What are the potential pitfalls of relying solely on functions like strcasecmp() for password validation in PHP?

Relying solely on functions like strcasecmp() for password validation in PHP can be a security risk as it only performs a case-insensitive string comparison and does not provide strong password validation checks. To enhance password security, it is recommended to use a combination of functions like password_hash() for hashing passwords and password_verify() for validating passwords securely. 

$password = "mySecurePassword123";

// Hash the password
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

// Validate the password
if (password_verify($password, $hashedPassword)) {
    echo "Password is valid!";
} else {
    echo "Invalid password.";
}
