PHP preg_match的匹配多国语言的技巧
正则:[\S]{2,32}
过滤是管用的
PHP中:
代码如下:
<?php var_dump( preg_match("/[\S\b]{2,32}/",'ج') ); echo '<hr />'; var_dump( preg_match("/[\S\b]{2,32}/",'中国') );
是不行的
需要加一个参数u,按照uniode来读码
代码如下:
<?php var_dump( preg_match("/[\S\b]{2,32}/u",'ج') ); echo '<hr />'; var_dump( preg_match("/[\S\b]{2,32}/u",'中国') ); echo '<hr />'; var_dump( preg_match("/[\S\b]{2,32}/u",'Дракон') ); echo '<hr />'; var_dump( preg_match("/[\S\b]{2,32}/u",'cc') );
