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。

<&#63;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,"||"));
&#63;>
Copy after login

输出内容为admin。

substr()具体描述：http://www.bitsCN.com/w3school/php/func_string_substr.htm
strpos()具体描述：http://www.bitsCN.com/w3school/php/func_string_strpos.htm

希望本文所述对大家的php程序设计有所帮助。
