What considerations should be made when automatically creating database entries based on file system content in a PHP application, especially in terms of scalability and maintenance?

When automatically creating database entries based on file system content in a PHP application, considerations should be made for scalability and maintenance. It is important to handle potential errors gracefully, such as duplicate entries or missing files. Additionally, implementing proper data validation and sanitization techniques can help prevent security vulnerabilities. Regular maintenance, such as updating file references and database entries, is crucial for long-term scalability. 

// Example PHP code snippet for automatically creating database entries based on file system content

// Specify the directory containing files to process
$directory = '/path/to/files/';

// Get all files in the directory
$files = glob($directory . '*');

// Loop through each file and insert into the database
foreach ($files as $file) {
    $filename = basename($file);
    
    // Check if the file already exists in the database
    $existingFile = $db->query("SELECT * FROM files WHERE filename = '$filename'");
    
    if ($existingFile->num_rows == 0) {
        // Insert file into the database
        $db->query("INSERT INTO files (filename) VALUES ('$filename')");
    } else {
        // Handle duplicate entry or update existing entry
        // This could involve updating metadata or checking for file changes
    }
}
