直接使用PHP的json_decode报错

解决思路：
1、手动格式化，将所有","换行
2、半分法删除内容定位报错的代码行
3、找到问题行后过滤格式处理
4、对于json格式中掺杂了javascript代码的情况还可以直接使用v8js引擎处理

解决方案一（修复格式）：

$str = file_get_contents(‘test.txt’);

KaTeX parse error: Undefined control sequence: \* at position 23: …reg_replace('@/\̲*̲[^/]+\*/@isU','…str);

$str=st{r}_{r}eplace{(}^{\prime }"+document.location.hostnam{e}^{\prime }{,}^{\prime }{"}^{\prime },$str);

$str=st{r}_{r}eplace{(}^{\prime }"1"=="1{"}^{\prime }{,}^{\prime }tru{e}^{\prime },$str);

$json=jso{n}_{d}ecode($str);

if(!$json) $json=json2array($str);

var_dump(getJsJSON($json));

解决方案二(使用PHP-V8JS扩展)：

//以JavaScript环境执行JS
function getJsJSON($str){
$v8 = new V8Js();
KaTeX parse error: Expected '}', got 'EOF' at end of input: …}} a={str}
return JSON.stringify(a);
}
b = getJsJSON()

";

try {
//传递参数给js
// $v8->str = $str;
//执行js
$code = $v8->executeString($func);
//清空对象，垃圾回收。
unset($v8);
} catch (V8JsScriptException KaTeX parse error: Expected '}', got 'EOF' at end of input: … dump(e->getMessage());
dump($e->getJsSourceLine());dump($e->getJsTrace());
// dump(KaTeX parse error: Expected 'EOF', got '}' at position 11: e); }̲ if(code)$code=jso{n}_{d}ecode($code,true);
return $code;
}

$js=fil{e}_{g}e{t}_{c}ontents{(}^{\prime }test.tx{t}^{\prime });va{r}_{d}ump(getJsJSON($js));
