If you do user_error('whatever') it'll show, as the line number for that
error, the line number on which that user_error() call is made. It'd be
nice if you could control the line number and file name that was displayed.
eg.
<?php
function test() {
user_error('whatever');
}
test();
?>
That'll say "Notice: whatever in ... on line 4" (ie. the line that the
user_error is on) instead of "Notice: whatever in ... on line 7" (ie. the
line that the call to the test() function is made).
If the displayed line numbers could be controlled by user_error then
debug_backtrace could be used to get the desired line number / file name to
display.
