php对json的操作

<?php

header('Content-type:text/html; charset=UTF-8');
$isArray = true;
$jsonData ='[{"Name":"小明","Age":20},{"Name":"小明","Age":20}]';
$jsonArray = json_decode($jsonData,$isArray);
foreach ($jsonArray as $item){
	echo $item['Name'];
}
echo '<br>'.preg_replace("#\\\u([0-9a-f]+)#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\\1'))", json_encode($jsonArray));
?>

 

输出为

小明小明
[{"Name":"小明","Age":20},{"Name":"小明","Age":20}]
