  本文中使用的是PHP5的版本。在使用前注意要将PHP的GD模块开启。在Windows中为php_gd2.dll,Linux中为gd.so。将压缩文件解压到Apache,执行http://localhost/barcode/index.php。PHP5生成条形码见下图:

  1. Type:选择条形码类型

  2. Output:输出的图片格式

  3. Thickness:条形码高度

  4. Resolution:条形码大小

  5. Font:条形码下方的文字大小,也可不显示文字

  

 

  6. Text:条形码打印的内容

  当然,这个PHP5生成条形码程序只是将文字生成为条形码,但使用时不能灵活将其嵌入其他PHP程序,我将压缩包里面的test.php做了一些调整,使其能灵活的用于其他程序。运行时只需将条码类型和文字传给test.php即可,例如:

  http://localhost/barcode/test.php?codebar=BCGcode39&text=20090729

  或运行http://localhost/barcode/mytest.php

  mytest.php代码:

  PHP5生成条形码test.php代码:

  

  // Including all required classes require(class/BCGFont.php);

  require(class/BCGColor.php); require(class/BCGDrawing.php);

  /*BCGcodabar,BCGcode11,BCGcode39,BCGcode39extended,BCGcode93, BCGcode128,BCGean8,BCGean13,BCGisbn,BCGi25,BCGs25,BCGmsi,

  BCGupca,BCGupce,BCGupcext2,BCGupcext5,BCGpostnet,BCGothercode*/ $codebar = $_REQUEST[codebar]; //该软件支持的所有编码,只需调整$codebar参数即可。

  // Including the barcode technology include(class/.$codebar..barcode.php);

  // Loading Font $font = new BCGFont(./class/font/Arial.ttf, 10);

  // The arguments are R, G, B for color. $color_black = new BCGColor(0, 0, 0);

  $color_white = new BCGColor(255, 255, 255); $code = new $codebar();

  $code->setScale(2); // Resolution $code->setThickness(30); // Thickness

  $code->setForegroundColor($color_black); // Color of bars $code->setBackgroundColor($color_white); // Color of spaces

  $code->setFont($font); // Font (or 0) $text = $_REQUEST[text]; //PHP5生成条形码将要数据的内容

  $code->parse($text); /* Here is the list of the arguments

  1 - Filename (empty : display on screen) 2 - Background color */

  $drawing = new BCGDrawing(, $color_white); $drawing->setBarcode($code);

  $drawing->draw(); // Header that says it is an image (remove it if you save the barcode to a file)

  header(Content-Type: image/png); // Draw (or save) the image into PNG format.

  $drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
