Are there alternative methods to achieve the same functionality as eval() in PHP without its drawbacks?

Using eval() in PHP can be dangerous as it allows for the execution of arbitrary code, which can lead to security vulnerabilities if not handled properly. One alternative method to achieve similar functionality without the drawbacks of eval() is to use the PHP function `create_function()` or anonymous functions (closures). 

// Using create_function()
$func = create_function('$a, $b', 'return $a + $b;');
echo $func(2, 3); // Output: 5

// Using anonymous functions (closures)
$func = function($a, $b) {
    return $a + $b;
};
echo $func(2, 3); // Output: 5
