EXAMPLES

       Example #1

	      debug_print_backtrace(3) example

	      <?php
	      // include.php file

	      function a() {
		  b();
	      }

	      function b() {
		  c();
	      }

	      function c(){
		  debug_print_backtrace();
	      }

	      a();

	      ?>

	      <?php
	      // test.php file
	      // this is the file you should run

	      include 'include.php';
	      ?>

	      The above example will output something similar to:

	      #0  c() called at [/tmp/include.php:10]
	      #1  b() called at [/tmp/include.php:6]
	      #2  a() called at [/tmp/include.php:17]
	      #3  include(/tmp/include.php) called at [/tmp/test.php:3]
