What are the advantages and disadvantages of using fsockopen() or cURL for sending POST requests in PHP?

When sending POST requests in PHP, both fsockopen() and cURL are commonly used methods. Advantages of using fsockopen(): - Lower level control over the request and response headers - Can be more lightweight and faster for simple requests Disadvantages of using fsockopen(): - Requires more manual handling of the request and response data - Limited built-in functionality compared to cURL Advantages of using cURL: - Higher level of abstraction with built-in functions for handling requests and responses - Supports a wide range of protocols and options for customization Disadvantages of using cURL: - Can be slower and heavier than fsockopen for simple requests - Requires the cURL extension to be installed on the server Here is a PHP code snippet using cURL to send a POST request: 

$url = 'https://example.com/api';
$data = array('key1' => 'value1', 'key2' => 'value2');

$ch = curl_init($url);
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 'Response: ' . $response;
}

curl_close($ch);
