php array 转json及java 转换 json数据格式操作示例

本文实例讲述了php array 转json及java 转换 json数据格式操作。分享给大家供大家参考，具体如下：

php array 转json白狗秋千架 数据

$arr = array(  "demo1" => "my demo1",  "demo2" => array(    "demo2_demo1"=>"aaaaaaaa",    "demo2_demo2"=>"bbbbbbbb",     "demo2_demo3"=>array(      "demo2_demo3_demo1"=>"ccccccc"    )  ),  "demo3" => 22);$json_str = json_encode($arr,true);$arr = json_decode($json_str,true);var_dump($json_str);var_dump($arr);//查看结果

运行结果：

string(137) “{“demo1″:”my demo1″,”demo2”:{“demo2_demo1″:”aaaaaaaa”,”demo2_demo2″:”bbbbbbbb”,”demo2_demo3″:{“demo2_demo3_demo1″:”ccccccc”}},”demo3″:22}”
array(3) {
[“demo1”]=>
string(8) “my demo1”
[“demo2”]=>
array(3) {
[“demo2_demo1”]=>

[“demo2_demo2”]=>
string(8) “bbbbbbbb”
[“demo2_demo3”]=>
array(1) {
[“demo2_demo3_demo1”]梦见别人给钱=>
string(7) “ccccccc”
}
}
[“demo3”]=>
int(22)
}
