note 130141 added to function.array-walk-recursive

If you want to iterate both arrays and objects interchangeably: <?php function array_and_object_walk_recursive(array|object &$array, callable $callback, mixed $arg = null): true { $argumentCount = func_num_args(); if ($argumentCount > 3) { throw new \ArgumentCountError("array_and_object_walk_recursive() expects at most 3 arguments, $argumentCount given"); } $hasThirdArgument = ($argumentCount === 3); foreach ($array as $key => &$value) { if (is_array($value) || is_object($value)) { if ($hasThirdArgument) { array_and_object_walk_recursive($value, $callback, $arg); } else { array_and_object_walk_recursive($value, $callback); } } if ($hasThirdArgument) { ($callback)($value, $key, $arg); } else { ($callback)($value, $key); } } return true; // just mimicking array_walk_recursive } ?> Useful if you have large array-and-object soup in production code. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 62.101.231.203) ---- Manual Page -- https://php.net/manual/en/function.array-walk-recursive.php Edit -- https://main.php.net/note/edit/130141 Del: integrated -- https://main.php.net/note/delete/130141/integrated Del: useless -- https://main.php.net/note/delete/130141/useless Del: bad code -- https://main.php.net/note/delete/130141/bad+code Del: spam -- https://main.php.net/note/delete/130141/spam Del: non-english -- https://main.php.net/note/delete/130141/non-english Del: in docs -- https://main.php.net/note/delete/130141/in+docs Del: other reasons-- https://main.php.net/note/delete/130141 Reject -- https://main.php.net/note/reject/130141 Search -- https://main.php.net/manage/user-notes.php
