What are the potential risks of using the eval() function in PHP, as mentioned in the forum thread responses?

The potential risks of using the eval() function in PHP include security vulnerabilities such as code injection attacks and performance issues. It is recommended to avoid using eval() whenever possible and find alternative solutions to dynamically execute code. 

// Avoid using eval() function
$code = "echo 'Hello, World!';";
eval($code); // Avoid using eval() function

// Alternative solution using anonymous functions
$func = function() {
    echo 'Hello, World!';
};
$func(); // Outputs: Hello, World!
