What are the potential pitfalls of using the template class provided in the PHP forum thread?

The potential pitfalls of using the template class provided in the PHP forum thread include the lack of error handling, potential security vulnerabilities, and limited customization options. To solve these issues, you can implement error handling, sanitize user inputs to prevent SQL injections, and provide options for customizing the template.

php 
class Template {
    private $template;

    public function __construct($template) {
        $this->template = $template;
    }

    public function render($data) {
        if (!file_exists($this->template)) {
            throw new Exception('Template file not found');
        }

        ob_start();
        extract($data);
        include $this->template;
        return ob_get_clean();
    }
}

// Example usage
$template = new Template('template.php');
$data = ['title' => 'Welcome', 'content' => 'Hello, world!'];
echo $template->render($data);
