What are common pitfalls when validating password length in PHP?

Common pitfalls when validating password length in PHP include not properly checking the length of the password or using the incorrect comparison operators. To solve this issue, you should ensure that the password length meets the required criteria using the strlen() function and compare it against the desired minimum and maximum lengths using the appropriate comparison operators. 

$password = "samplePassword123";

$minLength = 8;
$maxLength = 20;

if(strlen($password) < $minLength || strlen($password) > $maxLength) {
    echo "Password must be between $minLength and $maxLength characters long.";
} else {
    echo "Password length is valid.";
}
