Straightforward function - simply connect to the database and execute a query, similar to this function bellow.

<?php

function check_password($username, $password) {
// Create connection
$db = new mysqli('localhost','database_user','database_pass','database_name');

// Check for errors
if($db->connect_errno){
echo
$db->connect_error;
}

// Execute query
$result = $db->real_query("Select * From users Where username='$username' And password='$password'");

// Always check for errors
if($db->connect_errno){
echo
$db->connect_error;
}

return
$result == true;
}
?>

Very easy.

Replace database_user, database_pass and database_name with the proper names, and the text inside real_query with your actual query.

Don't forget the quotes on either side (except for numbers, there you can omit them) otherwise it won't work. Hope that helps someone.
