-04-26T04:15:00.000-07:00

In 1994, an incredibly forward-thinking man named Rasmus Lerdorf developed a set of tools that used a parsing engine to interpret a few macros here and there. They were not extravagant: a guest book, a counter, and some other “home page” elements that were cool when the Web was in its infancy. He eventually combined these tools with a form interpretation (FI) package he had written, added some database support, and released what was known as PHP/FI. [ Read More ]

You may be wondering why you should choose PHP over other languages such as Perl or even why you should learn a scripting language at all. I will deal with learning scripting languages first.
