php - How to write regular expression for this kind of a string?

Question

I will get this kind of string from the $_POST array:

$string = "\"Search Text\"";

OR

$string = '\'Search Text\'';

How I will check whether the Search Text included in double quotes or single quotes using regular expression.

Base on Kolink Answer I did like this

echo $subject = "'Search Text'";
$pattern = "/['\"](?=;$)/";
preg_match($pattern, $subject, $matches, PREG_OFFSET_CAPTURE, 3);
print_r($matches);

Its not giving any result. :(

Answer 1

因此，为了澄清，您的用户将$string = "Search Text";在文本框中发送类似的内容？或者这只是您的服务器端代码的一部分？

如果是第一个，您只需搜索/['"](?=;$)/，它就会告诉您使用的是单引号还是双引号。

如果是第二个，那么您的问题毫无意义，因为引号不是字符串的一部分。
