PHP的JSON解碼奇怪的格式

Question

我正在嘗試從IP警報系統解碼一些數據。 有人告訴我數據是json，通過html文件查看，有對json的引用。 問題是它看起來有點怪:-)

這是警報的原始輸出：

/*-secure- {    senrows : [ {no : "1", type : "Door Contact", zone : "1", name : "zone1", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "2", type : "Door Contact", zone : "2", name : "zone2", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "3", type : "Door Contact", zone : "3", name : "zone3", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "4", type : "Door Contact", zone : "4", name : "zone4", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "5", type : "Door Contact", zone : "5", name : "zone5", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "6", type : "Door Contact", zone : "6", name : "zone6", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "7", type : "Door Contact", zone : "7", name : "zone7", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "8", type : "Door Contact", zone : "8", name : "zone8", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "9", type : "Door Contact", zone : "9", name : "zone9", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "10", type : "IR Sensor", zone : "10", name : "zone10", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "11", type : "Remote Keypad", zone : "11", name : "zone11", attr : "",cond : "", battery : "", tamp : "", bypass : "No"}] } */

如何解碼此數據？ :-)

json_decode（）不起作用：-/

Answer 1

好了，無論誰給您此輸出，您都應該始終首先要求他們修復代碼並實際提供JSON。

仍然，我花了幾分鍾時間，享受了編碼練習，為您的數據編寫了一個快速修復程序。
僅當您的代碼始終以相同的-secure-開頭時，它才起作用，否則您必須對其進行調整。

並且如果由於某種原因您有一個帶有封裝字符串的字段（例如a:"text\\"moretext\\"finaltext" ，或者提供者除示例中顯示的錯誤之外引入了其他錯誤， 它將失敗或產生奇怪的結果。

<?php
$data = /*your not-JSON-string*/;

function fix_botched_json($data) {
    //remove comment-section, we don't need it
    $data = substr($data, 10, strlen($data)-12);
    $seek = '/(\w+)/';
    $exploded = explode('"', $data);
    //explode so we only replace *outside* of strings

    $outside = true;
    foreach($exploded as &$item) {
        if($outside) {
            //the regex matches only word characters.
            $item = preg_replace($seek, '"\1"', $item);
        }
        //alternating between inside and outside of strings
        $outside = !$outside;
    }
    //piece it back together
    $imploded = implode('"', $exploded);

    return $imploded;
}


$final = json_decode(fix_botched_json($data), true);

非常棘手的解決方案，不保證與您可能擁有的其他字符串一起使用。 有很多方法可以處理這種情況，最好的方法可能是要求警報系統的創建者開始生成有效的JSON！

<?php

$string = '/*-secure- {    senrows : [ {no : "1", type : "Door Contact", zone : "1", name : "zone1", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "2", type : "Door Contact", zone : "2", name : "zone2", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "3", type : "Door Contact", zone : "3", name : "zone3", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "4", type : "Door Contact", zone : "4", name : "zone4", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "5", type : "Door Contact", zone : "5", name : "zone5", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "6", type : "Door Contact", zone : "6", name : "zone6", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "7", type : "Door Contact", zone : "7", name : "zone7", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "8", type : "Door Contact", zone : "8", name : "zone8", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "9", type : "Door Contact", zone : "9", name : "zone9", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "10", type : "IR Sensor", zone : "10", name : "zone10", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "11", type : "Remote Keypad", zone : "11", name : "zone11", attr : "",cond : "", battery : "", tamp : "", bypass : "No"}] } */';

function fix_json($st){
    $regex = '/([a-zA-Z0-9_]+)(\s)(?=:)/i';
    return preg_replace($regex, '"$1"', $st);
}

$step1 = strstr($string, '{');
$step2 = rtrim($step1, '*/');


$data = fix_json($step2);

var_dump(json_decode($data, true));
