[FX.php List] Upload script in PHP?

[Dale Bengston]

Argh, I was dodging the permissions part. Now you're going to make me  
think!

You've probably discovered that just making a folder in /Library/ 
WebServer/Documents on your web server sets the ownership to your  
current OSX login. Since the www user (Linux: nobody) has a pretty  
small sandbox to play in, it can't move a file to this folder.

Here's a trick I borrowed from Marisa Smith: Set the permissions for  
your upload folder to something loose before the upload
<?php
  chmod($pathToFolder,0666);
?>

and then set them back to something tighter afterward
<?php
chmod($pathToFolder,0222)].
?>

You can read about doing permissions with PHP at <http://us2.php.net/ 
manual/en/function.chmod.php>.
