array2object() function

This is something that I don't want to lose, after cracking my head for hours, hence it's placed here.
This is a function which I couldn't find on the Net, a smart function to convert arrays to objects while retaining itself as arrays if necessary:

<?php
/**
* Just process non-numeric arrays. If the array has both numeric and string arrays,
* then remove numeric ones while retaining string arrays. Recurse into objects as well
* to check for any possible conversion.
**/
function array2object ($arg_array) {
    if (is_array($arg_array)) {
        $keys = array_keys($arg_array);
        foreach ($keys as $key) {
            if (is_numeric($key)) $has_number = true;
            if (is_string($key)) $has_string = true;       
            if (is_object($key)) $has_object = true;   
            };
        if (isset($has_number) and !isset($has_string)) {
            foreach ($arg_array as $key=>$value) {
                $tmp[] = array2object($value);
                }
            }
        elseif (isset($has_string)) {
            foreach ($arg_array as $key=>$value) {
                if (is_string($key))
                    $tmp->$key = array2object($value);
                }
            }
        } elseif (is_object($arg_array)) {
            foreach ($arg_array as $key => $value)
                if (is_array($value) or is_object($value))
                    $tmp->$key = array2object($value);
                    else
                    $tmp->$key = $value;
           }
        else {
            $tmp = $arg_array;
        };
    return $tmp;    //return the object
};
?>

Phew!
