How can data be sent to an external form (POST) using PHP?

To send data to an external form using PHP, you can use the cURL library which allows you to make HTTP requests. You can use cURL to send a POST request to the external form with the data you want to submit. 

$data = array(
    'key1' => 'value1',
    'key2' => 'value2'
);

$ch = curl_init('http://external-form-url.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$response = curl_exec($ch);

if($response === false){
    echo 'Error: ' . curl_error($ch);
} else {
    echo 'Data sent successfully!';
}

curl_close($ch);
