runkit_function_rename
In reply to the comment made by info at lucasvd dot nl:
Runkit WILL reload classes, but the runkit_import must be called from inside an other class or object to do so.
<?php
class reload{
function __construct($file){
runkit_import($file);
}
}
new reload("myclassfile.php");
?>
runkit_import
(PECL runkit:0.7-0.9)
runkit_import — Process a PHP file importing function and class definitions, overwriting where appropriate
Description
bool runkit_import
( string $filename
[, int $flags
] )
Similar to include() however any code residing outside of a function or class is simply ignored. Additionally, depending on the value of flags , any functions or classes which already exist in the currently running environment will be automatically overwritten by their new definitions.
Parameters
- filename
-
Filename to import function and class definitions from
- flags
-
Bitwise OR of the RUNKIT_IMPORT_* family of constants.
Return Values
Returns TRUE on success or FALSE on failure.

Note that reloading classes does not work, when you're using this extension on the PHP Command Line Interface.

When using this function to override an existing class, you need to be careful in cases where the new definition 'extends' another class - it won't work.
For example,
<?php
// File 1
class BaseCls { }
class TestCls extends BaseCls {
function hi () { echo "Hi"; }
}
runkit_import('test2.php');
?>
<?php
// File 2
class TestCls extends BaseCls {
function hi () { echo "Hi again!"; }
}
?>
will NOT work. In file two, you need to omit the 'extends BaseCls'. Note however, that anything from BaseCls will still be in TestCls since it was defined originally in file 1.
From what I can tell, runkit_import defines and overwrites elements - however it does not delete.

I was experiencing problems using this function on a script. I discovered through trial and error that you CANNOT reload a function (or method of a class) if it has been called (e.g, its present in the debug_backtrace). Also you cannot redeclare a function that is used by set_error_handler.
The reasons are logical, but it took me a good 2 days of debugging to find it, hope this saves someone a headache.

Heres a nice function to reload the whole program, note, requires PHP5.1:
<?
function reload() {
$files = get_included_files();
foreach($files as $file) {
if (runkit_lint_file($file)) {
runkit_import($file);
} else {
return false;
}
}
}
?>
