 +====== Making a professional counter in PHP ======
 +
 +**How to make your your own counter, and free!!!**
 +
 +This page explains how to create a professional php counter in your page, or how to use mine to put a counter in your page. Mine is a real free counter that I will keep hosted in this pages as far as I maintain them. 
 +
 +===== How to put the counter in your page =====
 +
 +If your website is called "www.example.com", you will have to cut and paste the following code snippet in your page: 
 +
 +<code html>
 +<a href="http://www.supermanhamuerto.com/stats.php?site=example.com&page=main" target="_blank">
 +<img src="http://www.supermanhamuerto.com/cont2.php?site=example.com&page=main">
 +</a>
 +</code>
 +
 +
 +Suppose you want to have many counters in your page; let's say that one is for a public site, other is for the mailing lists, other is for whatever: you can use the 'page' parameter to personalize the counters you want to have. 
 +
 +If you are only interested in the use of the counter, you are done. If you want to make your own counter, please keep reading. 
 +
 +===== Things you must have =====
 +
 +In order that the following code works properly, you have the following in your website: 
 +
 +  * a running mysql database (I won't consume much resources of it, but I need a space to keep track of the sessions and the counter values)
 +  * permission to run php in your web site (later we will go over this)
 +  * the "gd" graphics libary installed in your system
 +
 +==== Setting up the database ====
 +
 +It is desirable to have a mysql database with a user with select, update, delete and insert permission over two tables. Here is the code you have to execute as root in order to create things properly: 
 +
 +<code sql>
 +
 +create database freecounter; // or the name you want to give to this 
 +
 +use freecounter;
 +
 +create table if not exists session
 + (site        varchar(250),
 +  page        tinytext,
 +  sessionid   varchar(50),
 +  creation    datetime, 
 +  last        datetime,
 +  useragent   tinytext, 
 +  ip          varchar(50),
 +  pages       int(16));
 +
 +create table if not exists counter
 +(site    varchar(250),
 + page    tinytext, 
 +  count   int(16));
 +  
 +grant select, insert, delete, update 
 +  on freecounter.* to freecounter 
 +  identified by 'CHOOSE A PASSWORD HERE';
 +
 +</code>
 +
 +
 +Check that you have done things well: 
 +
 +<code sql>
 +
 +# mysql -u freecounter -p 
 +password: CHOOSE A PASSWORD HERE
 +
 +mysql> use freecounter; 
 +
 +mysql> select * from session; 
 +
 +mysql> select * from counter; 
 +
 +</code>
 +
 +==== Test that php is running in your site ====
 +
 +Create a file "hello.php" with the following: 
 +
 +<code php>
 +<?php
 +
 +echo( "hello world" ); 
 +
 +?>
 +</code>
 +
 +And check that you see it correctly in a web browser. Let's say that your website is "www.example.com". So, to see this page you should type in a web browser the following: ''http://www.example.com/hello.php''. And you should see the message "hello world". If not, check things.
 +
 +
 +==== Check that GD library is installed and working ====
 +
 +Edit again the "hello.php" and change by the following: 
 +
 +<code php>
 +<?php
 +// Create a 100*30 image
 +$im = imagecreate(100, 30);
 +
 +// White background and blue text
 +$bg = imagecolorallocate($im, 255, 255, 255);
 +$textcolor = imagecolorallocate($im, 0, 0, 255);
 +
 +// Write the string at the top left
 +imagestring($im, 5, 0, 0, 'Hello world!', $textcolor);
 +
 +// Output the image
 +header('Content-type: image/png');
 +
 +imagepng($im);
 +imagedestroy($im);
 +?>
 +
 +
 +</code>
 +
 +And press the "refresh" button of your browser or open a new one. You should see again the message "Hello world", but this time is a picture showing this message instead of a message (if you don't understand what I'm saying, probably you shouldn't have to continue reading some points ago). 
 +
 +==== And finally the code ====
 +
 +
 +And finally, the code. You have to create two pages, ''cont2.php'' and ''stats.php''. Yes, I could have an include page to put the functions, but I do not want to have all the things properly one: an opportunity to you to enhace things a bit. However, there are the source code: 
 +

 +==== Finally, wrap it alltogether ====
 +
 +
 +You can make a simple html page to see how it looks like: 
 +
 +<code html>
 +<html>

 +<body bgcolor="silver">
 +
 +<a href="http://www.supermanhamuerto.com/stats.php?site=example.com&page=main" target="_blank">
 +<img src="http://www.supermanhamuerto.com/cont2.php?site=example.com&page=main">
 +</a>
 +
 +</body>
