将结构转换为 PHP 数组

Question

我们公司使用的可怕系统给我以下输出：

{
    party:"bases",
    number:"1",
    id:"xx_3039366",
    url:"systen01-ny.com",
    target:"_self",
    address:"Ch\u00e3o as Alminhas-Medas,Uteiros de Gatos e Fontes Longaq<br/>64320-761 ANHADOS LdA",
    coordinate:{
        x:90.995262145996094,
        y:-1.3394836426
    },
    contactDetails:{
        id:"366",
        phone:"xxxxxx",
        mobile:"",
        fax:"xxxx 777 235",
        c2c:!0
    },
    parameters:"Flex Am\u00e1vel Silva,hal,,EN_30336,S,786657,1,0,",
    text:"Vila Nova de Loz C\u00f4a,os melhores vinhos, v\u00e1rias. Produtor/exportador/com\u00e9rcio",
    website:null,
    mail:"",
    listing:"paid",
    pCode:"64",
    name:"xpto Am\u00e1vel Costa",
    logo:{src:"http://ny.test.gif",
    altname:"xpto Am\u00e1vel Costa"},
    bookingUrl:"",
    ipUrl:"",
    ipLabel:"",
    customerId:"7657",
    addressId:"98760",
    combined:null,
    showReviews:!0
}

我想知道是否有办法将输出转换为数组，就好像它是一个 json，或者我可以在 PHP 中操作这些数据的其他格式. Json_decode 无效。

Answer 1

就像我说的那样，这里是您自己的 Json 对象解析器。

提醒一句，这类事情可能更像是艺术而不是科学，因此如果您的输入与示例中的不同，则可能会出现问题。鉴于样本量较小（1 个文档），我不保证它在该示例之外的功能。

我会尝试解释它是如何工作的，但我担心它会被凡人所迷失。

说真的，这很有趣，享受一次挑战。

<?php
function parseJson($subject, $tokens)
{
    $types = array_keys($tokens);
    $patterns = [];
    $lexer_stream = [];

    $result = false;

    foreach ($tokens as $k=>$v){
        $patterns[] = "(?P<$k>$v)";      
    } 
    $pattern = "/".implode('|', $patterns)."/i";

    if (preg_match_all($pattern, $subject, $matches, PREG_OFFSET_CAPTURE)) {
        //print_r($matches);
        foreach ($matches[0] as $key => $value) {
            $match = [];
            foreach ($types as $type) {
                $match = $matches[$type][$key];
                if (is_array($match) && $match[1] != -1) {
                    break;
                }
            }

            $tok  = [
                'content' => $match[0],
                'type' => $type,
                'offset' => $match[1]
            ];

            $lexer_stream[] = $tok;       
        }

       $result = parseJsonTokens( $lexer_stream );

你甚至可以在这里测试它（因为我是个好人）

在这个 SO post 的帮助下，我能够解决编码问题 \u00e 等问题，所以向他们大声疾呼，因为我讨厌字符编码。

伙计，我只是喜欢一段漂亮的代码，嗯。

干杯！
