多层数组和对象转化的用途很简单,便于处理WebService中多层数组和对象的转化
简单的(array)和(object)只能处理单层的数据,对于多层的数组和对象转换则无能为力。
通过json_decode(json_encode($object)可以将对象一次性转换为数组,但是object中遇到非utf-8编码的非ascii字符则会出现问题,比如gbk的中文,何况json_encode和decode的性能也值得疑虑。
下面上代码:
<?php function objectToArray($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); ?>
