Bug description: Inconsistent behaviour of array_walk_recursive () in PHP 5
and PHP 6.
Description:
------------
In array_walk_recursive(), if we pass non-existent callback function then
it gives following output
1)for PHP 5
Warning: array_walk_recursive(): Unable to call echo() - function does not
exist in %s on line %d
bool(true)
2)for PHP 6
Warning: array_walk_recursive() : Expects parameter 2 to be valid
callback, string given in %s on line %d
NULL
In PHP5, array_walk_recursive() gives warning message the number passed
array element times, where as in PHP 6, it gives warning message only once
with return value "NULL". This is an inconsistent behavior of
array_walk_recursive() with PHP5 and PHP6.
The return value of " bool(true)" in PHP5 (1), will misguide/confuse the
developers as the documentation says array_walk_recursive() returns TRUE on
Success and FALSE on Failure.
Reproduce code:
---------------
<?php
$input = array(array(1,2), array(3), array(4,5));
var_dump( array_walk_recursive($input, 'echo'));
?>
Expected result:
----------------
/***** for PHP5 ****/
Warning: array_walk_recursive(): Unable to call echo() - function does not
exist in %s on line %d
bool(false)
/**** for PHP6 ****/
Warning: array_walk_recursive() : Expects parameter 2 to be valid
callback, string given in %s on line %d
NULL
Actual result:
--------------
/**** for PHP5 ****/
Warning: array_walk_recursive(): Unable to call echo() - function does not
exist in %s on line %d
Warning: array_walk_recursive(): Unable to call echo() - function does not
exist in %s on line %d
Warning: array_walk_recursive(): Unable to call echo() - function does not
exist in %s on line %d
bool(true)
/**** for PHP6 ****/
Warning: array_walk_recursive() : Expects parameter 2 to be valid
callback, string given in %s on line %d
NULL
