PHP数组从未知数量的参数合并

Question

I have an PHP array looking like this:

$array['my_data']['value'] = 'some value';
$array['my_own_data']['value'] = 'another value';
$array['different_data']['value'] = 'another value';

I need to use array_merge in PHP or such. The problem is that the number of first level keys are unknown. It could be 150 items, I don't know.

This would not work for me because of the unknown number of keys:

array_merge($array['my_data'], $array['my_own_data'], $array['different_data']);

Do I need a loop or are there something fancy?

Answer 1

This may do, if that's what you want:

$array = array_map('current', $array);

or possibly

$array = array_map(function ($a) { return $a['value']; }, $array);

This should give you

array('some value', 'another value', 'another value')
