/**
 * Replaces elements from passed arrays into the first array
 *
 * array_replace() replaces the values of array1 with values having the 
 * same keys in each of the following arrays. If a key from the first array
 * exists in the second array, its value will be replaced by the value from
 * the second array. If the key exists in the second array, and not the
 * first, it will be created in the first array. If a key only exists in
 * the first array, it will be left as is. If several arrays are passed for
 * replacement, they will be processed in order, the later arrays
 * overwriting the previous values.
 *
 * @since PHP 5.3.0
 * @param array $array1     The array in which elements are replaced
 * @param array $array2...  The array from which elements will be extracted
 * @return array Returns an array, or NULL if an error occurs
