I noticed that : PHP ignored arguments type when using array_walk() even if there was declare(strict_types=1) . See this code as an example ... <?php declare(strict_types=1); $fruits = array("butter" => 5.3, "meat" => 7, "banana" => 3); function test_print(int $item2, $key) { echo "$key: $item2<br />\n"; } array_walk($fruits, 'test_print'); ?> The output is : butter: 5 meat: 7 banana: 3 whilst the expecting output is : Fatal error: Uncaught TypeError: Argument 1 passed to test_print() must be of the type integer because "butter" => 5.3 is float I asked someone about it and they said "this was caused by the fact that callbacks called from internal code will always use weak type". But I tried to do some tests and this behavior is not an issue when using call_user_func(). ---- Server IP: 208.43.231.9 Probable Submitter: 51.223.91.96 ---- Manual Page -- http://php.net/manual/en/function.array-walk.php Edit -- https://master.php.net/note/edit/121980 Del: integrated -- https://master.php.net/note/delete/121980/integrated Del: useless -- https://master.php.net/note/delete/121980/useless Del: bad code -- https://master.php.net/note/delete/121980/bad+code Del: spam -- https://master.php.net/note/delete/121980/spam Del: non-english -- https://master.php.net/note/delete/121980/non-english Del: in docs -- https://master.php.net/note/delete/121980/in+docs Del: other reasons-- https://master.php.net/note/delete/121980 Reject -- https://master.php.net/note/reject/121980 Search -- https://master.php.net/manage/user-notes.php
