// you can reproduce the original variable

//由于 JSON 近年来大受欢迎，PHP5.2 中已经加入了对 JSON 格式的支持。现在你可以使用 json_encode() 和 json_decode() 函数：
 
 
// a complex array
$myvar = array(
 'hello',
 42,
 array(1,'two'),
 'apple'
);
 
// convert to a string
$string = json_encode($myvar);
 
echo $string;
/* prints
["hello",42,[1,"two"],"apple"]
*/
 
// you can reproduce the original variable
$newvar = json_decode($string);
 
print_r($newvar);
/* prints
Array
(
    [0] => hello
    [1] => 42
    [2] => Array
        (
            [0] => 1
            [1] => two
        )
 
    [3] => apple
)
