note 130001 added to function.in-array

If you need to provide an array of values ​​to be searched for in the values ​​of another array, or even in the keys of another array, this possibility does not exist natively in PHP, but if we use the str_replace() function cleverly we can achieve this goal. function any_in_array(array $needle, array $haystack, string $where = 'keys'): bool { if ($where == 'keys') { $invoke = 'array_keys'; } else if ($where == 'values') { $invoke = 'array_values'; } else { return false; } str_replace($needle, '', implode('¬¬', $invoke($haystack)), $occurrences); return $occurrences > 0; } var_dump(any_in_array(['abc', 'PHP_SELF', 'def'], $_SERVER, 'keys')); // bool(true) print_r($_SERVER); ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.84.18 (proxied: 191.184.0.28) ---- Manual Page -- https://php.net/manual/en/function.in-array.php Edit -- https://main.php.net/note/edit/130001 Del: integrated -- https://main.php.net/note/delete/130001/integrated Del: useless -- https://main.php.net/note/delete/130001/useless Del: bad code -- https://main.php.net/note/delete/130001/bad+code Del: spam -- https://main.php.net/note/delete/130001/spam Del: non-english -- https://main.php.net/note/delete/130001/non-english Del: in docs -- https://main.php.net/note/delete/130001/in+docs Del: other reasons-- https://main.php.net/note/delete/130001 Reject -- https://main.php.net/note/reject/130001 Search -- https://main.php.net/manage/user-notes.php
