There are many different traffic analysis tools, ranging from simple counters to complete traffic analyzers. Although there are some free ones, most of them come with a price tag. Why not do it yourself? With PHP, you can easily create a log file within minutes. In this article I will show you how!

Getting the

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product

information

The most important part is getting the information from your visitor. Thankfully, this is extremely easy to do in PHP (or any other scripting language for that matter). PHP has a special global variable called $_SERVER which contains several environment variables, including information about your

// Getting the information

$ipaddress = $_SERVER['REMOTE_ADDR'];

$page = "http://{$_SERVER['HTTP_HOST']}{$_SERVER['PHP_SELF']}";

$page .= iif(!empty($_SERVER['QUERY_STRING']), "?{$_SERVER['QUERY_STRING']}", "");

$referrer =

lude drug-coated devices, drugs packaged with delivery devices in medical kits, and drugs and devices packaged separately but intended to be used together.

$_SERVER['HTTP_REFERER'];

$datetime = mktime();

$useragent = $_SERVER['HTTP_USER_AGENT'];

$remotehost = @getHostByAddr($ipaddress);

As you can see the majority of information comes from the $_SERVER variable. The mktime() (http://nl2.php.net/mktime<

here is enormous increase in the number of combination products entering the market in the recent years. Combination products have proven advantages but fixe

Note: I used a function in the above example called iif(). You can get this

Logging the information

Now that you have all the information you need, it must be written to a log file so you can later look at it, and create useful graphs and charts. To do this you need

The below code will first create a complete line out of all the information. Then it will open the

log file in "Append" mode, and if it doesn't exist yet, create it.

If no errors have occurred, it will write the new logline to the log file, at the bottom, and finally close the log file again.



// Create log line

$logline = $ipaddress . '|' . $referrer . '|' . $datetime . '|' . $useragent . '|' . $re

// Write to log file:

$logfile = '/some/path/to/your/logfile.txt';

// Open the log file in "Append" mode

if (!$handle = fopen($logfile, 'a+')) {

die("Failed to open log file");

}

// Write $logline to our logfile.

if (fwrite($handle, $logline) === FALSE) {

die("Failed to w

rite to log file");

}

fclose($handle);

Now you've got a fully function logging module. To start tracking visitors on your website simply include the logging module into your pages with the include() function (http://www.php.net/include):

ts. Some of the combination products were well accepted by physicians while others suffered. Companies involved in development of combination products are fi

include ('log.php');

Okay, now I want to view my log file

After a while you'll probably want to view your log file. You can easily do so by simply using a standard text editor (like Notepad on Windows) to open the log file, but this is far from desired, because it's in a hard-to-read format.

Let's us

Following aspects would a

e PHP to generate useful overviews for is. The first thing that needs to be done is get the contents from the log file in a variable, like so:



// Open log file

$logfile = "/some/path/to/your/logfile.txt";

if (file_exists($logfile)) {

$handle = fopen($logfile, "r");

$log = fread($handle, filesize($lo

Which markets to tap where the combination products can do fairly well?
Which combination prod

gfile));

fclose($handle);

} else {

die ("The log file doesn't exist!");

}

Now that the log file is in a variable, it's best if each logline is in a separate variable. We can do this using the explode() function (http://www.php.net/explode), lik

Which therapeutic categories to select?
Which Combinations can address unmet needs of the patients?

e so:



// Seperate each logline

$log = explode("
 ", trim($log));

After that it may be useful to get each part of each logline in a separate variable. This can be done by looping through each logline, and using explode again:



// Seperate each part in each logline

t($log); $i++) {

$log[$i] = trim($log[$i]);

$log[$i] = explode('|', $log[$i]);

}

Now the complete log file has been parsed, and we're ready to start generating some interesting stuff.

The first thing that is very easy to do is getting the number of pageviews. Simply use count() (t?

As combination products don't fit into the traditional categories of drugs, medical devices, or biological products, the USFDA is in the process of devel

.phpit.net/count" target="_new">http://www.phpit.net/count) on the $log array, and there you have it;



echo count($log) . " people have visited this website.";

You can also generate a complete overview of your log file, using a simple foreach loop and tables. For example:



// Show a t

';

You can also use custom functions to filter out search engines and crawlers. Or create graphs using PHP/SWF Charts (.

In Conclusion...

In this article I have shown you have to create a logging module for your own PHP website, using nothing more than PHP and its built-in funct

elopment. They need to be wiser in analyzing the market trends and the regulatory requirements.

Companies that provide selfless information through particip
