2019-07-24T23:42:00.000-07:00

Working with images and text, we need to set image size based on font size is very useful for dynamic image processing. like CAPTCHA and text images. if you looking for PHP script to set image size based on font size here is the solution for you.

<?php


if($_GET['fontsize']!="" and is_numeric($_GET['fontsize']))
$size=$_GET['fontsize'];
else
$size=20;


define("F_SIZE", $size);
define("F_ANGLE", 0);
define("F_FONT", "verdana.ttf");


$text = "W3 Lessons";

$Leading=0;
$W=0;
$H=0;
$X=0;
$Y=0;

$_bx = imagettfbbox(F_SIZE, F_ANGLE, F_FONT, $text);
$s = preg_split("/\n]+/", $text);  // Array of lines
$nL = count($s);  // Number of lines

$W = ($W==0)?abs($_bx[2]-$_bx[0]):$W;
$H = ($H==0)?abs($_bx[5]-$_bx[3])+2+($nL>1?($nL*$Leading):0):$H;

$W*=1.05;
$H*=1.5;

$img = @imagecreate($W+8, $H) or die("Cannot Initialize new GD image stream");

$white = imagecolorallocate($img, 255,255,255);
$txtColor = imagecolorallocate($img, 29,56,131);

// Adjust padding right:
$W+=8;
$bgwhite = imagecolorallocatealpha($img,238,238,238,0);
imagefilledrectangle($img, 0, 0,$W,$H, $bgwhite);

$alpha = "".range("a", "z");
$alpha = $alpha.strtoupper($alpha).range(0, 9);

// Use the string to determine the height of a line
$_b = imageTTFBbox(F_SIZE, F_ANGLE, F_FONT, $alpha);
$_H = abs($_b[5]-$_b[3]);
$__H = 0;

// Use the string to determine the width of a line
$_b = imagettfbbox(F_SIZE, F_ANGLE, F_FONT, $text);
$_W = abs($_b[2]-$_b[0]);

// Final width and height
$_X = abs($W/2)-abs($_W/2);
$__H += $_H;

imagettftext($img, F_SIZE, F_ANGLE, $_X, $__H, $txtColor, F_FONT, $text);

header("Content-Type: image/png");
imagepng($img);
imagedestroy($img);
// END EMAIL IMAGE  
exit();

Simple Two way Encryption and Decryption Function PHP

2018-01-23T21:52:00.000-08:00

Hello guys, after a long time, I came back to my blog with new flavor of articles, and I am plan to concentrate my blog half my working day here after. So my followers can expect valuable development ideas from me through comment and feed.

Here we go our come back article, Here now I teach you the Two way encryption and decryption method with full explanation.

Objective Build a function for Two Way Encryption and Decryption:

Encrypt as well as Decrypt our given string with our own Encrypt Decrypt Key and Initiative Vector (IV) (?), with Advanced Encryption Standard (AES) (?) this method is highly secure method all time ever with few PHP functions to build Two way Encryption and Decryption.

Functions Involved in Two Day Encryption and Decryption.

hash - Generate a hash value (message digest)

string hash ( string $algo , string $data [, bool $raw_output = false ] )

substr - Return part of a string

string substr ( string $string , int $start [, int $length ] )

base64_encode - Encodes data with MIME base64

string base64_encode ( string $data )

base64_decode - Decodes data encoded with MIME base64

string base64_decode ( string $data [, bool $strict = false ] )

openssl_encrypt - Encrypts data

string openssl_encrypt ( string $data , string $method , string $key [, int $options = 0 [, string $iv = "" [, string &$tag = NULL [, string $aad = "" [, int $tag_length = 16 ]]]]] )

openssl_decrypt - Decrypts data

string openssl_decrypt ( string $data , string $method , string $key [, int $options = 0 [, string $iv = "" [, string $tag = "" [, string $aad = "" ]]]] )

Two Encryption & Decryption Function

/*
Written by: Jailani M, http://www.W3Lessons.com
Defineds:
ED_KEY - Encryption and Decription key your choice
IV_KEY - INITIATIVE VECTOR your choice
*/
define("ED_KEY","your_key");

    $encrypt_method = "AES-256-CBC";
    $key = hash( 'md5', ED_KEY );
    $iv = substr( hash( 'md5', IV_KEY ), 0, 16 );
    $encoded_string = base64_encode( openssl_encrypt( $string, $encrypt_method, $key, 0, $iv ) );
    return $encoded_string;
}

function w3_decode($string)
{
    $encrypt_method = "AES-256-CBC";
    $key = hash( 'md5', ED_KEY );
    $iv = substr( hash( 'md5', IV_KEY ), 0, 16 );

curl_setopt($ch, CURLOPT_REFERER, "");
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$response = curl_exec($ch);


// Then, after your curl_exec call:
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);
curl_close($ch);

If you need to select records from MySQL table records with date today and last 30 days records.
based on the Server date.

MySQL select today and last 30 days records

SELECT * FROM posts WHERE 
date_of_create BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE();

In case if your field data type were DATETIME format you need to convert your datetime format into date

SELECT DATE_FORMAT(date_of_create, '%m/%d/%Y') FROM posts
WHERE   date_of_create BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE()

MySQL Date Functions

2012-10-24T21:49:00.000-07:00

Working with date in MySQL is very important for date based query processing. today we going to get some important MySQL date functions frequently used in projects.

Here is the date functions with example queries from Article table have the column date_of_post

CURDATE() - Return the current date

Example:

SELECT * FROM articles WHERE date_of_post = CURDATE()

DAY() - Return day number from the date column

Example:
SELECT * FROM article WHERE DAY(date_of_post) = 1

MONTH() - Return Month number from the date column

Example:
SELECT * FROM article WHERE MONTH(date_of_post) = 2

YEAR() – Return year number from the date column

Example:
SELECT * FROM article WHERE MONTH(date_of_post) = 2011

LAST_DAY() - Return Last date as number, From the month of the date column

Example:

$s = preg_split("/\n]+/", $text);  // Array of lines
$nL = count($s);  // Number of lines

$W = ($W==0)?abs($_bx[2]-$_bx[0]):$W;
$H = ($H==0)?abs($_bx[5]-$_bx[3])+2+($nL>1?($nL*$Leading):0):$H;

$img = @imagecreate($W+8, $H) or die("Cannot Initialize new GD image stream");

$white = imagecolorallocate($img, 255,255,255);
$txtColor = imagecolorallocate($img, 255,50,0);

// Adjust padding right:
$W+=8;
$bgwhite = imagecolorallocatealpha($img,238,238,238,0);
imagefilledrectangle($img, 0, 0,$W,$H, $bgwhite);

$alpha = "".range("a", "z");
$alpha = $alpha.strtoupper($alpha).range(0, 9);

// Use the string to determine the height of a line
$_b = imageTTFBbox(F_SIZE, F_ANGLE, F_FONT, $alpha);
$_H = abs($_b[5]-$_b[3]);
$__H = 0;

// Use the string to determine the width of a line
$_b = imagettfbbox(F_SIZE, F_ANGLE, F_FONT, $text);
$_W = abs($_b[2]-$_b[0]);

// Final width and height
$_X = abs($W/2)-abs($_W/2);
$__H += $_H;

imagettftext($img, F_SIZE, F_ANGLE, $_X, $__H, $txtColor, F_FONT, $text);

{
 $content = file_get_contents("http://www.google.com/ig/calculator?hl=en&q=$amount."."$from=?$to"); 
 // Remove Spaces on API Output
 $content = preg_replace('/[^A-Za-z0-9.]+/','',$content);
 // Match All Currency values 0-9 and .(decimal)
 preg_match_all('/([0-9.]+)/', $content, $m);
 
 // Convert values with 3 decimal points
 $currency[$from] = sprintf("%.3f",$m[0][0]);
 $currency[$to] = sprintf("%.3f",$m[0][1]);

Water mark in PHP

2012-09-22T00:26:00.000-07:00

Processing with image in PHP, Adding watermark is very help full. Add Image Watermark with original image is also help to protect our images here is my solution to Add Water Mark in PHP

Prepare an transparent image with exact same size of the original image. Transparent PNG with Text by overlap original image to create a final watermark added image.

<?php
// Original Image Path
$image= "images/original_image.jpg";  

header("Content-type: image/jpeg");
header("Content-Disposition: inline; filename=$image");

switch (TRUE) {
case stristr($image,'jpg') :
$photoImage = ImageCreateFromJPEG("$image");
break;
case stristr($image,'gif') :
$photoImage = ImageCreateFromGIF("$image");
break;
case stristr($image,'png') :
$photoImage = ImageCreateFromPNG("$image");
break;
}

ImageAlphaBlending($photoImage, true); 

// Same Size PNG Watermark Image with Transparency
$logoImage = ImageCreateFromPNG("watermark_image.png"); 
$logoW = ImageSX($logoImage); 
$logoH = ImageSY($logoImage); 

// were you see the two 1's this is the offset from the top-left hand corner!
ImageCopy($photoImage, $logoImage, 1, 1, 0, 0, $logoW, $logoH); 

imagejpeg($photoImage);
// if you want to save add the following line
imagejpeg($photoImage,"images/final.jpg");

ImageDestroy($photoImage); 
ImageDestroy($logoImage); 

?>

2012-09-21T23:06:00.002-07:00

Processing multiple records through Text Area, We may need to convert that text area values into array from every line of text in that TextArea. here is my solution to "Convert TextArea to Array"

<!DOCTYPE>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Text Area to Array</title>
</head>
<body>

<?php
// Check Form Submission
if(isset($_POST['submit']))
{
 // Capture cities text into variable
 $text = ucwords($_POST['cities']);
 // Replace entry new line with Comma(,)
 $cities = preg_replace("~\s*[\r\n]+~", ', ', $text);
 // Explode by Comma(,) and trim if any white spaces with array_map
 $cities = array_map('trim',explode(",",$cities));
 // final output as array
 echo "<pre>";
 print_r($cities);
 echo "</pre>";
}


?>

<form action="" method="post">
  <h2>Convert Text Area to Array</h2>
  <p>Enter each city every line<br />
    <textarea name="cities" cols="50" rows="10" id="keywords"></textarea>
    <br />
    <br />
    
    <input name="submit" type="submit" value="Submit Cities" id="submit" />
  </p>
