Thread: Cannot Use Object of Type stdClass as Array

Fatal error: Cannot use object of type stdClass as array in **/index.php on line 18

The code was working fine recently, but now, I suspect due to a PHP upgrade, is rendering the above referenced error message. I'm not really sure how to rectify something such as this, so any help would be greatly appreciated so I can get things running once again.

Line 18 is within the below code, it begins with "$first_tweet."

PHP Code:

<?php
    if(isset($_POST['firstuser'])) {
        $first_user = $_POST['firstuser'];
        $twitter = new Twitter($requestusername, $requestpassword);
        $user1errorstatus = false;
        $results = false;
        $user_first_info = json_decode($twitter->showUser("json", $first_user));
        if(isset($user_first_info->error)) {
            $user1errorstatus = true;
        }
        if($user1errorstatus == false) {
            $num_tweets = $user_first_info->statuses_count;
            $inpage = ceil($num_tweets / 20);
            $userstats = $twitter->getUserTimeline($first_user, $inpage);
            $userstats = json_decode($userstats);
            $num_stats = count($userstats) - 1;
            $first_tweet = $userstats[$num_stats]->text;
            $results = true;
        }
    }
?>

Did you try dumping the array? No idea why a $_POST would have a object in it, but it could somehow have gotten one in it causing it to do that.

It's probably trying to do like $_POST[0]->firstuser; That's what that error usually refers to.

Both could be some use to help you fix the error.

This error means that $userstats is not an array but an object so you have to use different notation to access it's elements i.e.
$first_tweet = $userstats->$num_stats->text;

Using print_r($userstats); and viewing the page source should reveal it's properties.

Alright, so I changed that line to:
$first_tweet = $userstats->$num_stats->text;

Now, the first tweet isn't showing. Was there something else I needed to change, or would this be the result of another issue entirely?

I guess it is due to some other problem such as the $userstats not containing useful data.

After the line $userstats = json_decode($userstats);

$userstats may well contain an error message rather than an array of results.

Following that line with print_r($userstats); should reveal what it consists of.

The print_r statement is very useful for this purpose.

It seems you aren't accessing the desired member variable correctly.

Can you paste a part of the output you get for the print_r($userstats); statement?

That'll have some interesting information.
