Summary: "Call to undefined function" should be catchable
Status: Open
Type: Feature/Change Request
Package: Scripting Engine problem
Operating System: any
PHP Version: 5.5.0alpha1

New Comment:
In particular, this would allow developers to handle undefined functions in
batch scripts and the like. Since one can catch undefined classes (through an
autoloader), undefined class methods (through __call() and __callStatic()) and
undefined variables (through set_error_handler()), why shouldn't we be able to
catch undefined functions?

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()
------------------------------------------------------------------------
