How can a PHP beginner effectively pass variable values to an external PHP script for submission?

To pass variable values to an external PHP script for submission, you can use the cURL library in PHP. This allows you to make HTTP requests to the external script with the necessary data included in the request. You can send the variables as POST data using cURL to effectively pass them to the external script.

<?php

// Data to be passed to the external script
$data = array(
    'variable1' => 'value1',
    'variable2' => 'value2'
);

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://external-script-url.com');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Handle response from external script
echo $response;

?>
