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

在执行过程中，这将产生以下结果：

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

<?php
   class Emp {
       public $name = "";
       public $hobbies  = "";
       public $birthdate = "";
   }
   $e = new Emp();
   $e->name = "sachin";
   $e->hobbies  = "sports";
   $e->birthdate = date('m/d/Y h:i:s a', "8/5/1974 12:20:03 p");
   $e->birthdate = date('m/d/Y h:i:s a', strtotime("8/5/1974 12:20:03"));

   echo json_encode($e);
?>

在执行过程中，这将产生以下结果：

{"name":"sachin","hobbies":"sports","birthdate":"08/05/1974 12:20:03 pm"}

<?php
   $json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

   var_dump(json_decode($json));
   var_dump(json_decode($json, true));
?>

在执行过程中，这将产生以下结果：

object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

array(5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

{
 "translation":["Hello world"],
 "query":"你好世界",
 "errorCode":0,

   "key":"你好世界"
  },
  {
   "value":["Hello World"],
   "key":"世界你好"
  }
 ]
}

用json_decode函数返回array的方式得到：

Array
(
 [translation] => Array
  (
   [0] => Hello world
  )
 [query] => 你好世界
 [errorCode] => 0
 [web] => Array
  (
   [0] => Array
    (
     [value] => Array
      (
       [0] => hello world
      )
     [key] => 你好世界
    )
   [1] => Array
    (
     [value] => Array
      (
       [0] => Hello World
      )
     [key] => 世界你好
    )
  )
)

//法一：

//法二：

echo '编码后的json字符串：';
echo $str=json_encode($jarr);//将数组进行json编码
echo '<br>';
