研究好半天也没弄对

将 
/aaa/bbb/ccc

拆分成 
/aaa
/bbb
/ccc

我写的不对啊
preg_match('/(\/\w+)+/i', '/aaa/bbb/ccc', $matches);


回复讨论(解决方案)

一定要用正则吗,我觉得用explode函数也不错呀。

$str = '/aaa/bbb/ccc';$matches = explode('/',$str); //explodeecho '/'.$matches[1];  // /aaaecho '/'.$matches[2];  // /bbbecho '/'.$matches[3];  // /cccpreg_match_all('@\/[a-z]{3}@i', $str, $matches); //正则echo $matches[0][0];  // /aaaecho $matches[0][1];  // /bbbecho $matches[0][2];  // /ccc


要这样写
preg_match_all('/(\/\w+)/i', '/aaa/bbb/ccc', $matches);

$matches[1] 即是

3楼正解,是要匹配所有符合要求的,因此要用函数preg_match_all。

个人觉得没有必要去用正则,explode()完全可以做到你想要的结果,何必要舍近求远呢,当然也得看实际情况....
