İşte barocdes oluşturmak için basit bir PHP script:

<?php
//For displaying barcodes

//Arguments are:
//  code    Number you want outputted as a barcode

//You can use this script in two ways:
//  From a webpage/PHP script   <img src='/images/barcode.php?code=12345'/>
//  Directly in your web browser    http://www.example.com/images/barcode.php?code=12345

//Outputs the code as a barcode, surrounded by an asterisk (as per standard)
//Will only output numbers, text will appear as gaps
//Image width is dynamic, depending on how much data there is

//Get the barcode font (called 'free3of9') from here http://www.barcodesinc.com/free-barcode-font/

header("Content-type: image/png");
$file = "images/barcode.png"; // path to base png image
$im = imagecreatefrompng($file); // open the blank image
$string = $_GET['code']; // get the code from URL
imagealphablending($im, true); // set alpha blending on
imagesavealpha($im, true); // save alphablending setting (important)

$black = imagecolorallocate($im, 0, 0, 0); // colour of barcode

$font_height=40; // barcode font size. anything smaller and it will appear jumbled and will not be able to be read by scanners

$newwidth=((strlen($string)*20)+41); // allocate width of barcode. each character is 20px across, plus add in the asterisk's
$thumb = imagecreatetruecolor($newwidth, 40); // generate a new image with correct dimensions

imagecopyresized($thumb, $im, 0, 0, 0, 0, $newwidth, 40, 10, 10); // copy image to thumb
imagettftext($thumb, $font_height, 0, 1, 40, $black, 'c:\windows\fonts\free3of9.ttf', '*'.$string.'*'); // add text to image

//show the image
imagepng($thumb);
imagedestroy($thumb);
?>

Bu size yardımcı olur umarım.

Vardır two PEAR packages ve Zend Framework v1.10 da BarCode sınıfı olacaktır.

Ama bunların hiçbirini kullanmadıysanız, bu yüzden bir tavsiye edemez.

Hala bu bir çözüm arıyorsanız, ben this (ASP.NET sürüm uyarlanmış) ile çalıştım ve sorunsuz EAN kodları oluşturulur.
