How can PHP developers ensure that the values passed through a form using the GET method are correctly received and processed in subsequent pages or iframes?

When passing values through a form using the GET method, PHP developers can ensure that the values are correctly received and processed by accessing them through the $_GET superglobal array. This array contains key-value pairs of all the parameters passed through the URL. By accessing the values using the keys provided in the form, developers can ensure that the data is correctly processed in subsequent pages or iframes. 

// Accessing values passed through a form using the GET method
$value1 = $_GET['key1'];
$value2 = $_GET['key2'];

// Process the values as needed
// For example, echoing them out
echo "Value 1: " . $value1 . "<br>";
echo "Value 2: " . $value2;
