What potential pitfalls should be considered when automatically generating subpages in PHP?

When automatically generating subpages in PHP, potential pitfalls to consider include security vulnerabilities such as injection attacks if user input is not properly sanitized, potential performance issues if the generation process is resource-intensive, and the risk of creating duplicate or conflicting subpages if not managed carefully. To mitigate these risks, always sanitize user input to prevent injection attacks, optimize the generation process to avoid performance bottlenecks, and implement a mechanism to check for existing subpages before creating new ones. 

// Sanitize user input
$subpageName = filter_var($_POST['subpage_name'], FILTER_SANITIZE_STRING);

// Check for existing subpage before creating new one
if (!file_exists("subpages/{$subpageName}.php")) {
    // Generate subpage content and save to file
    $content = "<html><body><h1>{$subpageName}</h1></body></html>";
    file_put_contents("subpages/{$subpageName}.php", $content);
    echo "Subpage {$subpageName} created successfully!";
} else {
    echo "Subpage {$subpageName} already exists.";
}
