每日总结

1.今天重新开始php，JSON

PHP 数组转换为 JSON 格式数据：

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


?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);

?>

解码 JSON 数据：

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

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