phpjson转数组的例子-PHP源码

$array = array("name" => "Eric","age" => 23);

echo json_encode($array);

程序将打印出 ： {“name”:”Eric”,”age”:23}

$array = array(0 => "Eric", 1 => 23);

echo json_encode($array);

程序将打印出 ：["Eric",23]

$json_arr = array('WebName'=>'PHP网站开发教程网','WebSite'=>'http://www.111cn.net');
$php_json = json_encode($json_arr); //把php数组格式转换成 json 格式的数据
echo $php_json;
$php_json = json_decode($php_json); //再把json格式的数据转换成php数组
print_r($php_json);

json数组

$json = '[{"id":"22","name":"33","descn":"44"}]'; //json格式的数组转换成 php的数组
$arr = (Array)json_decode($json);

echo $arr[0]->id; //用对象的方式访问
