A function that will return the calling class to the class using it

class A {

    //get the trace
    $trace = debug_backtrace();
    
    // Get the class that is asking for who awoke it
    $class = $trace[1]['class'];

    // +1 to i cos we have to account for calling this function
    for ( $i=1; $i<count( $trace ); $i++ ) {
        if ( isset( $trace[$i] ) ) // is it set?
             if ( $class != $trace[$i]['class'] ) // is it a different class

Hey, I forked and made a change to check to make sure the 'class' index exists since I ran into that problem in my testing. I'd suggest modifying your gist to account for the change. Unfortunately, I can't do a pull request on a gist, but, you can check out my fork to see the diff:

Thanks for sharing!

This is exactly what I needed at this moment. Thanks!
