<?php
$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echo json_encode($arr);
?>

{"a":1,"b":2,"c":3,"d":4,"e":5}

<?php
$arr = array ('a'=>'芒果小站');
echo json_encode($arr);
?>

$arr = array ('a'=>urlencode('芒果小站'));
echo urldecode(json_encode($arr));以上代码执行后输出：

{"a":"芒果小站"}

，这里分享个更完美的方法：

 /**
  * 不转义中文字符的 json 编码方法
  * @param array $arr 待编码数组
  * @return string
  */
 function encode ($arr) {

  $str = json_encode($arr);
  $search = "#\u([0-9a-f]+)#ie";
  $replace = "iconv('UCS-2', 'UTF-8', pack('H4', '\1'))";

  return preg_replace($search, $replace, $str);

 }
