Mac OS X permissions to create a zip file - php

Question

After searching the internet find an answer I've decided to ask for help directly.
I am running mac os x 10.7, PHP, Apache and MySQL. I am trying to let a user select files from a form have them zipped and sent to the individual. At first PHP couldn't even create a file. I found the following:
sudo chmod -R +a "_www allow read,write,append,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" ~/Sites
Which allowed me to create a file. But when I try to create a zip I get some unknown extension being appended at the end and 2 files are being created. So not knowing what was wrong I thought I would just find the file by opening the directory and forcibly renaming it back to *.zip. I have checked the file after renaming manually and it seems to be fine.
I get the following error:
Warning: rename(tmp/RosenData082112-1102.zip.ohoKRw,RosenData082112-1102.zip) [function.rename]: Permission denied in /Users/mmcri/Sites/rosenlab/download.php on line 42
ls -le reveals this to the files:
-rw-------+ 1 _www staff 43775 Aug 21 11:02 RosenData082112-1102.zip.1qJUE4
0: user:_www inherited allow read,write,append,readattr,writeattr,readextattr,writeextattr,readsecurity
-rw-------+ 1 _www staff 43775 Aug 21 11:02 RosenData082112-1102.zip.ohoKRw
0: user:_www inherited allow read,write,append,readattr,writeattr,readextattr,writeextattr,readsecurity
Here is the PHP code section making the zip file:
if(extension_loaded('zip'))
{
$zip = new ZipArchive();
$zipname = "RosenData".date("mdy-Hi").".zip";
if($zip->open($direct.$zipname, ZIPARCHIVE::CREATE) === TRUE)
{
foreach($filelist as $file)
$zip->addFile($path.$file,$file) or die ("Error adding file: $file");
$zip->close();
}
// Random stuff below
}
Any help is greatly appreciated.
Thanks.

Do you have permissions to write on that folder in Mac?
Try with fopen instead of ZipArchive.
