How Do I Place Restrictions On Passwords (min chars, etc.)

[bradleydh]

How do I place restrictions on passwords, such as a minimum character count, and must contain at least 2 numbers and 3 letters.

you can use preg_match() to check against regular expressions. If you don't know anything about regular expressions I would suggest reading the rute users tutorial. http://rute.sourceforge.net (requires mozilla)
and stw.

an example would be:

if(preg_match("/.{6}/"), $password){
echo('The password is 6 characters');
}

It depends how complex you want to get. If you just want to check the length of characters, don't use a preg, because it's really very inefficient. What I'd suggest is using a mixture of the different String Functions, such as strlen, trim and strncmp. Other than that the suggestion of preg was a good idea. For example,

if(!preg_match("#^[a-z0-9]{6,}$#i", $sPassword)) {

echo "Invalid length, or invalid characters in password!";
} else {

echo "Valid! Nice one bruv!";
}

strlen($passwd) for string length
preg_match('/[a-z]/i', $passwd) to count number of letters
preg_match('/[^{a-z\d/i',$passwd)} to count number of non-letter-non-digits...
