What legal considerations should be taken into account when creating online surveys in PHP?

When creating online surveys in PHP, it is important to consider legal requirements such as data protection regulations (e.g., GDPR), ensuring that participants' personal information is stored securely and used appropriately. Additionally, it is crucial to obtain consent from participants before collecting their data and provide them with clear information on how their data will be used. 

// Example code for obtaining consent from participants before collecting data
if(isset($_POST['submit'])){
    $consent = $_POST['consent'];
    
    if($consent == 'agree'){
        // Collect and store participant data
        // Proceed with survey
    } else {
        // Display error message or redirect to a consent page
    }
}
