Are there alternative methods to executing PHP code stored in variables without using eval()?

Using eval() to execute PHP code stored in variables can be insecure and potentially dangerous. An alternative method to execute PHP code stored in variables is to use the PHP function `create_function()` or `anonymous functions` (also known as closures). These methods provide a safer way to execute dynamic code without the security risks associated with eval(). 

// Using create_function() to execute PHP code stored in a variable
$code = 'echo "Hello, World!";';
$function = create_function('', $code);
$function();

// Using anonymous functions to execute PHP code stored in a variable
$code = 'echo "Hello, World!";';
$function = function() use ($code) {
    eval($code);
};
$function();
