Sau folositi PDO si prepared statement, si gata treaba, fara alte complicatii.

 Nu este mai simplu asa ?!

fisier: clean.php

<?php
  function clean($str) {
          $str = @trim($str);
       if(get_magic_quotes_gpc()) {
    $str = stripslashes($str);
      }
  return mysql_real_escape_string($str);
 }
?>

se include fisierul clean.php si apoi este simplu:

exemple:
$ceva = clean($_REQUEST['ceva']);
$ceva = clean($_POST['ceva']);

------------------------------------------------------------------------

// Apropo de fisiere si deny din .htaccess, as adauga si astea:

<Files ~ "^(.*)\.(inc|tpl|sql)$">
 Order deny,allow
 Deny from all
</Files>

 Sincer, asta este cea mai tare protectie sql injection vazuta vreodata 
Daca adaugi si extensia .html ai cel mai secure site posibil
