How can PHP be used to pass values to an external form using GET method?

To pass values to an external form using the GET method in PHP, you can construct the query string with the values you want to pass and append it to the form's action URL. This way, when the form is submitted, the values will be sent as part of the URL. 

<?php
// Values to pass to the external form
$value1 = "example1";
$value2 = "example2";

// Construct the query string with the values
$queryString = http_build_query(array(
    'param1' => $value1,
    'param2' => $value2
));

// URL of the external form
$externalFormUrl = "http://www.externalform.com/form.php";

// Redirect to the external form with the query string appended
header("Location: $externalFormUrl?$queryString");
exit;
?>
