Accessing data in PHP Object

[nath2098]

Hi there,

 

I'm sending this:

conn.send({"userType":"admin", "userId": <?php echo $_SESSION['userId']; ?>});

and am wondering how to recover it here:

 

public function onMessage(ConnectionInterface $from, $msg) {
        echo sprintf($msg);
        foreach($msg AS $key => $value) {
            echo sprintf($key.": ".$value);
        }
}

The echo $msg returns [object Object] (note the lowercase o then uppercase O, what's that about?) and I get an invalid argument in forEach.

 

Cheers!

"[object Object]" is something created by Javascript, not by PHP. It's what happens when you try to treat an object like a string.

Are you sure conn.send can take any argument type? Or, perhaps, must it be a string value?

Ahh ok, so a string only... I now have it echo sprintf-ing

'userType':'admin', 'userId': '1'

How do I now turn that into an object?

Got it, thanks!

Would be nice to know what answer you found. Can I assume it's JSON.stringify + json_decode?
