有两个 PEAR 包 和 Zend Framework v1.10 也将有条形码类。
不过我没有使用过其中任何一个，所以我无法推荐。
There are two PEAR packages and Zend Framework v1.10 will also have BarCode class.
I haven't used any of them though, so I cannot recommend one.
如果您仍在寻找解决方案，我已经使用了 this （改编自 ASP.NET版本）并且它生成 EAN 代码没有问题。
If you're still looking for a solution to this, I have worked with this (adapted the ASP.NET version) and it generated EAN codes without problems.
这里有一个免费的库，里面有 php 类、jQuery 插件和原型插件。它有非常
也有很好的例子访问
Here there is a free lib that have php class, jQuery plugin and prototype plugin. It has very
nice examples too visit
