warnings and solutions:-
function ereg() is deprecated:
solution: ereg() is replace into preg_match and add "/" at start and end.
otherwise use "~"
exp:-
if (!preg_match("/^<([a-zA-Z1-9]{1,$maxElem}) *(.*)>$/", $p_tag, $reg)) return false;
eragi_replace into preg_replace.
otherwise simply call this function in your page :-
error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
