What are some potential pitfalls of using PHP for template classes?

One potential pitfall of using PHP for template classes is the risk of exposing sensitive information if the template file is not properly secured. To prevent this, it is important to sanitize user input and validate data before using it in the template. 

<?php
class Template {
    private $template;

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

    public function render($data) {
        // Sanitize and validate data here before using it in the template
        foreach ($data as $key => $value) {
            $this->template = str_replace("{{" . $key . "}}", $value, $this->template);
        }

        return $this->template;
    }
}

// Example usage
$template = new Template('template.html');
$data = ['name' => 'John Doe', 'email' => 'johndoe@example.com'];
echo $template->render($data);
?>
