How to set custom REQUEST header in PHP

Question

In creating RESPONSE headers, using header() function will do the trick. How about for request headers?

Thanks in advance!

If you are talking about making a request and specifying your headers, one way to do it is using CURL:

$data = "<soap:Envelope>[...]</soap:Envelope>"; 
$tuCurl = curl_init();
curl_setopt($tuCurl, CURLOPT_HEADER, 0);
curl_setopt($tuCurl, CURLOPT_URL, "http://example.com/path/for/soap/url/");
curl_setopt($tuCurl, CURLOPT_POST, 1); // if post request
curl_setopt($tuCurl, CURLOPT_POSTFIELDS, $data);
curl_setopt($tuCurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($tuCurl, CURLOPT_HTTPHEADER, array("Content-Type: text/xml","SOAPAction: \"/soap/action/query\"", "Content-length: ".strlen($data)));
$tuData = curl_exec($tuCurl); 
if(!curl_errno($tuCurl)){ 
  $info = curl_getinfo($tuCurl); 
  echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url']; 
} else { 
  echo 'Curl error: ' . curl_error($tuCurl); 
} 
curl_close($tuCurl); 
echo $tuData;
