Question

I have my data in ArrayObject, simply representing an array. I need to filter the data, function array_filter() would work great. However, it does not work with ArrayObject as argument. What’s the best way to treat with this? Is there any standard function which handles filtering for me?

Example:

$my_data = ArrayObject(array(1,2,3));
$result = array_object_filter($my_data, function($item) { return $item !== 2; });

Is there any array_object_filter function?

Answer 1

How about you export it to an actual array, and then create a new Array Object?

$my_data = new ArrayObject(array(1,2,3));
$result = new ArrayObject( 
    array_filter( (array) $my_data, function($item) { 
         return $item !== 2; 
    })
);
