PHP need to trim all the $_POST variables

Question

Need you help in an unusal situation. I need to trim all the $_POST variables.

Is there any way I can do it at a single shot i.e., using a single function?

You can also use this code I wrote in case you want to sanitize a string OR an array with one function:

function sanitize ($value) {
    // sanitize array or string values
    if (is_array($value)) {
        array_walk_recursive($value, 'sanitize_value');
    }
    else {
        sanitize_value($value);
    }

    return $value;
}

function sanitize_value (&$value) {
    $value = trim(htmlspecialchars($value));
}

Simply use it like this:

$post_sanitized = sanitize($_POST);
$apple_sanitized = sanitize('apple');
