PHP line number var? – for error reporting

[MacWorks]

I'm wondering if there's a PHP var or function that returns the current line number of the PHP script that's being executed.

I've got quite a bit of error trapping/reporting built in to a site that I'm currently developing and it would be nice to include the line number that the error processing function is being called from.

I'm imagining something like this:

ProcessError ( $PHP_LINE_NUM . " An error occurred, etc." );

OR

ProcessError ( PHP_LINE_NUM() . " An error occurred, etc." );

Your expert help is much appreciated!

After doing some more searching, I found what I was looking for at PHP.net.

The special var to report the line number is LINE (that's two underscores on both ends of the word LINE and there is not a leading dollar sign).

There are other special vars for this type of dynamic reporting like FUNCTION, FILE, etc. You can find the documentation here:
