Get the __FILE__ constant for a function's caller in PHP

Question

I know the __FILE__ magic constant in PHP will turn into the full path and filename of the currently executing file. But is there a way I can get the same informati

Answer 1

you should take a look at the stack trace for doing such things. PHP have a function called debug_backtrace

include "bar.php";
call_it();

//bar.php
function call_it() {
   $bt =  debug_backtrace();

   echo "Calling file: ". $bt[0]['file'] . ' line  '. $bt[0]['line'];
}

hope it helps

on the same principle you could find debug_print_backtrace useful, it do the same things but php handle the formating and printing of all the information by itself.
