If you set_error_handler, then you get automatically line number and
filename.
Read through: http://www.php.net/manual/en/function.set-error-handler.php
(read user comments! there are undocumented things)
Then set up your handler like this:
$_old_error_handler = set_error_handler("myErrorHandler");
function somefunction(){
#do some stuff
trigger_error("Something went wrong, don't know why, sorry",
E_USER_ERROR);
}
function myErrorHandler($level, $message, $file, $line, $context){ #$context
contains _ALL_ variabels in scope when error happened
echo "D'oh, an error has occurred: $message.\n";
echo "It happened in file $file at line $line and it is a $level-error";
}
the most beauty about that is that you can also cover errors you didn't
handle (e.g. if fopen triggers a warning or whatever)
