strpos
(PHP 3, PHP 4, PHP 5)strpos -- Find position of first occurrence of a string
例子 1. strpos() examples<?php
$mystring = 'abc';
$findme = 'a';
$pos = strpos($mystring, $findme);// Note our use of ===. Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
echo "The string '$findme' was not found in the string '$mystring'";
} else {
echo "The string '$findme' was found in the string '$mystring'";
echo " and exists at position $pos";
}// We can search for the character, ignoring anything before the offset
$newstring = 'abcdef abcdef';
$pos = strpos($newstring, 'a', 1); // $pos = 7, not 0
