[RESOLVED] Debugging: Show script line location?

[Joseph_Sliker]

Hi;

I know that I can echo the filename of a .php script by using the line:

echo $_SERVER['PHP_SELF'];

Is there a similar command that will also show the specific LINE number being processed (ie. like one sees when there is an error message)?

For example if I am composing/debugging a very long page that runs all kinds of different functions or commands, could I put something like:

//START some specific section that might get moved around if I add a bunch of code above it
echo $SERVER['PHP_SELF'] ; echo "$SERVER[..some variable that shows the script line number processed at this point..]";
//END some specific section that might get moved around if I add a bunch of code above it

I've looked at the $_SERVER[] variables on php.net but don't seen anything that corresponds exactly to what I'm looking for

Thanks.

See "magic constants" for the current line number, file, and other useful things. Also see [man]debug_backtrace/man and [man]debug_print_backtrace/man for ways to get other useful debug info.

ive done things like this:

if($size == '' or !is_numeric($size))die(error_handler(__FUNCTION__,__LINE__,'$size must be passed'));

The line

echo __LINE__;

Does exactly what I want. Thanks!

It even holds up with includes, so

echo "<br>".__FILE__." line:". __LINE__."<br>";

Let's me know where to start digging!

Thanks!
