问题描述

我们公司使用的可怕系统为我提供了以下输出:

{
    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
    },

我想知道是否有一种方法可以将输出转换为数组，就好像它是一个json一样，或者甚至是某种其他格式，我都可以在PHP中操作此数据. Json_decode不起作用.

解决方案

就像我说的那样，这里是您自己的Json Object解析器.

一个警告，这些事情可能比艺术更像是科学，因此，如果您的输入与示例中的内容有所不同，则可能会出现问题.鉴于样本量很小(1个文档)，因此我无法保证一个示例之外的功能.

我会尝试解释它是如何工作的，但我担心它会在凡人身上丢失.

说真的，这很有趣，一次享受了挑战.

<?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;

您甚至可以在这里进行测试(因为我是个好人)

借助此SO帖子，我能够解决\u00e等编码问题，因此大声疾呼，因为我讨厌字符编码.

伙计，我只是喜欢一段漂亮的代码，只是umm.

干杯！

I would like to know if there is a way to convert the output to array, as if it were a json, or even some other format that I can manipulate this data in PHP. Json_decode does not work.

解决方案

Just like I said I would, here your very own Json Object parser.

One word of warning, these kind of things can be more art then science so if your inputs vary from what was in your example, it could have issues. Given the small sample size (1 document) I make no guarantees on it's functionality outside that one example.

I would try to explain how this works, but I fear it would be lost on mere mortals.

Seriously, this was fun, enjoyed the challenge for once.

    $types = array_keys($tokens);

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

    if (preg_match_all($pattern, $subject, $matches, PREG_OFFSET_CAPTURE)) {
        //print_r($matches);
