How can developers ensure that all PHP pages within a project are actively used and maintained?

To ensure that all PHP pages within a project are actively used and maintained, developers can implement a regular code review process where each page is reviewed periodically to check for any outdated or unused code. Additionally, developers can utilize version control systems to track changes made to each page and ensure that they are regularly updated. Automated testing can also be implemented to detect any issues or bugs in the PHP pages.

// Example code snippet for implementing a regular code review process
// This script can be run periodically to check for outdated or unused code in PHP pages

$directory = 'path/to/your/php/pages';
$files = glob($directory . '/*.php');

foreach ($files as $file) {
    // Perform code analysis or checks on each PHP file
    // For example, check for unused functions or outdated syntax
    // Log any issues found for further review
}
