PHP regex for password validation
- by Fabio Anselmo
I not getting the desired effect from a script. I want the password to contain A-Z, a-z, 0-9, and special chars.
A-Z
a-z
0-9 2
special chars 2
string length = 8
So I want to force the user to use at least 2 digits and at least 2 special chars. Ok my script works but forces me to use the digits or chars back to back. I don't want that. e.g. password testABC55$$ is valid - but i don't want that.
Instead I want test$ABC5#8 to be valid. So basically the digits/special char can be the same or diff - but must be split up in the string.
PHP CODE:
$uppercase = preg_match('#[A-Z]#', $password);
$lowercase = preg_match('#[a-z]#', $password);
$number = preg_match('#[0-9]#', $password);
$special = preg_match('#[\W]{2,}#', $password);
$length = strlen($password) >= 8;
if(!$uppercase || !$lowercase || !$number || !$special || !$length) {
$errorpw = 'Bad Password';
