this is a flat unique ip counter. it writes to two files you will have to make "ips.txt" "logipdates.txt" it uses a loop to count the ips from the ips.txt file. The logipdates.txt is for putting a date and time to the ip hits.

[html]<?php $file = "C:/yoursite/text/ips.txt";
$logdate = "C:/yoursite/text/logipdates.txt";
$today = date (" m,d,Y,g:ia");

// Obtain users IP address
$getip = getenv(REMOTE_ADDR);
$addip = "TRUE";
$count = 0;

// Open $file and search each line (IP address) for a match
$fpip = fopen($file,"r");
while (!feof($fpip))
{
$line = fgets($fpip, 4096); //gets one line at a time
$line=trim($line);
if ($line != "")
{
$count++;
}
}

// If IP is already logged
if ($line==$getip)
{
$addip = "FALSE";
}
{
fclose($fpip);
}

// If the IP was not previously logged, append it to $file
if ($addip == "TRUE")
{
$fpip = fopen($file,"a");
fwrite($fpip, "\n");
fwrite($fpip, $getip);
fclose($fpip);
$count++;
$fpd = fopen($logdate, "a");
fwrite($fpdate, "\n");
fwrite($fpdate, $ipadd);
fwrite($fpdate, $today);
fclose($fpdate);
}

// Display count
echo $count;
readfile ("$logdate");
?>[/html]

Getting Started

Create a file named hello.php and put it in your web server's root directory (DOCUMENT_ROOT) with the following content:

Code: Select all

<html>
 <head>
  <title>[color=green]PAGE TITLE[/color] </title>
 </head>
 <body>
 <?php echo '<p>Hello World</p>'; ?>
</body>
</html>

Use your browser to access the file with your web server's URL, ending with the "/hello.php" file reference. When developing locally this URL will be something like [url="http://localhost/hello.php"]http://localhost/hello.php[/url] or [url="http://127.0.0.1/hello.php"]http://127.0.0.1/hello.php[/url] but this depends on the web server's configuration. Although this is outside the scope of this tutorial, see also the DocumentRoot and ServerName directives in your web server's configuration file (for Apache, this is httpd.conf). If everything is configured correctly, this file will be parsed by PHP and the following output will be sent to your browser:

Code: Select all

<html>
 <head>
  <title>PHP Test</title>
 </head>
 <body>
 <p>Hello World</p>
 </body>
</html>

Forms

Code: Select all

<form action="action.php" method="post">
 Your name: <input type="text" name="name" />
 Your age: <input type="text" name="age" />
 <input type="submit" />
</form>

There is nothing special about this form. It is a straight HTML form with no special tags of any kind. When the user fills in this form and hits the submit button, the action.php page is called. In this file you would write something like this:

Code: Select all

Hi <?php echo $_POST['name']; ?>.
You are <?php echo $_POST['age']; ?> years old.

Then the script should show:

Hi Danny. You are 14 years old.

It should be obvious what this does. There is nothing more to it. The $_POST['name'] and $_POST['age'] variables are automatically set for you by PHP. Earlier we used the $_SERVER autoglobal; above we just introduced the $_POST autoglobal which contains all POST data. Notice how the method of our form is POST. If we used the method GET then our form information would live in the $_GET autoglobal instead. You may also use the $_REQUEST autoglobal, if you do not care about the source of your request data. It contains the merged information of GET, POST and COOKIE data.

I tried some of RuffRyders codes, the Unique ID, and Display Visitors IP, but couldnt get them to work. Ive not done any PHP before some Im a total newb. I tried putting them in the head, and body of my pages and neither worked. Any help would be great

Thanks

Try this..

Code: Select all

<html>
<head>
<title>PHPness</title>
</head>
<body>
<?
if(getenv(HTTP_CLIENT_IP)) { 
          $_ip = getenv(HTTP_CLIENT_IP); 
} 
elseif(getenv(HTTP_X_FORWARDED_FOR)) { 
          $_ip = getenv(HTTP_X_FORWARDED_FOR); 
} 
else { 
          $_ip = $REMOTE_ADDR; 
}
echo "Your IP: ".$_ip.".";
echo "Unique ID: ".$_SERVER['UNIQUE_ID'].".";
?>
</body>
</html>

Also.. are you running these on a PHP enabled server? Silly question I know, but you can't run it locally without speciallist software installed.

Ahhh, I thought that might have been the problem. I need some kind of compiler then I take it. Can you name any programs to help? Thanks /bow.gif' class='bbc_emoticon' alt='(bow)' />

A Quick log in to Invision based forums for your site.

Code: Select all

<form style="display:inline" action="http://forums.killagraphix.com/index.php?act=Login&CODE=01&CookieDate=1" method="post">

</form>

If you wish to use this code on your site, for your forums be sure to replace forums.killagraphix.com with your boards url for eg. yourdomain.com/forum/

I know this isn't a php script but I thought I'd paste it here any how.

Seeing how a lot of you use phpbb forums I thought I'd post this:

Let's take a look at the phpBB table phpBB_users; you'll see a list
of fields. The fields we need are:
-> username
-> user_posts
What we are going to do is:
-> Get username & user's post count from the database
-> Get the next username & user's post count
-> Compare them
-> If the second user's post count is bigger, get put username & post count
into a variable and compare it with the next record.

Code: Select all

<?php 
    $username    = 'username'; 
    $password     = 'password'; 
    $host        = 'localhost'; 
    $connection = mysql_connect ($username, $password, $host);    //Create a MySQL 
connection 

    $query = 'SELECT * from phpbb_users';                 //Create the query 

    $result = mysql_db_query ($db, $query, $connection);        //Run the query on 
the database 

    $user1_posts     = $row['0'];                    //Create 2 empty variables to compare 
    $user1_name        = $row['0'];                //the usernames & post counts 

    while ($row = mysql_fetch_array($result)) {            //Fetch the results from var 
$result 
        $user2_posts     = $row['user_posts'];            //Put the username & post count into 
an temporary variable 
        $user2_name    = $row['username'];            // 
        if ($user2_posts > $user1_posts) {            //Compare the post counts 
            $user1_posts     = $row['user_posts'];        //If the new one is bigger, replace 
the old one with the new one 
            $user1_name    = $row['username']; 
        } 
    } 

    print ('Top poster: ' . $user1_name . ' with ' . $user1_posts . '.'); 
?>

That's it!

Browser Redirect:

Alright, this is a simple little script which will take you to one page if you're using Internet Explorer, and another page if you're using some other browser. Lets decide what this is going to do in English:

If the browser is MicroSoft Internet Explorer (MSIE), then go to spoono.com
If the browser isn't MSIE, then redirect to yahoo.com.

The most essential part of this is that this code has to be sent out before any output to the HTML page. Make sure it is the first line of code on your PHP page. With that said, here is the PHP:

<?
//if its MSIE then
if ($name = strstr ($HTTP_USER_AGENT, "MSIE"))
{
//go to Spoono
Header ("Location: [url="http://www.spoono.com/");"]http://www.spoono.com/");[/url]
}
else
{
//else go to Yahoo
Header ("Location: [url="http://www.yahoo.com/");"]http://www.yahoo.com/");[/url]
}
?>

 $_UA=strtolower($GLOBALS['HTTP_USER_AGENT']);
 
 // Try to detect Primary language if several languages are accepted.
 foreach($GLOBALS['_LANG'] as $K)

   return $K;
 }
 
 // Try to detect any language if not yet detected.

   return $K;
 }
 foreach($GLOBALS['_LANG'] as $K)
 {
  if(preg_match("/[\[\( ]{$K}[;,_\-\)]/",$_UA))

 }
 
 // Return default language if language is not yet detected.
 return $GLOBALS['_DLANG'];
}

// Define default language.
