What potential security risks are associated with using the eval() function in PHP code?

Using the eval() function in PHP code can pose security risks as it allows for the execution of arbitrary code, making the application vulnerable to code injection attacks. To mitigate this risk, it is recommended to avoid using eval() whenever possible and find alternative solutions to dynamic code execution. 

// Avoid using eval() function
$code = $_POST['code'];
// Instead of using eval(), consider using a switch statement or a function mapping approach
switch ($code) {
    case 'case1':
        // Code for case1
        break;
    case 'case2':
        // Code for case2
        break;
    default:
        // Default code
}
