What steps should be taken to properly access and edit files in the admin area of a PHP script?

To properly access and edit files in the admin area of a PHP script, you should first ensure that proper authentication and authorization mechanisms are in place to restrict access to only authorized users. Additionally, it is important to sanitize user input to prevent any security vulnerabilities such as SQL injection or cross-site scripting attacks. Finally, consider implementing file permissions and access controls to limit the actions that can be performed on the files. 

// Example code snippet for accessing and editing files in the admin area
if (is_user_authenticated() && is_user_authorized($_SESSION['user_id'])) {
    $file_path = 'admin/files/example.txt';
    
    if (file_exists($file_path)) {
        $file_content = file_get_contents($file_path);
        
        // Edit the file content here
        
        file_put_contents($file_path, $file_content);
        
        echo 'File successfully edited.';
    } else {
        echo 'File not found.';
    }
} else {
    echo 'You are not authorized to access this page.';
}
