reading Response Headers

[ross]

Hi Group,
I am working on web service where I am trying to execute a
remote URL from within a php file and would like to make some
decisions depending on the output.

I am using fopen to open the URL
$handle=@fopen( "www.mysite .com/api/command","r");

If the command is successful it returns an XML file with
response headers. I have no problems reading the XML.

I am interested in the response header which has a session-ID.
how do I access this information.
any inputs are greatly appreciated..
Thanks a bunch,
Regards,
Ross

I guess a socket connection will help you.

By using CURL functions to execute the HTTP query and grab the entire
results.

Here's an exmaple I found and use to get the last modified time of a
remote file:

function filemtime_remot e($uri)
{
$uri = parse_url($uri) ;
$uri['port'] = isset($uri['port']) ? $uri['port'] : 80;

// TimeOut
$tout = 5;
$handle = @fsockopen($uri['host'], $uri['port'], $errno, $errstr,
$tout);
if(!$handle)
return 0;

fputs($handle," HEAD $uri[path] HTTP/1.1\r\nHost: $uri[host]\r\n\r\n");
$result = 0;
while(!feof($ha ndle))
{
$line = fgets($handle,1 024);
if(!trim($line) )
break;

$col = strpos($line,': ');
if($col !== false)
{
$header = trim(substr($li ne,0,$col));
$value = trim(substr($li ne,$col+1));
if(strtolower($ header) == 'last-modified')
{
$result = strtotime($valu e);
break;
}
}
}
fclose($handle) ;
return $result;
}

$URL="http://www.xxxxx.com/filename.txt";
$tsrem = filemtime_remot e($URL);
