Help with zipping files

Hi,

I have come across a requirement in which I need to zip files. This is fine but the requriement has one conditions like below:

One .z file can not have more than 10,000 files

Now in the directory I have several files liek below:

aaa_file_10_00001.txt
aaa_file_10_00002.txt
aaa_file_20_00001.txt
aaa_file_30_00001.txt
aaa_file_10_00003.txt
...........................
...........................
...........................
aaa_file_30_00750.txt
aaa_file_30_10005.txt

If i have to zip the above files, I will have 4 .z files. One for files like aaa_file_20_*.txt, one for files like aaa_file_30_*.txt and two for files like aaa_file_10_*.txt I am planning to move files of different type (diferentiated by 3rd field in the file name) to a temporary directory and zip them. But the problem is I can not zip more than 10,000 files together. How do I move files of type aaa_file_10_*.txt from 1-10000 (this is the value in 4th field of the file name )first, zip them and then move the reamining 10001-10005.

Using a loop is not a good option as per my understanding. Is there any other way of doing it which will not have impact on performance ?

Thanks
Angshuman

ZIPARCHIVE.ADDFILE(3)							 1						     ZIPARCHIVE.ADDFILE(3)

ZipArchive::addFile - Adds a file to a ZIP archive from the given path

SYNOPSIS
bool ZipArchive::addFile NULL (string $filename, [string $localname], [int $start], [int $length]) DESCRIPTION
Adds a file to a ZIP archive from a given path. PARAMETERS
o $filename - The path to the file to add. o $localname - If supplied, this is the local name inside the ZIP archive that will override the $filename. o $start - This parameter is not used but is required to extend ZipArchive. o $length - This parameter is not used but is required to extend ZipArchive. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
This example opens a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt. Example #1 Open and add <?php $zip = new ZipArchive; if ($zip->open('test.zip') === TRUE) { $zip->addFile('/path/to/index.txt', 'newname.txt'); $zip->close(); echo 'ok'; } else { echo 'failed'; } ?> NOTES
Note When a file is set to be added to the archive, PHP will lock the file. The lock is only released once the ZipArchive object has been closed, either via ZipArchive::close or the ZipArchive object being destroyed. This may prevent you from being able to delete the file being added until after the lock has been released. PHP Documentation Group ZIPARCHIVE.ADDFILE(3)
