Are there common issues with PHP code that can lead to inconsistent display order of postings in web applications?

One common issue that can lead to inconsistent display order of postings in web applications is not sorting the data properly before displaying it. To solve this issue, you should make sure to sort the data based on a consistent criteria, such as the posting date or ID, before displaying it.

// Assuming $postings is an array of posting data
usort($postings, function($a, $b) {
    return strtotime($b['posting_date']) - strtotime($a['posting_date']);
});

foreach ($postings as $posting) {
    // Display the posting data
}
