If you're not looking to duplicate the rest of the string, but instead just want the offset, in the spirit of the str*pos() functions, use strcspn()
(PHP 5, PHP 7, PHP 8)
strpbrk — 在字符串中查找一组字符的任何一个字符
string
在此字符串中查找 string。
characters该参数区分大小写。
返回以找到的字符开始的子字符串。如果没有找到，则返回 false。
示例 #1 strpbrk() 示例
<?php
$text = 'This is a Simple text.';
// 输出 "is is a Simple text."，因为 'i' 先被匹配
echo strpbrk($text, 'mi');
// 输出 "Simple text."，因为字符区分大小写
echo strpbrk($text, 'S');
?>If you're not looking to duplicate the rest of the string, but instead just want the offset, in the spirit of the str*pos() functions, use strcspn()A little modification to Evan's code to use an array for the second parameter :
<?php
function strpbrkpos($s, $accept) {
$r = FALSE;
$t = 0;
$i = 0;
$accept_l = count($accept);
for ( ; $i < $accept_l ; $i++ )
if ( ($t = strpos($s, $accept[$i])) !== FALSE )
if ( ($r === FALSE) || ($t < $r) )
$r = $t;
return $r;
}
?>
