Parse PHP serialized array in Javascript/jQuery

Question

I have data written to an html file via PHP like so:

$data = json_decode(stripslashes($_POST['data']));

if($data[0]!=''){
    $_SESSION['chatCode'] = $data[2];

    $fp = fopen('../sessions/chats/log_'.$data[2].'.html', 'a');

    $content = array(
        'author' => $data[1],
        'message' => $data[0],
        'time' => date('H:i:s'));

    fwrite($fp,serialize($content));
    fclose($fp);
}

However, I am struggling to parse the serialized data client-side in jQuery. My current code is this:

$.get('sessions/chats/log_'+chatCode+'.html', function(data){
    $('#chatContent').html(makePretty(data));
}

function makePretty(html){
    var data = JSON.stringify(html);

    console.log(data);

    var content = '';

    for(i=0; i < data.length; i++){
        content += '<div class="msgln">'+
            '<div class="meta">'+
                '<span class="name">'+data[i]['author']+'</span>'+
                '<span class="time">'+data[i]['time']+'</span>'+
            '</div>'+
            '<div class="msg">'+data[i]['message']+'</div>'+
        '</div>';
    }

    return content;
}

The log file log_test.html contains:

a:3:{s:6:"author";s:5:"e297f";s:7:"message";s:4:"test";s:4:"time";s:8:"09:23:23";}a:3:{s:6:"author";s:5:"e297f";s:7:"message";s:4:"test";s:4:"time";s:8:"09:26:39";}a:3:{s:6:"author";s:5:"e297f";s:7:"message";s:4:"test";s:4:"time";s:8:"09:37:03";}

The console logs:

"a:3:{s:6:\"author\";s:5:\"e297f\";s:7:\"message\";s:4:\"test\";s:4:\"time\";s:8:\"09:23:23\";}"

The client wanted the logs saved in a local file - it was either html or txt and I've saved logs to html in the past so it seemed the obvious choice. Having second thoughts now! — Ben

Thats because you're serialize($content) data and writing it. Instead try json_encode($content) and write it. That should work with your current jQuery code.

Change

fwrite($fp,serialize($content));

To

fwrite($fp,json_encode($content));

Writing serialized array is bad practice you mush use json_encode for saving data into file:

fwrite($fp,json_encode($content));

and while getting data in ajax, instead of using JSON.stringify use:

JSON.parse(dataString);
