Receiving data via TCP/IP HTTP/GET

dhopkins

I'm trying to retreive information from an HTML free web page that consists of a simple ASCII string of pipe-delimited data.

The monitor is running on an internal web serber, listening for TCP/IP HTTP/GEt requests on Port 80. I'm trying to access it from a remote server.

The data returned from the server address is:
Cabinet 1|88.2|Cabinet 2|87.6|Cabinet 3|84.3|AC Output Temp.|66.5

I'm trying to get the data and dump it in a database.

Thank you.

Check out [man]curl[/man]. There's a lot of script tidbits on php.net. You can give Curl the URL and it'll return the contents. Then you can just explode on the | and then store the data...

Here's some code you can use:


$server='www.geotekcs.co.uk';
$port=80;

$get='/'; # get default index page

$socket=fsockopen($server, $port) or die("Unable to connect to $server on $port.");

fputs($socket, "GET $get HTTP/1.0\r\n\r\n");

while (!feof($socket)) {
  @$data.= fgets($socket, 4096);
}

fclose($socket);

print "Here is the data: $data";

Hope this helps.

Cheers.

Thanks AstroTeg and w.geoghegan. I was able to use the w.geoghegan solution successfully. cURL may have done the trick, but I didn't have time and it looked a little much for my simple problem.

I'm not normally into spoon-feeding code, but to show how easy Curl is:

$url = 'http://[your url]';
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);				// allows us to capture the HTML
$result = curl_exec($curl);
curl_close ($curl);

// $result will contain the HTML output of the $url page.

Curl handles all the heavy lifting of dealing with sockets.
