PHP條碼圖像生成器

Question

我需要一個能夠生成條形碼圖像文件的類，最好與最常見的標準兼容。

我在尋找基於個人經驗的建議/建議。

非常感謝

Answer 1

有two PEAR packages和Zend Framework v1.10也會有條碼類。

雖然我沒有使用過它們，所以我不能推薦一個。

Answer 2

如果你仍然在尋找解決方案，我已經與this（適應ASP.NET版本）合作，它生成的EAN代碼沒有問題。

這裏是產生barocdes一個簡單的PHP腳本：

<?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); 
?> 

希望這有助於你。
