bensor987 that's a separate issue. autoloader is a specific solution, while 
ability to handle such error is more generic

I think it is better to add a function autoloader, instead of just catching this error.

What about function_exists() ?

set_error_handler(function($errno , $errstr){
    if (!function_exists('there_is_no_me')) {
        function there_is_no_me(){
            echo "Here am I!\n";
        }
    }
});

Description:
------------
At the moment, call to undefined function results as "Fatal error". On the other hand, it
can be easily handled programmatically either by including required file or just defining function
dynamically.

Test script:
---------------
<?php

set_error_handler(function($errno , $errstr){
    if (strpos($errstr, 'Call to undefined function there_is_no_me()') === 0) {
        function there_is_no_me()
        {
            echo "Here am I!\n";
        }
    }
});

there_is_no_me();


Expected result:
----------------
Here am I!

Actual result:
--------------
Fatal error: Call to undefined function there_is_no_me()


------------------------------------------------------------------------
