php多層陣列與物件的轉換 3 種實現方式
阿新 • • 發佈:2021-07-17
1. 使用遞迴的方式
// PHP stdClass Object轉array function object_array($array) { if(is_object($array)) { $array = (array)$array; } if(is_array($array)) { foreach($array as $key=>$value) { $array[$key] = object_array($value); } } return$array; }
2. 使用 json_decode(json_encode($object),true)
通過json_decode(json_encode($object)可以將物件一次性轉換為陣列,但是object中遇到非utf-8編碼的非ascii字元則會出現問題,比如gbk的中文,何況json_encode和decode的效能也值得疑慮。
3. 相對而言較完美的解決方案:
<?php function objectToArray($d) { if (is_object($d)) { // Gets the properties of the given object // with get_object_vars function$d = get_object_vars($d); } if (is_array($d)) { /* * Return array converted to object * Using __FUNCTION__ (Magic constant) * for recursive call */ return array_map(__FUNCTION__, $d); } else { // Return array return$d; } } function arrayToObject($d) { if (is_array($d)) { /* * Return array converted to object * Using __FUNCTION__ (Magic constant) * for recursive call */ return (object) array_map(__FUNCTION__, $d); } else { // Return object return $d; } } // Useage: // Create new stdClass Object $init = new stdClass; // Add some test data $init->foo = "Test data"; $init->bar = new stdClass; $init->bar->baaz = "Testing"; $init->bar->fooz = new stdClass; $init->bar->fooz->baz = "Testing again"; $init->foox = "Just test"; // Convert array to object and then object back to array $array = objectToArray($init); $object = arrayToObject($array); // Print objects and array print_r($init); echo "\n"; print_r($array); echo "\n"; print_r($object);
