The first i would suggest is to read up on the articles about creating secure scripts (see the articles section).

1 example of vulnerable code:

PHP Code:
$WebsiteUsername $_POST['Website_Username'];
.......
if (isset(
$WebsiteUsername) && $WebsiteUsername != NULL && $UserVerify == "Verify_That")
{
    
$CustomerInfoSQL "SELECT username FROM user WHERE username='$WebsiteUsername'"
$WebsiteUsername is uncleaned user input. Should at least escaped before used in a query.

Googling "SQL Injections PHP Prevent" will probably yield some tutorials on how to secure the script.
