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';
?>

#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]
