Are there any best practices for using eval in PHP?

Using eval in PHP can be dangerous as it allows for the execution of arbitrary code, opening up the possibility of code injection attacks. It is recommended to avoid using eval whenever possible. If you must use eval, make sure to sanitize and validate the input to prevent any potentially harmful code from being executed. 

$input = "echo 'Hello, World!';";
if (/* validate input */) {
    eval($input);
}
