php 截取 字符串

$a="s=/Toupiao/yulan/pid=117&title=2&selectform=1"有这样一个字符串,我想获取当中pid的值,因为pid值是不定长的,有时会pid=1,pid=12,pid=123......,那我要如何才可以截取pid的值了?

回复讨论(解决方案)

parse_str($a)

$a = "s=/Toupiao/yulan/pid=117&title=2&selectform=1";preg_match('/\bpid=(\d+)/', $a, $r);echo $r[1];
117

$a = "s=/Toupiao/yulan/pid=117&title=2&selectform=1";preg_match('/\bpid=(\d+)/', $a, $r);echo $r[1];
117
