PHP怎么判斷是否是JSON數(shù)據(jù)

你可以把JSON字符串轉(zhuǎn)成數(shù)組，數(shù)組轉(zhuǎn)過(guò)來(lái)不是數(shù)組那肯定不是JSON數(shù)據(jù)。

php 循環(huán)判斷，判斷json里面的數(shù)據(jù)，大神們幫幫忙啊

$str = '{"queryString":"select id , name from user LIMIT 0, 30 ","data":[{"0":"1","id":"1","1":"aa","name":"aa"},{"0":"2","id":"2","1":"\u5c0f\u4f19\u4f34","name":"\u5c0f\u4f19\u4f34"},{"0":"3","id":"3","1":"\u5c0f\u4f19\u4f34","name":"\u5c0f\u4f19\u4f34"},{"0":"4","id":"4","1":"44","name":"44"},{"0":"5","id":"5","1":"","name":""},{"0":"6","id":"6","1":"","name":""},{"0":"7","id":"7","1":"","name":""},{"0":"8","id":"8","1":"","name":""},{"0":"9","id":"9","1":"","name":""},{"0":"10","id":"10","1":"jiejie","name":"jiejie"},{"0":"11","id":"11","1":"jiejie","name":"jiejie"}]}';

foreach (json_decode($str) as $v)

{

if(is_array($v))

{

foreach($v as $value)

{

echo "當(dāng)前的name 為: {$value-name} id : {$value-id}";

}

}

}

中文不管 你取得是對(duì)應(yīng)的name值

php 判斷是不是json格式

if(!json_decode($json))

{

//不是

}

else

{

//是

}

php怎么判斷一個(gè)字符串是不是json

function?is_not_json($str){??

return?is_null(json_decode($str));

}

function?is_json($string)?{?

json_decode($string);

return?(json_last_error()?==?JSON_ERROR_NONE);

}

如何判斷JSON格式 - PHP進(jìn)階討論

JSON很好識(shí)別的，如果你不確定是否是JSON格式那么你用json_decode對(duì)那個(gè)字符串進(jìn)行解碼判斷，PHP官方對(duì)這個(gè)函數(shù)的返回值的說(shuō)明是：返回值JSON編碼的。值true，false和空（不區(qū)分大小寫(xiě)）返回TRUE，F(xiàn)ALSE和NULL。如果的JSON不能被解碼或者如果編碼的數(shù)據(jù)是深度超過(guò)遞歸限制，則返回NULL。
