Php json解码更改值

下面是json数组

{"entries":[{"uid":155551338258538,"photo":"https:\/\/m.ak.fbcdn.net\/profile.ak\/hprofile-ak-prn1\/323887_155551338258538_1152153357_q.jpg","type":"user","text":"shikhadamodar","path":"\/shikha.damodar.1","category":"Madiun","names":["shikhadamodar"],"index_rank":-1,"needs_update":true,"non_title_tokens":"madiun"},{"uid":155551332173428,"photo":"https:\/\/m.ak.fbcdn.net\/profile.ak\/hprofile-ak-snc3\/273318_155551332173428_2131571532_q.jpg","type":"user","text":"shreya damodar","path":"\/my.devprofile","category":"Nilai","names":["shreyadamodar"],"index_rank":-1,"needs_update":true,"non_title_tokens":"nilai"},{"uid":155555587232111,"photo":"https:\/\/m.ak.fbcdn.net\/profile.ak\/hprofile-ak-prn1\/41332_155555587232111_3158_q.jpg","type":"user","text":"neha neha","path": "\/neha.neha34","category":"New York, New York","names":["Neha neha"],"index_rank":-1,"needs_update":true,"non_title_tokens":"new york, new york"}],"token":"1333551453-7","display_token":5,"display_ttl":1333541132}

当我解码这个json数组时

array(4){["entries"]=>array(3){[0]=>array(10){["uid"]=>float(1.5555133825854E+14)["photo"]=>string(90) "https://m.ak.fbcdn.net/profile.ak/hprofile-ak-prn1/323887_155551338258538_1152153357_q.jpg"["type"]=>string(4) "user"["text"]=>string(13) "shikhadamodar"["path"]=>string(17) "/shikha.damodar.1"["category"]=>string(6) "Madiun"["names"]=>array(1){[0]=>string(13) "shikhadamodar"}["index_rank"]=>int(-1)["needs_update"]=>bool(true)["non_title_tokens"]=>string(6) "madiun"}[1]=>array(10){["uid"]=>float(1.5555133217343E+14)["photo"]=>string(90) "https://m.ak.fbcdn.net/profile.ak/hprofile-ak-snc3/273318_155551332173428_2131571532_q.jpg"["type"]=>string(4) "user"["text"]=>string(14) "shreya damodar"["path"]=>string(14) "/my.devprofile"["category"]=>string(5) "Nilai"["names"]=>array(1){[0]=>string(13) "shreyadamodar"}["index_rank"]=>int(-1)["needs_update"]=>bool(true)["non_title_tokens"]=>string(5) "nilai"}[2]=>array(10){["uid"]=>float(1.5555558723211E+14)["photo"]=>string(83) "https://m.ak.fbcdn.net/profile.ak/hprofile-ak-prn1/41332_155555587232111_3158_q.jpg"["type"]=>string(4) "user"["text"]=>string(9) "neha neha"["path"]=>string(12) "/neha.neha34"["category"]=>string(18) "New York,New York"["names"]=>array(1){[0]=>string(9) "Neha neha"}["index_rank"]=>int(-1)["needs_update"]=>bool(true)["non_title_tokens"]=>string(18) "new york,new york"}}["token"]=>string(12) "1333551453-7"["display_token"]=>int(5)["display_ttl"]=>int(1333541132)}

json中的第一个UID是

“UID”：155551338258538，

在数组中，它变为

[“uid”]=>float（1.55551338254e+14）

为什么会这样

在获得

1.5555133825854E+14

a reult后，我可以将其更改为真实UID

15555133825838

?

希望一些优秀的程序员能在这方面提供帮助。

我找到了解决您问题的方法。UID字符串很长，因此json_解码正在将其转换为科学符号。试试这个

print_r(json_decode($arr, false,512, JSON_BIGINT_AS_STRING));

你能不能写php代码，你用它来解码json，因为它对我来说工作得很好。是的，没有代码就不能解决这个问题。小数点显然正在移动。你是把它当作替身还是什么？它很有效。。。但是我会输掉比赛的。它每天都变得越来越复杂@钱德雷什_cool@sheryadamodar怎么了？又出什么问题了？哼。。。我不能让它工作。你看过我尝试制作的应用程序吗？我不能聊天，因为我没有名声，我在哪里可以聊天而不是发表评论@钱德雷什：很酷，我还没有做过，但你肯定能帮你走出困境。告诉我现在有什么问题？添加上述代码后，它会抛出一个错误。警告：json_decode（）最多需要3个参数，其中4个参数在--634@chandresh_-cool行中给出
