Hi M
I don't understand. I don't think I'm storing it anywhere. I have it
looping through all the POST variables. If it's not an array then the
sanitize function returns a sanitized value. If it's an array then the
sanitize function calls itself again and again until it finds a single
variable and returns it as a sanitized value.

Very simple :)
when recursion happens, you return the sanitized value, but never store
it ;)

I send a variable that's an array. I'm using recursion to go through

array. The example below shows that $_POST['city'] works but
$_POST['user']
doesn't work. The array comes back blank.
Anyone see what's wrong with my code?
OUTPUT:
Array
(
[city] = New York
[user] =
)
CODE:
?php
function sanitize($userInput = '')
{
if ( is_array($userInput) )
{
foreach ( $userInput as $key = $value )
{
sanitize( $value );
}
}
else
{
if ( get_magic_quotes_gpc() )
{
return trim( $userInput );
}
else
{
return trim( addslashes($userInput) );
}
}
}
$_POST['city'] = 'New York';
$_POST['user']['firstName'] = 'Bob';
$_POST['user']['lastName'] = 'Smith';
$_POST['user']['country'] = 'USA';
foreach ( $_POST as $key = $value )
{
$_POST[$key] = sanitize( $value );
}
echo 'pre';
echo print_r($_POST);
echo '/pre';
