PHP uses substr () and Strpos () to find a method for a particular character in a string _php tips

The example in this article describes the way PHP uses substr () and Strpos () to find a particular character in a string. Share to everyone for your reference. The specific analysis is as follows:

Requirement: Look for the character in the following string to find the characters in the front of the double vertical bar, most of which use the explode () function, but there are too many explode () used in the project process, so the following method is found.

<?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, "| |"));
? >

The output is admin.
