issues with $_POST

[Anon]

Our webhost just upgraded to php 4.2.1 and has disabled register_globals, so I've been converting our scripts over and I've come across the following problem:

I had a function "clean_input()" below that I used to strip off backslashes of user-inputted data for printing.

function clean_input(){
foreach ($_POST as $key=>$value){
$value = stripslashes($value);
$$key = $value;
}
}

---

If I echo $$key within the function, it appears to be working, but if I echo the key name outside of the function, it does nothing.

This function worked fine under php 4.0.6 with register_globals=on when I was using $HTTP_POST_VARS instead of $_POST.

Any ideas on how I can get it to work again with register_globals off?

Thanks,

Patrick

I suggest the following:

<?
$POST = array_map ('stripslashes', $POST);
extract ($_POST);
?>

This will do the same thing with a little less code. Typically, if you just want to run one function against and entire array, the array_map() function I think is faster than a foreach loop. If you want to run several functions, then do the foreach loop. The extract() will do the same thing as your $$key = $value thing.
