Php/javascript array definition and use---OK in JSON

PHP Array Definition

One-dimensional arrays:

1, $a =array (1,2,4,5,6);

2, $a = Array ("cec" = "Cecvalue", "logo" = "logovalue");

3, $a =["Volvo", "BMW", "SAAB"; PHP 5.4 later version support

4, $cars =[];

$cars [0] = "Volvo";
$cars [1] = "BMW";
$cars [2] = "SAAB";

Differences between two-dimensional arrays:

$a =array (

Array (),

Array ())

Associative arrays:

$a =array (

' A ' =>array (),

' B ' =>array ())

The array definition in JS:

1, var a=[1,2,3,4];

2, var a=new Array ();

3. var a =[[12,3,4,5,5],[1,2,3,4,5]];

4. var china= {beijing:{name: "Beijing", Area: "16000", Haidian:{name: "Haidian"}},

Citation: Alert (China.beijing.haidian.name);

Use in JSON

Php:

Serialize and crossdress using "Json_encode ()" and "Json_decode ()"

Example:

　　　　$a= array(‘a‘ => ‘Apple‘ ,‘b‘ => ‘banana‘ , ‘c‘=> ‘Coconut‘);

　　　　$s= json_encode($a);

echo $s//output result: {"a": "Apple", "B": "Banana", "C": "Coconut"}

　　　　$o= json_decode($s);　　　//反串行化

Js:

Serialize and crossdress using "Json.parse ()" and "Json.stringify ()"

Example:

　　　　var jsonstr = ‘{"name":"jifeng","company":"taobao","value":++value}‘;
　　　　var arrJson arrJSON.parse(jsonstr)                             //反串行化
