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

498)this.width=498;' onmousewheel = 'javascript:return big(this)' alt=条码效果 src="http://www.bkjia.com/uploadfile/2013/0904/20130904094617982.jpg" width=615 height=557>

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 class="tag-name">img</span></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>
