| In this tutorial
/ code example we will show you how
to build a simple counter using a MySQL
database . This database will be called
counter , it will contain one table
called counter which will in turn contain
one field called count.
Start MySQL and at the command prompt
type the following
CREATE database counter;
USE counter;
CREATE table counter(count int(10)
DEFAULT '0' NOT NULL);
This creates our MySQL database .
Now for the script to access the count
and display this on our web page.
Replace hostname , username and password
with your own details
<?php
//make a connection
$connection = mysql_connect("hostname","username"
,"password")
or die ("Cannot make that connection");
//connect to our database
$db = mysql_selectdb("counter"
, $connection);
//store the result of the query in
$result
$result = mysql_query("SELECT
* FROM counter");
//retrieve the fields in our table
$fields = mysql_fetch_row($result);
//update the count field by 1
mysql_query("UPDATE counter SET
count = count+1");
//$mycount variable is set to the
first field (count)
$mycount = $fields[0];
//display the count
echo $mycount;
?>
