In this small example we are going to build a simple web counter.
First of all we read a text file in which we store our counter value. Depending on that value we display the counter value using images. Then we increase the counter value by 1 and write back to the text file.
Really simple script for beginners.... Will work well on low traffic sites where there is little chance for diffrent users to overite each others updates.
| <?php
$fp = fopen ("counter.txt", "r");
$count_number = fread ($fp, filesize ("counter.txt"));
fclose($fp);
?>
<html>
<head>
<title>Counter number</title>
</head>
<body>
<center>
<?php
$counter = (int)($count_number) + 1;
$count_number = (string)($counter);
$len = strlen($count_number);
while($len!=$i && $len!=0)
{
echo "<img src=". $count_number[$i].".jpg alt=\"visitor number $count_number\" width=20 Height=22>";
$i++;
}
$fp = fopen ("counter.txt", "w");
fwrite ($fp, $count_number);
fclose($fp);
?>
</center>
</body>
