Question

Is there some type of select function of sorts to create a new array selecting only certain elements with sub elements matching cases? For example, I would only like to have an array containing where [type] is “A”, so have a final array only containing [1] and [2].

[1]  
    [type] => A
    [month] => January

[2]
    [type] => A
    [month] => February

[3]
    [type] => B
    [month] => March

Thanks!

Answer 1

function is_type_a($element) { return $element['type'] === 'A'; }
$fiteredArray = array_filter($inputArray, 'is_type_a');

You can do that more concisely with an anonymous function if you have PHP 5.4.
