What could be causing the issue with sorting the Facebook timeline output by date and time in PHP?

The issue with sorting the Facebook timeline output by date and time in PHP could be due to the timestamps being stored in a format that is not easily sortable. To solve this, you can convert the timestamps to Unix timestamp format before sorting them.

// Assuming $posts is an array of Facebook timeline posts with timestamps

// Convert timestamps to Unix timestamp format
foreach ($posts as $post) {
    $post['timestamp'] = strtotime($post['timestamp']);
}

// Sort the posts by timestamp in descending order
usort($posts, function($a, $b) {
    return $b['timestamp'] - $a['timestamp'];
});

// Output the sorted posts
foreach ($posts as $post) {
    echo $post['content'] . ' - ' . date('Y-m-d H:i:s', $post['timestamp']) . '<br>';
}
