How can JavaScript be used to automate form submission in PHP based on the completion of a cURL query?

To automate form submission in PHP based on the completion of a cURL query, you can use JavaScript to trigger the form submission once the cURL query is successful. This can be achieved by making an AJAX request to the PHP script that handles the form submission after the cURL query is completed. The PHP script can then process the form data and submit it accordingly. 

<?php
// Perform cURL query
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// Check if cURL query was successful
if ($response) {
    // Make AJAX request to trigger form submission
    echo '<script>
            var xhr = new XMLHttpRequest();
            xhr.open("POST", "submit_form.php", true);
            xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
            xhr.onreadystatechange = function() {
                if (xhr.readyState === 4 && xhr.status === 200) {
                    console.log("Form submitted successfully");
                }
            };
            xhr.send();
          </script>';
} else {
    echo 'cURL query failed';
}
?>
