Get code line and file that's executing the current function in PHP?

Question

Imagine I have the following situation:

File1.php

Function.php

Answer 1

This is an old question but seeing as how my solution is not here, I'll provide it for posterity

     try{
        throw new Exception();
    }catch ( Exception $e ){
        $trace = $e->getTrace();
    }

    $length = 0;

    foreach ($trace as $t){
        if( $t['file'] != __FILE__ ){
            break;
        }
        ++$length;
    }
    return array_slice( $trace, ($length - count( $trace ) ));

You can throw/catch to get a clean stack trace, then you need to look for the first line that contains this file ( typically that is where it is called from ) you can also use the index of the trace if you know it, or the function.

The exception stack trace is pretty much the same as doing debug_backtrace(true).
