PHP Bug Type: Feature/Change Request
Bug description: first call to set_error_handler returns same value on success
and error
Description:
------------
the first call to set_error_handler returns NULL on success. on failure,
e.g., if the desired callback function has not been declared, an E_WARNING
is thrown and NULL is returned. this makes checking for failure of this
function a little kludgy.
it would be better to always return FALSE on error, or, return the name of
the internal PHP error handler on success, which is what our custom error
handlers will be replacing on the first call.
by looking at previous bugs about this, it seems as though the
documentation was right and the code was wrong.
Reproduce code:
---------------
<?
function foo() { echo 'foo'; }
echo (NULL === set_error_handler('foo'));
echo (NULL === set_error_handler('bar'));
?>
Expected result:
----------------
1foo
Actual result:
--------------
1foo1
