What alternative approaches can be used to achieve the same functionality as the eval() function in PHP without risking parse errors?

Using eval() function in PHP can be risky as it allows for the execution of arbitrary code, which can lead to security vulnerabilities and parse errors if not handled properly. To achieve the same functionality without risking parse errors, alternative approaches such as using anonymous functions or the use of the create_function() function can be used.

// Using anonymous functions to achieve the same functionality as eval()
$code = '$a = 5; $b = 10; return $a + $b;';
$addition = function() use ($code) {
    return eval($code);
};
echo $addition();

// Using create_function() to achieve the same functionality as eval()
$code = '$a = 5; $b = 10; return $a + $b;';
$addition = create_function('', $code);
echo $addition();
