php u9

怎么用PHP验证中文字母和数字、

[\u4E00-\u9FA5]这个可以验证中文吗？？？？？急

回复讨论(解决方案)

[\x4E00-\x9FA5]

应该是 [\x4E00-\x9FCF]
现在的软件基本都支持 unicode 6.1 版本啦，不能再用老三篇

不行，[\u4E00-\u9FA5] 是 js 正则用的

既然你想到这样用，可见你用的是 utf-8 编码了
php 正则中要写作 [\x{4e00}-\x{9fa5}] 还要加上 u 修饰符
不过既然有了 u 修饰符，那么 \w 就已经包含中文了

应该是 [\x4E00-\x9FCF]
现在的软件基本都支持 unicode 6.1 版本啦，不能再用老三篇

if (ereg('^[\x4E00-\x9FCF]{1,100}$','哈哈哈哈只')){
     echo "通过";
}else{
     echo "错误";
}
?>
还是错误呢、

gb2312不明白js也用的是gb2312

浏览器会将所有传入的数据统一化为 unicode 编码，对于简体中文环境就是 ucs-2
而 \u4E00-\u9FA5 正是汉字的 ucs-2 的编码范围

是的，明白。

但是你说我在eregi()中怎么就用不了呢

if(eregi()){
ecjp '正确';
}

谢谢!!!

echo '正确';

是不是ereg被支持了呢？？？？

ereg 系列使用的是 POSIX 正则
preg 系列使用的是 PCRE 正则
两者不兼容！

而 ereg 函数组将在不久的将来废除，建议不要使用
