php array 转json及java 转换 json数据格式操作示例
本文实例讲述了phparray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:
phparray转json数据
$arr=array( "demo1"=>"mydemo1", "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":"mydemo1","demo2":{"demo2_demo1":"aaaaaaaa","demo2_demo2":"bbbbbbbb","demo2_demo3":{"demo2_demo3_demo1":"ccccccc"}},"demo3":22}"
array(3){
["demo1"]=>
string(8)"mydemo1"
["demo2"]=>
array(3){
["demo2_demo1"]=>
string(8)"aaaaaaaa"
["demo2_demo2"]=>
string(8)"bbbbbbbb"
["demo2_demo3"]=>
array(1){
["demo2_demo3_demo1"]=>
string(7)"ccccccc"
}
}
["demo3"]=>
int(22)
}

packageMain; publicclassDemo1 { privateStringname; privateintage; publicvoidsetName(Stringname) { this.name=name; } publicStringgetName() { returnthis.name; } publicvoidsetAge(intage) { this.age=age; } publicintgetAge() { returnthis.age; } }
更多关于JSONObject提供的方法JSONArray提供的方法自己探索。
