php 中生成8位条形码

[nwliu]

各位大侠：
本人有一急需，根据给定的8位数字如“71020034”生成条形码，不需要校验码位，条码就显示给定的8位数字，扫描使用。EAN-13的不要给，谢了。

UPCA条码函数。仅供参考

<?php

function UPCAbarcode($code)

谢谢大侠，不过这是11位的，我有，需要8位的。！！！请看一下我的要求。

[dzxccsu]

大哥你改一下就可以拉
1.if ( strlen($code) != 11 ) { die("UPC-A Must be 11 digits."); } =》if ( strlen($code) != 8 ) { die("UPC-A Must be 8 digits."); }
2.for ($x=0;$x<12;$x++)=》for ($x=0;$x<9;$x++)
3.for($x=6;$x<12;$x++)=》for($x=6;$x<9;$x++)

以下是我的代码，改动了你说的从12到9，程序出错。麻烦您帮忙调一下好吗，谢了！

学习，条码还是验证码？
条码是不是唯一啊！

[fxs_2008]

原来要的是打印出来的图片，收藏了

[Zijian_Zhang]

居然是打印出来的，我还没讲过用PHP打印数据的呢？？

[iasky]

google，很多
