PHP Bug Type: Scripting Engine problem
Bug description: A custom handler set with set_error_handler() cannot be
unset/removed
Description:
------------
A custom error handler set with set_error_handler() cannot be removed.
The documentation says that the return value of set_error_handler() is the
previous error handler. In case of no previous error handler, NULL is
returned.
However set_error_handler() cannot be called with NULL to restore the PHP
default error handler. This results in the following:
$ php -r 'set_error_handler(NULL);'
Warning: set_error_handler() expects argument 1, '', to be a valid
callback in Command line code on line 1
Reproduce code:
---------------
<?php
function handler() {
echo "called\n";
}
set_error_handler('handler called');
set_error_handler();
?>
Expected result:
----------------
Somehow a way for removing the current error handler and restoring the
original behaviour should be possible.
Actual result:
--------------
handler called
