如何在Javascript中反序列化数组

I have arrays stored in files which have been serialized in php so that I don't have to explode/implode every time I use the data.
Is there a way by which i can unserialize and add a dimension to it in JS ?

the php equivalent would look like

$key = $_POST['num'];
$array = unserialize(file_get_contents("file.data");
$array[$key][0] = "marked";
file_put_contents(serialize($array);  

the array $key[0] does not yet exist but i don't know if it will affect the rest of the the code

图片转代码服务由CSDN问答提供 功能建议

我将数组存储在已经在php中序列化的文件中,这样我就不必每次都爆炸/内爆 时间我使用数据。
有哪种方法可以反序列化并在JS中添加维度?

php等价物看起来像

  $ key = $ _POST ['num']; \  n $ array = unserialize(file_get_contents(“file.data”); 
 $ array [$ key] [0] =“marked”; 
file_put_contents(serialize($ array); 
    
 
 

数组 $ key [0] 尚不存在,但我不知道它是否会影响代码的其余部分

    For javascript you probably don't want to use serialize and unserialize, but instead turn the result into JSON with json_encode.

    This format can be easily decoded by Javascript using JSON.parse().

    Unserilized your data using PHP unserialize function. And put convert it Json by using PHP Json_encode Encode function.

    <script>
    var data = JSON.parse('<?php echo json_encode(unserialize(file_get_content('filename.txt'))); ?>');
    </script>
