When retrieving values from $_GET in PHP, what considerations should be made to ensure accurate data handling and prevent issues like empty or false values?

When retrieving values from $_GET in PHP, it's important to check if the key exists and if the value is not empty or false before using it to prevent issues. This can be done using isset() and !empty() functions in PHP to ensure accurate data handling. 

if(isset($_GET['key']) && !empty($_GET['key'])) {
    $value = $_GET['key'];
    // Use $value safely
} else {
    // Handle the case when the key is empty or not set
}
