You can set the third parameter to any default value you like
::
- $my_shape = elements(array('color', 'shape', 'height'), $array, NULL);
+ $my_shape = elements(array('color', 'shape', 'height'), $array, 'foobar');
The above will return the following array
::
array(
- 'color' => 'red',
- 'shape' => 'round',
- 'height' => NULL
+ 'color' => 'red',
+ 'shape' => 'round',
+ 'height' => 'foobar'
);
This is useful when sending the $_POST array to one of your Models.
