[SOLVED] sanitize() ...?

[elis]

Could somebody please explain the sanitize(); function and whether it's wise to use it in adjacent to

$valude = mysql_real_escape_string(strip_tags(trim($_POST['value'])));

in regards to security?

I've tried searching for the function on PHP.net and through Google but came up short.

That function doesn't exist.  ???

That's weird. I found it by mistake here:

http://us3.php.net/manual/en/function.mysql-real-escape-string.php

In the user comments several people mentioned the function but like you said, it seems like doesn't exist.

 

Here's a sample code somebody posted

 

<?php
function sanitize($input){
    if(is_array($input)){
        foreach($input as $k=>$i){
            $output[$k]=sanitize($i);
        }

I'm still learning PHP so the chances that I misunderstood this is extremely high.

That is a user created function that someone wrote up.

Oh, okay.

Thank you, my mistake.
