If you don't want to bother checking every single var with isset or empty, use this function on
every var you use:
<?php
function chk( & $var )
{
if ( !isset($var) )
{
return NULL;
}
else
{
return $var;
}
}
?>
It takes ANYTHING as argument, and returns the exact same thing, but without Notice if the var
doesn't actually exist
