PPH Text Editing Errors

programming

Hi guys. I’m currently studying PHP language. I already installed IIS on my PC and a PHP server, and test some codes that i found from a tutorial. But there was an error. I can’t determine what was the problem.

This was the code from the tutorial.

<?php
    $today = date("y-m-d");
    $fh = fopen("flat.txt","a");
    fwrite($fh,$today);
    fclose($fh);
    echo "$today";
?>

This was the output from my PC.

07-08-07PHP Warning: fopen(flat.txt) [function.fopen]: failed to open stream:
Permission denied in C:\Inetpub\wwwroot\simple_editor\flat.php on line 3 PHP Warning:
fwrite(): supplied argument is not a valid stream resource in
C:\Inetpub\wwwroot\simple_editor\flat.php on line 4 PHP Warning: fclose(): supplied
argument is not a valid stream resource in C:\Inetpub\wwwroot\simple_editor\flat.php on
line 5

I think there are no problems from the code itself. I think the problem came from my computers security. Can any one help me out.

Thanks in advance.
