Hi, bug tracking can be very difficult when you dont know where the problem is.

i propose that you create a special constant or variable like: $_BUG_ROWNUMBER and this variable (or const) will be given (at execution time) a value that represents the position OF the variable IN the php document.

for example, here the output from the die contstruct would be "error on line 3"
<?
echo "blabla";
mysql_query("wrong query") or die
    ("error on line ".$_BUG_ROWNUMBER);
?>

as you can see this would be very useful when debugging as you otherwise have to change every error message so that they will become a unique message and that you can be sure on which line it is..

thanks for your time,
