Possible to find last executed function or last parsed line?

[duveit]

I have this module which I intend to use for pdfparsing, and it dies one me without a word. Looking at the code it's littered with die(''), meaning there is a lot of places it may die, but without a word why.

So I was wondering if there is a way to include the last function called or the line number at which current execution is made?

Thinking I could then do a stringreplace of the die('')'s to a more meaningful errormsg.

Other approaches/ideas on this is also appriciated!

Maybe http://www.w3schools.com/php/php_exception.asp can help you out

Thanks for reply, but it didnt really tell wether it's possible to find the last executed function or at which position the php-parser is currently at.

No indeed. It's a way to handle errors. With try / catch you can send the messages you want and that makes it a lot easier to find errors like the ones you have.

How about debug_backtrace (or debug_print_backtrace)?

I ended up using function trigger-error , doing replace die(''); with {trigger_error("I'm dying.. ", E_USER_ERROR); die('dead');} Which gave me the line it was triggered on.

Thanks for input!

Another possibility is to do this:

die("It died in file: " . __FILE__ . " on line " . __LINE__);

But triggering errors is a lot more helpful.

Ah thanks, that was exact what I was looking for in the first place

You should not use die...it is not a form of error handling because it kills the whole script. Not what you want in the real programming world.

True enough, but as with this situation, it's not my code, and it was the easiest way of spotting the error. I found the massive use of die('') strange myself.
