Just a little test script to increase the number by 1 every time the page is refreshed and it works fine, but if you hold down F5 to refresh for quite a while, the number decreases and I can't work out why :/

code:

---

<?php

$filename = "count.txt";

$x = file_get_contents("$filename");
file_put_contents("$filename", $x);

$x = $x*1;
$y = $x+1;

$f = fopen($filename, "w");
fwrite($f, $y);
fclose($f);

echo $x;

?>

i dont understand bu the font goes bigger after refreshing once

Wait I am confused with all these mix of varibles, $x and $y, but it should work fine. Maybe it is your browser problem. I try not to use txt files but mysql:

mysql_query("UPDATE views SET views=(views + 1) WHERE id='1");

Wouldn't

code:

---

<?php
    $filename = "count.txt";
    $x = file_get_contents("$filename");
    $x = $x+1;
    file_put_contents("$filename", $x);
    echo $x;
?>

---

code:

---

<?php
    $filename = "count.txt";
    $x = intval(file_get_contents($filename)) + 1;
    $f = fopen($filename, "w");
    fwrite($f,$x);
    fclose($f);
    echo $x;
?>

There are probably loads of easier ways than I used but I wrote this after 4 hours of learning so I still don't know much

I'll try some of these options, thanks

For a counter script, it's also a good idea to use file locking to prevent multiple instances of the script from messing with the file at the same time.

Heres a commented version of a 'hit logger'

code:

---

<?php
// Define the text file to store data
   $HitFile = "logger.txt";
// Open the file for reading and writing
   $handle = fopen($HitFile, "r+");
// Lock the file for exclusive access (protects from data coruption)
   flock($handle, LOCK_EX);
// Get the contents of the file (the old hit count)
   $oldcount = fgets($handle);
// Increment 1 to the old count
   $newcount = $oldcount + 1;
// Set the file head to the begining (destroys the old data)
   rewind($handle);
// Write the new count to the file
   fwrite($handle, $newcount);
// Unlock the file
   flock($handle, LOCK_UN);
// Close the file
   fclose($handle);
// Display the new hit count
echo $newcount;
?>
