replace eregi(/find/,str) with preg_match(//,str)
add function exists for function that not exists in php5.4.3. for example: <code> if(!function_exists("session_is_registered")){ function session_is_registered($var){ return isset($_SESSION[$var]); } } if(!function_exists("session_register")){ function session_register($var){ $_SESSION[$var]=$_GLOBALS[$var]; } } </code>
