What are the alternatives to using eval in PHP for dynamic code execution?

Using eval in PHP for dynamic code execution is generally not recommended due to security risks and potential performance issues. Instead, you can use alternative methods such as using anonymous functions, creating dynamic functions, or leveraging PHP's built-in functions for dynamic code execution. 

// Using anonymous functions
$code = 'echo "Hello, World!";';
$func = function() use ($code) { eval($code); };
$func();

// Creating dynamic functions
$code = 'echo "Hello, World!";';
$dynamicFunc = create_function('', $code);
$dynamicFunc();

// Using built-in functions for dynamic code execution
$code = 'echo "Hello, World!";';
$code = '<?php ' . $code . ' ?>';
eval('?>' . $code);
