Would it not be wiser to leverage the build-in password validation rules than rolling your own with Regex

PHP regex - combination of multiple condition
I have to do validation against the password by the following conditions
- Uppercase and Lowercase
- Numbers
- Special characters
among three any two combination is enough to meet my requirements. It must be achieved by regex.
E.g 'password' => 'required|min:8|regex:/^XXXXX$/',

@tykus Yes, It will be achieved by laravel build in validation rules. But i want to achieve it by regex.

You could just use the Laravel built in validation rules.
$request->validate([ 'password' => 'required|string', ]);
if its not what you really wanted the documentation could help you.

@TwentyHxte Yes i know that, but i want to make a regular expression for that.

@peermydeen okay but what would be the purpose of using a regex ?
Level 1
@peermydeen You could probably do it this way if you really want to use a regex:
^(?=.*[a-zA-Z])(?=.*[0-9]|.*[!@#\$%\^&\*]|.*[a-zA-Z]).{2,}$
Any string containing uppercase or lowercase letter and number or special characters should match.

@TwentyHxte Thanks for your answer. But it doesn't meet my requirements so, i made below logic to solve my issue.
$patterns = ['a-z', 'A-Z', '0-9', '`~!@#$%^&*()\-=_+\[\]\{\}\\|;:\'\",.\/<>?'];
$i = 0;
foreach ($patterns as $pattern) {
// Enough to meet any two pattern
if ($i == 2) {
break;
}
if (preg_match('/[' . $pattern . ']/', $password)) {
$i++;
}
}
return ($i == 2) ? true : false;
