PHP5实例教程 简简单单生成条形码
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:

$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);
?>
