php 正则字串
下面是字串
$a = '../post/luoji/soft/aaa.chm’
$b = '../post/luoji/bbb.txt'
$c = ' post/luoji/c.rar'
$d = ’../../luo/p/d.zip‘
$e = ‘../../lio/p/p/p/p/p/p/p/p/a.tar.gz’
$f = ‘../pp/tt/p/p/p/lp/p/tttt/p/t.rpm’
要求获取成这样：
$a = 'aaa.chm‘
$b = 'bbb.txt'
$c = ' c.rar'
$d = ’d.zip‘
$e = ‘a.tar.gz’
$f = ‘t.rpm’
就是不管字串有多长只要获取最后的名称
我只会这样写
$str = "../post/luoji/aaa.chm";
$str = preg_split("/[\s,\/!]+/", $str);
echo '
';print_r($str[3]);<br><br> 不能动态获取<br><br> 怎么用正则获取？谢谢！<img src="/img/2014/05/02/11500367.gif" alt=""><br><br><font color="#FF8000">------解决方案--------------------</font><br><pre class="brush: php"><br />$a = '../post/luoji/soft/aaa.chm';<br />$a=pathinfo($a,PATHINFO_BASENAME);<br />echo $a;<br />
