PHP readdir and opendir don't work?

Posts: 9 · Posted: Sun Apr 13, 2008 6:21 am

So I'm trying to use the following code snippet from the PHP.net website...

Code:

<?php
// Note that !== did not exist until 4.0.0-RC2

if ($handle = opendir('/calculator')) {
echo "Directory handle: $handle\n";
echo "Files:\n";

/* This is the correct way to loop over the directory. */
while (false !== ($file = readdir($handle))) {
echo "$file\n";
}

closedir($handle);
}
?>

...and I keep getting the following error message...

Warning: opendir() [function.opendir]: SAFE MODE Restriction in effect. The script whose uid is 72582 is not allowed to access / owned by uid 0 in /vservers/mywebsite/htdocs/programming/index.php on line 37

Warning: opendir(/calculator) [function.opendir]: failed to open dir: No such file or directory in /vservers/mywebsite/htdocs/programming/index.php on line 37

I'm still a bit new to PHP so can someone tell me what's going wrong?

Oh, and I'm on a shared server. I guess this is a permissions issue, but Dreamweaver doesn't seem to be letting me change permissions on the directory.

Thanks Smile

Nevermind, I figured it out. In the line:

opendir('/calculator')

you can't have the "/" in front of calculator. It works fine if you use:

opendir('calculator')

or even

opendir('.')

if you want it to read the current directory.

I still don't know why Dreamweaver isn't letting me change permissions, however.
