Read and write to property of multidimensional array (property is string var)

get_set_array_element

function getArrayElement($array, $path, $pathDelimiter = '->')
{
        // searching for element
        $current_array = &$array;
        $keys        = explode($pathDelimiter, $path);
        foreach ($keys as $key)
        {
            $current_array = &$current_array[$key];
        }

        return $current_array;
}

function setArrayElement(&$array, $path, $value, $pathDelimiter = '->')
{
        // searching for element
        $current_array = &$array;
        $keys        = explode($pathDelimiter, $path);
        foreach ($keys as $key)
        {
            $current_array = &$current_array[$key];
        }

        $current_array = $value;
}

This 2 functions can get ot set array element by path.

Usage example:

array( 'b' => 'val1', 'c' => 'val2' ), 'd' => array( 'e' => 'val3', 'f' => 'val4' ) ); print_r($test_arr); echo "\n"; print_r(getArrayElement($test_arr,'a->b')); echo "\n"; setArrayElement($test_arr,'a->c', 'ololo'); setArrayElement($test_arr,'b', array('1'=>2)); print_r($test_arr);
