php使用substr()和strpos()联合查找字符串中某一特定字符的方法，substrstrpos
本文实例讲述了php使用substr()和strpos()联合查找字符串中某一特定字符的方法。分享给大家供大家参考。具体分析如下：
要求：在下面的字符串中查找双竖线前面的字符，大多数清空下使用explode()函数，但项目过程中使用了太多的explode()，所以找到了下面的方法。
<?php $str="admin||46cc468df60c961d8da2326337c7aa58||0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,"; echo substr($str,0,strpos($str,"||")); ?>
输出内容为admin。
