Hello @kartik,

This is how you do it:

set_error_handler(function($errorType){
    if(error_reporting() & $errorType){
        ?><pre><?
        debug_print_backtrace();
        ?></pre><?
    }
}) ;

It requires PHP 5.3+ since it uses a closure. If you need lower PHP support just convert the closure to a normal function.
