多層數組和對象轉化的用途很簡單,便於處理WebService中多層數組和對象的轉化
簡單的(array)和(object)只能處理單層的數據,對於多層的數組和對象轉換則無能為力。
通過json_decode(json_encode($object)可以將對象一次性轉換為數組,但是object中遇到非utf-8編碼的非ascii字符則會出現問題,比如gbk的中文,何況json_encode和decode的性能也值得疑慮。
下面上代碼:
復制代碼 代碼如下:
<?php
function objectToArray($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);
?>
