php多层数组和对象的转换

| No Comments | No TrackBacks

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);
?>
