PHP正则表达式:根据部分的部分匹配字符串部分

I am trying to extract the age limitations from strings:

Example:
(Class 4) (0-110, 5yo+) 3m1f Good To Firm 18 fences
Return:
5yo+

Other examples would be 2yo, 3yo, 2-3yo, 4yo+, etc.

How do I match whole word if yo exists. I tried playing with \b but cannot get it to return the whole 5yo+ if yo is found :(

    This worked for me, and should work for all of the examples you have given:

    $str = '(Class 4) (0-110, 5yo+) 3m1f Good To Firm 18 fences';
    if (preg_match('/[0-9-]+yo\\+?/', $str, $matches)) {
        echo "Matched: $matches[0]
    ";
    }
