How to Implement HTTP Basic Authentication with PHP cURL?

HTTP Basic Authentication with PHP cURL

When creating HTTP requests to web services with cURL, you may encounter the need to provide authentication. HTTP basic authentication is a simple method of authenticating users by passing their username and password in the request header. This article demonstrates how to implement HTTP basic authentication using PHP cURL.

Creating the Authentication Header

To authenticate using cURL, you must set the CURLOPT_USERPWD option. This option takes a string in the following format: :. For example:

curl_setopt($ch, CURLOPT_USERPWD, 'user:password');

Setting Additional Request Options

In addition to the authentication header, you may need to specify additional request options, such as:

• CURLOPT_HTTPHEADER: Specify additional headers to send in the request.
• CURLOPT_HEADER: Set to 1 to receive the server's response headers.
• CURLOPT_TIMEOUT: Set the maximum time to wait for the response in seconds.
• CURLOPT_POST: Set to 1 to make a POST request (default is GET).
• CURLOPT_POSTFIELDS: Set the POST data to send in the request.
• CURLOPT_RETURNTRANSFER: Set to TRUE to store the response body as a string.

Example Code

Here's an example script that makes an authenticated request to a web service:

$ch = curl_init($host);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml', 'Additional-Header: value'));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERPWD, 'user:password');
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadName);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$return = curl_exec($ch);
curl_close($ch);
