What are some potential pitfalls of using eval, include, or require in PHP scripts for template variable replacement?

Using eval, include, or require in PHP scripts for template variable replacement can introduce security vulnerabilities by allowing malicious code execution. To avoid this, it is recommended to use safer alternatives like PHP's built-in string replacement functions or template engines like Twig. 

// Safe variable replacement using PHP's built-in str_replace function
$template = "Hello, {name}!";
$name = "John";
$replacedTemplate = str_replace("{name}", $name, $template);
echo $replacedTemplate;
