Server side
Usually the HTTP request would point to a dedicated web server page with
scripting capabilities. For example we assume a page called www.server.com/
multilogger.php. On the server side this page would contain some scripting
that decodes the data, checks its contents and store the data into a data
storage. Other webpages can be used to report measurements from this
storage. This document is not intended to be a scripting manual; we refer to
the many help available elsewhere. Please look at the PHP help topic 'varia-
bles from outside PHP' for example. In order to provide a quick start we show
how variables can be evaluated on a PHP page:
<?php
// multilogger.php
// needs 6 arguments, separated by '&':
// The message would be: abcdef&&$d&&$t&&$i&&$v
// argument 0 = 'password' (abcdef)
// argument 1 = $d date // argument 2 = $t time
// argument 3 = $i sensor id
/ argument 4 = $v sensor value
$args = explode ("&", $QUERY_STRING );
$nargs = count($args);
if ($nargs != 5)
{
die();
}
if ($args[0] != "abcdef")
{
die();
}
$date
= urldecode($args[1]) ;
$time
= urldecode($args[2]) ;
$device
= urldecode($args[3]);
$temperature = urldecode($args[4]);
$date = str_replace("'", " ", $date);
$time = str_replace("'", " ", $time);
$device = str_replace("'", " ", $device);
$temperature = str_replace("'", " ", $temperature);
// log it
$db = mysql_connect('server', 'user', 'password');
$result = mysql_select_db('database_name', $db);
$result = mysql_query("delete from temperature where (device ='$device')");
$result = mysql_query("INSERT INTO temperature (logdate, logtime, device, temperature)
VALUES ('$date', '$time', '$device', '$temperature' )", $db);
$result = mysql_close($db);
