I'm having trouble with this COUNTER.

[cosmo7]

Hello
I have this counter "system" that's built from a php script and a txt file (set to 0) placed in the same directory.
The script is as follows:

<?php
     // path to counter.txt
    $counter_file = "./counter.txt";
    // Open the file for reading
    if (!($fp = fopen($counter_file, "r"))) die ("Cannot Open $counter_file.");
    // Read 20 characters from the file
    $counter = (int) fread($fp, 20);
    // Close the file
    fclose($fp);
    // Increment the counter
    $counter++;
    // Display the counter
    echo "You are visitor Number $counter.";
    // Open the file, in write mode
    $fp = fopen($counter_file, "w");
    // Write the new value of counter to the file.
    fwrite($fp, $counter);
    // Close the text file.
    fclose($fp);
?>

It reads from the file OK and outputs the digits
For example it writes: You are visitor number 1
The problem is when it tries to open the file in write mode
It outputs the following lines:
Warning: fopen("./counter.txt","w") - Permission denied in /usr/www/users/kisufim/counter/index.php3 on line 16

Warning: Unable to find file identifier 0 in /usr/www/users/kisufim/counter/index.php3 on line 18

Warning: Unable to find file identifier 0 in /usr/www/users/kisufim/counter/index.php3 on line 20

Permission Denied => You didnt assign proper permission for counter.txt file and the directory its in

If u r using FTP add write permissions to counter.txt

assign 0777 if its four digit. or 777 if three digit

if u have terminal access.. you can use following command

chmod 777 ./counter.txt

Good Luck
