How can arrays be used to send data via POST in PHP?

To send data via POST in PHP using arrays, you can construct an associative array where the keys represent the form field names and the values represent the data to be sent. You can then use the `http_build_query()` function to encode the array into a URL-encoded query string, which can be sent in the body of the POST request. 

// Construct an associative array with form field names and data
$data = array(
    'username' => 'john_doe',
    'email' => 'john.doe@example.com',
    'password' => 'password123'
);

// Encode the array into a URL-encoded query string
$postData = http_build_query($data);

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

// Set cURL options to send a POST request with the encoded data
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);

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

// Close the cURL session
curl_close($ch);

// Handle the response data as needed
echo $response;
