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. Using a curl call how can I achieve this?

Answer 1

man curl:

       -H/--header 
              (HTTP)  Extra header to use when getting a web page. You may specify
              any number of extra headers. Note that if you should  add  a  custom
              header that has the same name as one of the internal ones curl would
              use, your externally set header will be used instead of the internal
              one.  This  allows  you  to make even trickier stuff than curl would
              normally do. You should not replace internally set  headers  without
              knowing  perfectly well what you're doing. Remove an internal header
              by giving a replacement without content on the  right  side  of  the
              colon, as in: -H "Host:".

              curl  will  make sure that each header you add/replace get sent with
              the proper end of line marker, you should thus not  add  that  as  a
              part  of the header content: do not add newlines or carriage returns
              they will only mess things up for you.

              See also the -A/--user-agent and -e/--referer options.

              This option can be used multiple times to add/replace/remove  multi-
              ple headers.

Answer 2

Use -H or --header.

Answer 3

This is good, but how is it done in php?

Answer 4

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'));
