On Win 2K localhost: "failed to open stream"

New Member Joined: Oct 26, 2004 Posts: 5

Hello,

I am new to this... and find PHP much easier to use on my remote server than on my local PC. (But that's a slow way to learn!)

Basic "hello world" and "phpinfo" scripts work fine locally, and phpinfo reports PHP 5 installed with lots o' goodies. I seem to stumble trying to open and/or read and/or modify files with PHP scripts.

This short script works fine on my server (and "counter.dat" exists, FYI, both locally and on server):

<?php
$counter_file = "count.dat";
if(!($fp = fopen($counter_file, "r"))){
die ("Cannot open $counter_file.");
}
$counter = (int) fread($fp, 20);
fclose($fp);

$counter++;

echo "You're visitor No. $counter.";

$fp = fopen($counter_file, "w");
fwrite($fp, $counter);
fclose($fp);
?>

Does not work on my Win 2K local PC, however, with IIS running. Tried both with "counter.dat" and "C:\\Inetpub\\wwwroot\\etc..." as path to file. (Counter.dat is in same folder as script.)

Going from
ADMINISTRATIVE TOOLS |
INTERNET SERVICES MANAGER |
DEFAULT WEB SITE
to the specific folder, I have checked the Properties tab so that read, write, script source access selected for this subdirectory, and Execute Permissions set to "Scripts Only." No joy.

I am sure I am missing something somewhere.

All guidance welcome!

Thanks

You are probably also receiving a Permission Denied error message, correct? Please post the entire error message. It will tell you the line that the error is occurring on.

I was thinking he should use forward slashes in the path but yeah if the relative paths failing too....

Here is the entire error message:

Warning: fopen(c:\Inetpub\wwwroot\DBTest\count.dat) [function.fopen]: failed to open stream: Permission denied in C:\Inetpub\wwwroot\DBTest\dbtest2.php on line 23

Warning: fwrite(): supplied argument is not a valid stream resource in C:\Inetpub\wwwroot\DBTest\dbtest2.php on line 24

Warning: fclose(): supplied argument is not a valid stream resource in C:\Inetpub\wwwroot\DBTest\dbtest2.php on line 25

I read that the double slashes were needed to escape the normal slash... That could just be hooey, or me not understanding the post, but it fails either way.

Your script is not 23 lines long. Can you post the entire script? Double slashes are require with a backward slash but you can use the forward slashes and be done with it.

Here's the whole file:

<?php
$counter_file = "c:\\Inetpub\\wwwroot\\DBTest\\count.dat";
if(!($fp = fopen($counter_file, "r"))){
die ("Cannot open $counter_file.");
}
$counter = (int) fread($fp, 20);
fclose($fp);

$counter++;

echo "You're visitor No. $counter.";

$fp = fopen($counter_file, "w");
fwrite($fp, $counter);
fclose($fp);
?>

Let's verify that the file is being read. Change

Code:

$counter = (int) fread($fp, 20); 


fclose($fp);

to

Code:

$counter = (int) fread($fp, 20); 


die('$counter = '.$counter);


fclose($fp);

Does $counter have a value?

$counter = 0

But is there anything in the file itself, or is PHP defaulting?

When I download and use the counter.dat from the server, and use your new code --

$counter = (int) fread($fp, 20);
die('$counter = '.$counter);
fclose($fp);

-- I get a correct visitor counter number -- it reflects the most recent number from the server. So it reads the file...

My original code correctly increments the counter (so it gives me a counter number one greater than your code above) but is crearly not writing it back to the file.

In that instance, the output stream looks like this:

You're visitor No. 10.
Warning: fopen(c:\Inetpub\wwwroot\DBTest\count.dat) [function.fopen]: failed to open stream: Permission denied in C:\Inetpub\wwwroot\DBTest\dbtest2.php on line 23

Warning: fwrite(): supplied argument is not a valid stream resource in C:\Inetpub\wwwroot\DBTest\dbtest2.php on line 24

Warning: fclose(): supplied argument is not a valid stream resource in C:\Inetpub\wwwroot\DBTest\dbtest2.php on line 25

Same error.... So the counter increments, having read the file I guess, but it does not sucessfully write it. This is the behavior that led me to wonder about permissions....

THANKS

It's a permissions error on your winblows machine. I can't help you with that nor IIS. I would ditch IIS and install Apache.
