i have this code which is supposed to increment a counter on page
it is reading from text file and display the value from file but it is failing to update the file with the new value which is an increment of the counter
<?php
//create a file called counter.txt and upload it to your server
//now open the file
$fp = fopen("counter.txt" , "r");
//read in the current count
$count = (int)fread($fp, 1024);
//increment the count by 1
$count++;
//close the file
fclose($fp);
//image display, get the lentgth of the count
echo"<table cellspacing=0 width =4% cellpadding=0 row=1 column=".strlen($count);
echo"<tr>";
for ($i = 0 ;$i < strlen($count) ; $i++)
{
$imgsrc = substr($count,$i ,1);
//display the image(s) note our images are in a folder located at
//images/count1/ change this to your location
echo"<td width=2%>";
echo "<img src =\"images/count1/" . $imgsrc . ".gif\">";
echo"</td>";
}
echo"</tr>";
echo"</table>";
//open the counter file
$fp = fopen("counter.txt", "w");
//write the new count to the file
fwrite($fp, $count);
//close the file
fclose($fp);
//include("grcounter.php");
?>

try this:
<?php
$open = fopen('counter.txt', 'r');
$read = fread($open, filesize('counter.txt'));
fclose($open);
$count = $read + 1;
$open = fopen('counter.txt', 'w');
$write = fwrite($open, $count);
fclose($open);
echo"<table cellspacing=0 width =4% cellpadding=0 row=1 column=".strlen($count);
echo"<tr>";
for ($i = 0 ;$i < strlen($count) ; $i++)
{
$imgsrc = substr($read,$i ,1);
//display the image(s) note our images are in a folder located at
//images/count1/ change this to your location
echo"<td width=2%>";
echo "<img src =\"images/count1/" . $imgsrc . ".gif\">";
echo"</td>";
}
echo"</tr>";
echo"</table>";
?>
<?php
$open = fopen('counter.txt', 'r');
$read = fread($open, filesize('counter.txt'));
fclose($open);
$count = $read + 1;
$open = fopen('counter.txt', 'w');
$write = fwrite($open, $count);
fclose($open);
echo"<table cellspacing=0 width =4% cellpadding=0 row=1 column=".strlen($count);
