What are common pitfalls when copying a PHP gallery?

Common pitfalls when copying a PHP gallery include not updating file paths, database connections, and image URLs to match the new environment. To solve this, make sure to carefully update all references to files and databases in the code before running the copied gallery.

// Example code snippet to update file paths and URLs in a copied PHP gallery

// Update file paths
$old_path = '/path/to/old/gallery';
$new_path = '/path/to/new/gallery';

// Update database connection
$old_db_host = 'old_host';
$old_db_user = 'old_user';
$old_db_pass = 'old_pass';
$old_db_name = 'old_db';

$new_db_host = 'new_host';
$new_db_user = 'new_user';
$new_db_pass = 'new_pass';
$new_db_name = 'new_db';

// Update image URLs
$old_image_url = 'http://oldwebsite.com/gallery/images/';
$new_image_url = 'http://newwebsite.com/gallery/images/';
