Users Online

Daniel — Thu, 27 Jul 2006 02:05:19 +0000

Keeping track of how many users have been on your website is very easy. This can be done with some basic MySQL code and the date() function. All you have to do is keep track of the users IP address and time they were last on the page. Lets get to some code:

$server = 'localhost';
$user = 'root';
$pass = '';
$db2 = 'online';

$db = mysql_connect($server, $user, $pass) or die("Could not connect.");
if(!$db) 
	die("no db");
if(!mysql_select_db("$db2",$db))
 	die("No database selected.");
$server_time=date("U");
$client_ip=$_SERVER['REMOTE_ADDR'];

$query = mysql_query("SELECT * FROM current_users WHERE ip='$client_ip'");
$check = mysql_fetch_array($query);
if($check) {
	$update="UPDATE current_users set time='$server_time' where ip='$check[ip]'";
	mysql_query($update) or die("Unable to process update: " . mysql_error());
} else {
  $sql = "INSERT INTO `current_users` (`ip`, `time`) VALUES ('$client_ip', '$server_time')";
  $result = mysql_query($sql) or die("Unable to process insert: " . mysql_error());
}
$time=$server_time-1800;
$remove = "DELETE from current_users WHERE time<'$time'"; // Remove users outside time limit
mysql_query($remove) or die("Unable to delete: " . mysql_error());

// Show the count
$sql2 = mysql_query("SELECT ip FROM current_users" );
$currentVisitors = mysql_num_rows($sql2);
echo 'There have been '.$currentVisitors.' users online in the last 30 minuets.';
?>

The first query checks to see if your IP address is in the database. If your IP address is in the database it updates the time. If your IP address is not in the database, we then insert the time and your IP address.

To eliminate old users we automatically remove users who have been online after 30 minutes(1800 Seconds). If you want to change the time delay just multiply 60 times the number of minutes.
10 Minutes = 600
15 Minutes = 900
20 Minutes = 1200
30 Minutes = 1800
1 Hour = 3600

Make sure you create a database and apply your settings to the variables at the top.
Insert the following SQL query into your database:

CREATE TABLE `current_users` (
`ip` varchar(30) NOT NULL default ”,
`time` varchar(30) NOT NULL default ”
) TYPE=MyISAM;

Just save this as online.php and include this in your page.

Flat file hit counter with image display

If you liked the flat file hit counter tutorial, this is a little more advanced. This uses the same basic concept for counting and writing the hits, but is different in showing hits. Use the following code:

$file = "hits.dat"; // Hit count file
$fp = @fopen($file, "r"); // Open hits in readonly
$count = @fread($fp, filesize($file)); // get hits

@fclose($fp); // close file
if($count) {
  $count++; // Add 1 to hits if hits exist
} else {
  $count = 1; // If no hits make hits1
}
$fp = fopen($file, "w"); // Open file for writing

@fputs($fp, $count); // Write hits

@fclose($fp); // close file
for($i=0;$i<strlen($count);$i++) {
  $img = substr($count,$i,1); // Get next image
  $hits .= "$img.gif'>";
}
echo $hits;
?>

If you want to just display the hits without counting them use the following code:

$file = "hits.dat"; // Hit count file
$fp = @fopen($file, "r"); // Open hits in readonly
$count = @fread($fp, filesize($file)); // get hits

@fclose($fp); // close file
for($i=0;$i<strlen($count);$i++) {
  $img = substr($count,$i,1); // Get next image
  $hits .= "$img.gif'>";
}
echo $hits;
?>

Please make sure that your hits.dat file is chmoded to 666, which is all read and write permissions.

You can get as creative as you like with the images used in showing your hits. If you need some basic images you can use the following images:

Flat file hit counter

Daniel — Fri, 14 Jul 2006 13:38:37 +0000

So you need to track hits to your website but don’t want to use a database or don’t have access to a database server. You can still do this by using a flat file on your server. Copy the following code to your website where you want to show/count the hits.

$file = 'hits.dat'; // File where data is stored
$fp = fopen($file, "r");  // Open file as read only
$count = fread ($fp, filesize($file)); // Read hits
fclose($fp); // Close file
$count++; // Add 1 to the count
$fp = fopen($file, "w"); // Open file for writing
fwrite($fp, $count); // Write the count
fclose($fp); // Close file
echo "Load $count times";
?>

If you wanted to only show the code without updating the hits use the following code:

$file = 'hits.dat'; // File where data is stored
$fp = fopen($file, "r");  // Open file as read only
$count = fread ($fp, filesize($file)); // Read hits
fclose($fp); // Close file
echo "Load $count times";
?>

Please note that the hits.dat or the file in the $file variable must be chmoded to atleast 666 or be read and writable.

Create a MySQL hit counter

Daniel — Fri, 14 Jul 2006 13:36:57 +0000

So you want to keep track of your website hits in a database. Using the following code this is possible. Lets start.

Create a blank database on your server. Now using a database manager like phpmyadmin, add the following sql into the database:

CREATE TABLE `hit_count` (
`hits` int(50) NOT NULL default ‘0′
) TYPE=MyISAM;

INSERT INTO `hit_count` VALUES (0);

Next create a blank document on your computer using your favorite editor and past the following into that file:

// DB Settings
$server = 'localhost';
$user = '';
$pass = '';
$db2 = '';

$db = mysql_connect("$server", "$user", "$pass") or die("Could not connect.");
if(!$db)
die("no db");
if(!mysql_select_db("$db2",$db))
die("No database selected.");

?>

Add your username to MySQL between the ‘ ‘ in the $user = ”;.

Add your password to MySQL to the $pass and your database name to the $db2.

Now after:

die("No database selected.");

But before:

?>

Add the following code:

$query1 = mysql_query("SELECT hits FROM hit_count");// Get hit count
$total = mysql_fetch_array($query1);

$hitCount = $total['hits'] + 1;// Add 1 to the count

$sql = "UPDATE `hit_count` SET `hits` = '$hitCount'"; // Update Hits
mysql_query($sql) or die("Unable to process query: " . mysql_error());

echo 'Hits: '.$hitCount; // Show hits

Thats all there is to creating a hit counter and showing the results on your page.

If you want to show the hits on a page without updating them you can use the following code:

$total = mysql_fetch_array($query);
echo 'Total Hits: '.$total['hits'];
?>

Make sure that you connect to the database before you call the above code.
