What is the potential issue with executing PHP code without user interaction?

Executing PHP code without user interaction can pose a security risk as it opens the door to potential attacks such as code injection or unauthorized access to sensitive information. To mitigate this risk, it is important to validate and sanitize any input data before executing it as PHP code. 

$input_data = $_POST['input_data']; // Assuming input data is received via POST method
$validated_data = validate_input($input_data);

// Function to validate and sanitize input data
function validate_input($input) {
    // Implement your validation and sanitization logic here
    return $validated_data;
}
