How to send a header using a HTTP request through a curl call?

Question

I wish to send a header to my Apache server on a Linux box. How can I achieve this via a curl call?

Answer 1

In PHP:

curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue'));

or you can set multiple:

curl_setopt($ch, CURLOPT_HTTPHEADER, array('HeaderName:HeaderValue', 'HeaderName2:HeaderValue2'));
