$_POST Global

[sissy]

Hi Folks are we all well,

Since $_POST is a global why cant i do this.

$_POST = strip_tags($_POST);

Yet i can do this.

$_POST = str_replace("'", "", $_POST);

I am a bit lost as to why the first is not working?

Any ideas, thanks.

Because $_POST is an array. You can use an array with no problems with str_replace, but apparently not so with strip_tags.

Ahhh yes good call Jedi well i guess i could use string replace with an array list of things and filter out most stuff that way it will be global then instead of coding a function and using it for ever form input which is anoying to me 🙂

// can add what ever is need here
$filter = array("'", "$", "..", "\\\");
$_POST = str_replace($filter, "", $_POST);

The above could be handy for others who knows 🙂

thanks Jedi
