How Can I Implement HTTP Basic Authentication with PHP's cURL?

HTTP Basic Authentication with PHP curl

When constructing a REST web service client in PHP, utilizing curl to establish authenticated requests might arise. Implementing HTTP basic authentication requires setting the necessary headers manually.

Solution:

To authenticate a request using HTTP basic, follow these steps:

1. Configure the CURLOPT_USERPWD option:

   curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);

2. Optional: Utilize the Zend HTTP client or a compatible PEAR wrapper for convenience.

Example:

A comprehensive authenticated request could resemble this:

$ch = curl_init($host);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml', $additionalHeaders));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($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);
