http Headers / status

davieboy

am using

$fp = fsockopen("$device_id", 80, $errno, $errstr, 5);
if (!$fp) {
   echo "$errstr ($errno)<br />\n";
} else {
$post = 
"HEAD $device_id HTTP/1.0\n\n" .
"HOST: $device_id<br><br>".
"\n" .
"$data\n\n";
"Host: $device_id\n";
$check = fputs($fp, $post);
$array = explode (" ", $data); 
    	echo $array[0]; 
$response = fgets($fp, 128);
$array = explode (" ", $response); 
    	echo "Status Code: " .$array[1]."<br />";
		echo "Text: " .$array[2]." ".$array[3]."<br />"; 

}

to check the header status of the server ($device_id)

problem is it contantly giving me 400 Bad Request errors

Anyone see y?

What does $device_id contain? It is a URL or a hostname?

Here:
"HEAD $device_id HTTP/1.0\n\n" .
"HOST: $device_id<br><br>".
"\n" .
"$data\n\n";
"Host: $device_id\n";

You are using $device_id both as a URL (in the HEAD part) and as a host name (in the Host part). Also, you have HOST and Host; you should just use Host immediately after HEAD. Also, you're saying HTTP/1.0, but Host is new in HTTP/1.1. And you've got an extra newline after HEAD. And you're using <br> which is wrong; HTTP is not HTML.

I think it should probably look more like this:

$url = 'http://www.example.com/somepage.html';
$host = 'www.example.com';
$request = "HEAD $url HTTP/1.1\nHost: $host\n\n";

davieboy

the device id

is in the url and is in the form of

<?php
$device_id = $_GET['device_id'];
?>

davieboy

The first half of the first example shows how to time an operation (in the example, a 1000 iteration loop).
