Bug description: require_last - for terminating code that must be executed
after all includes.
Description:
------------
Because files are included at run time where the instruction is located,
it may not ever be evaluated. This is to be expected.
However, this creates a problem with code that may call a function that is
in one of the preceding included files. You generally want to call that
function LAST, only after you've included all other files. (This is for
nested include relations)
The only scenario I have found this relevant thus far is calling php
functions using AJAX.
Reproduce code:
---------------
---
>From manual page: function.include-once
---
I'll provide a simple example, because the one I came upon is too large.
Imagine you have fileA.php:
<?php
include_once "fileB.php";
include_once "fileC.php";
include_once "callA.php";
//when fileB.php includes callA.php and callA calls fncA and it tries
to call fncC, although fncC is in this files includes list, that line has
yet to be executed, therefor it will not be able to find the function. If
you could include_last "callA.php", then the first include_last "callA.php"
in fileB.php would be ignored, and the callA.php in fileA.php would be
included after fileC.php is included. =)
function fncA() { fncC(); }
?>
You normally wouldn't do the following, but if there was generic code to
call an AJAX function here it would do this.
fileB.php:
<?php
//reminder that include_once "fileC.php"; hasn't been executed yet.
include_once "callA.php";
?>
fileC.php:
<?php
fncC(){ print "hello"; }
?>
callA.php:
<?php
fncA();
?>
I posted another example in the comments of include_once.
Expected result:
----------------
function not found.
Actual result:
--------------
with include_last, the function will be called and "hello" would be
printed.
