PHP Barcode Generator

Here is an easy to use PHP barcode generator class.
Requirements: PHP Web server and GD Library (Graphics Library).

The PHP class will create a GIF barcode image or save a GIF barcode image file, here is an example:// include Barcode39 class 
include "BarCode.php"; 
// set Barcode39 object 
$bc = new Barcode39("AB3740-45"); 
// display new barcode 
$bc->draw();This example will output this barcode:

You can also easily adjust the barcode bar sizes and text size:// set object 
$bc = new BarCode("AB33740-45"); 
// set text size 
$bc->barcode_text_size = 5; 
// set barcode bar thickness (thick bars) 
$bc->barcode_bar_thick = 4; 
// set barcode bar thickness (thin bars) 
$bc->barcode_bar_thin = 2; 
// save barcode GIF file 
$bc->draw("barcode.gif");This example will save this barcode as "barcode.gif":
