First, you need to download a barcode font. Here is a freeware one:
http://www.squaregear.net/fonts/free3of9.shtml
Save it to a folder on your server, and place the following code in a
file in the same folder as the font and name it for example "barcode.php":
<?php
// specify a barcode font
$barcodeFont="./FREE3OF9.TTF";
// check that a code is provided
$code=$_GET['code'];
$size=$_GET['size'];
if($code==''){
exit;
}
if($size==''){
$size=20;
}
// image width and height
$width=barcodeWidth($code, $size);
$height=$size;
// Set the content-type
header("Content-type: image/png");
// Create the image
$im = imagecreatetruecolor($width, $height);
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, $width-1, $height-1, $white);
// The text to draw
$text = "*$code*";
// Add the text
imagettftext($im, $size, 0, 0, $size, $black, $barcodeFont, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
// function to retrieve barcode width
function barcodeWidth($code, $size){
global $barcodeFont;
$arrInfo=imagettfbbox($size, 0, $barcodeFont, "*$code*");
return ($arrInfo[2]-$arrInfo[0]);
}
?>
To print a barcode into any webpage, insert this HTML code in the page:
<img src="barcode.php?code=123456">
Of course, '123456' should be replaced with whatever code youo wish to
display.
