How can PHP developers ensure that text is displayed even when neither of the specified GET parameters are present in the URL?

To ensure that text is displayed even when neither of the specified GET parameters are present in the URL, PHP developers can use the isset() function to check if the GET parameters exist. If they do not exist, the developer can then set default values for the parameters and display the text accordingly. 

$param1 = isset($_GET['param1']) ? $_GET['param1'] : 'default_value1';
$param2 = isset($_GET['param2']) ? $_GET['param2'] : 'default_value2';

echo "Parameter 1: " . $param1 . "<br>";
echo "Parameter 2: " . $param2;
