PHP:如何在字符串中查找 * 通配符的出现 [英] PHP: How to find occurrence of a * wildcard character in a string

问题描述

也许我问的问题有点太平庸了，但我真的不知道如何使用 PHP 检查字符串中是否出现通配符 (*).

Maybe I'm asking a bit too banal question, but I really cannot figure out how to check for an occurrence of a wildcard (*) character in a string using PHP.

示例字符串:*bcd OR ab*d OR abc*

An example string: *bcd OR ab*d OR abc*

无论我尝试使用什么 PHP 函数，它的行为都是不可预测的.我只需要知道通配符是否在字符串中.非常感谢您的回复！

Whatever PHP function I try to use, it behaves unpredictably. I just need to know whether the wildcard character is or is not in a string. Thank you very much for replies!

推荐答案

if (strpos($mystring, '*') === false) {
    echo "Wildcard was not found in the string '$mystring'";
} else {
    echo "Wildcard was found in the string '$mystring'";
}

基于 http://php.net/manual/en/function 中的示例.strpos.php
