php preg_match在限制内找到字符串里面的字符串

Question

This is my text:

pagination},queryId:"472f257a40c653c64c666ce877d59d2b", val:"598f257a40c653c64c666ce877d59d2b"

I need to find 472f257a40c653c64c666ce877d59d2b and 598f257a40c653c64c666ce877d59d2b.

These are all between ". I need ONLY strings between " ", and which don't exceds 32.

Here is my code:

preg_match_all('/"^(.*?){32}$"/mis', $get, $results);

Answer 1

Regex: "([a-z0-9]{32})" or (?<=")[a-z0-9]{32}(?=")

$text = "pagination},queryId:\"472f257a40c653c64c666ce877d59d2b\", val:\"598f257a40c653c64c666ce877d59d2b\"";

preg_match_all("/\"([a-z0-9]{32})\"/", $text, $match);
print_r($match);

Output:

Array
(
    [0] => Array
        (
            [0] => "472f257a40c653c64c666ce877d59d2b"
            [1] => "598f257a40c653c64c666ce877d59d2b"
        )

    [1] => Array
        (
            [0] => 472f257a40c653c64c666ce877d59d2b
            [1] => 598f257a40c653c64c666ce877d59d2b
        )
)
