How can multiple variables be sent to another server in PHP without using multiple form submissions?

When sending multiple variables to another server in PHP without using multiple form submissions, you can use techniques like serializing the data into a single string or JSON object before sending it. This way, you can send all the variables in a single request to the server. 

// Serialize the variables into a single string
$data = array(
    'variable1' => $variable1,
    'variable2' => $variable2,
    'variable3' => $variable3
);

$serialized_data = http_build_query($data);

// Send the data to the server
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/endpoint');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $serialized_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

curl_close($ch);

// Handle the response from the server
echo $response;
