Description:
------------
`php -H` or `php --hide-args` should hide passed arguments from the running script but it does nothing. I've tried it on Windows and Linux.

I think that this feature can be safely removed because it doesn't work for ages (at least since PHP 5.2.10 but probably longer) and I see only a little value in it. It is also the only undocumented option at http://php.net/features.commandline.options


Test script:
---------------
php -H argv.php a b

argv.php:
<?php
print_r($argv);
?>


Expected result:
----------------
Array
(
)


Actual result:
--------------
Array
(
    [0] => argv.php
    [1] => a
    [2] => b
)

This switch works, but does not hide arguments from running script (that would be rather pointless to pass arguments and switch to make them inaccessible) but from other users using same server (using 'ps aux' for example).  

Try for yourself:

test.php:
<?php
var_dump($argv);
sleep(120);
?>

php test.php --mypass=adminadmin

on second terminal:

ps aux | grep adminadmin

expected output: 

root      9627  0.0  0.0   3256   740 pts/2    S+   21:09   0:00  php test.php --mypass=adminadmin

now try running with -H:

php -H test.php --mypass=adminadmin

and on second trerminal you should have no match, while greping only for php, you may find it, without any arguments:

ps aux | grep php

root     10012  0.8  0.8  44524  9156 pts/1    S+   21:10   0:00 php
