• If the DATABASE_URL starts with postgres:// (Heroku's default), it replaces it with the correct format, postgresql+psycopg2://, making the URI compatible with SQLAlchemy.

Instead of manually replacing the URI, you can use libraries like dj-database-url to parse and adapt the DATABASE_URL for different frameworks or drivers. However, the manual approach is straightforward and works well for most cases.

<?php
// Load WordPress environment
require_once('/path/to/your/wp-load.php');

// Get all posts (any post type)
$args = array(
    'post_type'      => 'any', // 'any' retrieves all post types (posts, pages, custom post types)
    'post_status'    => 'any', // 'any' retrieves all post statuses
    'posts_per_page' => -1,    // Retrieve all posts
);

$all_posts = get_posts($args);

foreach ($all_posts as $post) {
    // Get the post ID
    $post_id = $post->ID;

    // Check if the post has attachments (media files)
    $attachments = get_attached_media('', $post_id);

    // Delete each attachment associated with the post
    foreach ($attachments as $attachment) {
        $attachment_id = $attachment->ID;
        // This deletes the file from the uploads directory and the database record
        wp_delete_attachment($attachment_id, true);
    }

    // Delete the post itself
    wp_delete_post($post_id, true); // true = force delete, bypass trash
}

echo 'All posts and their uploads have been deleted.';

• Backup: Make sure you have a backup of your database and uploads folder before running this script.
• Use on a staging site: Test it on a staging environment before running on a live site, as it will permanently delete all posts and their uploads.

To enable all error debugging in PHP, you can use the following PHP code snippet. This will display all errors, warnings, and notices:

<?php
// Turn on all error reporting
error_reporting(E_ALL);

// Display errors
ini_set('display_errors', 1);

// Optionally, you can log errors instead of displaying them
// ini_set('log_errors', 1);
// ini_set('error_log', '/path/to/php-error.log');

echo "Error reporting is enabled.";
?>
