该软件支持php4和php5两个版本，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

条码效果

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：

<SPAN style="COLOR: #0000ff"><pre class="brush:php;toolbar:false;"><OL class=dp-xml><LI class=alt><SPAN><STRONG><FONT color=#006699><SPAN class=tag><</SPAN><SPAN class=tag-name>img</SPAN></FONT></STRONG><SPAN><FONT color=#000000> </FONT></SPAN><SPAN class=attribute><FONT color=#ff0000>src</FONT></SPAN><SPAN><FONT color=#000000>=</FONT></SPAN><SPAN class=attribute-value>"test.php?codebar=BCGcode39&text=20090729"</SPAN><SPAN class=tag><STRONG><FONT color=#006699>></FONT></STRONG></SPAN><SPAN><FONT color=#000000> </FONT></SPAN></SPAN></LI></OL>
