I have an array in the following structure
Array ( [members] => Array ( [0] => Array ( [nr] => 2 [email] => email1 ) [1] => Array ( [nr] => 6 [email] => email2 ) [2] => Array ( [nr] => 3 [email] => email3 ) ) [title] => List members ) I want to delete items [3] => Array () by nr, like unset [nr] => 3, so how should I do this?
I would use array_filter instead of unset I'd filter the values that you actually need.
$array['members'] = array_filter($array['members'], function($member) { return $member['nr'] !== 3; }); You have to loop over members items and check if nr has the value you want. Then, you could use unset() to remove the entry :
foreach ($array['members'] as $key => $item) { if (isset($item['nr']) && $item['nr'] == 3) { unset($array['members'][$key]) ; } } You can directly use unset($main['members'][2]['nr']); if you dont want to use foreach loop
