File Zipping using RecursiveIteratorIterator?

[random1]

Hi All,

 

I have the following code for zipping up a folder:

 

	ini_set('max_execution_time', 50000); // 50 seconds

	// create object
	$zip = new ZipArchive();

	// open archive 
	if ($zip->open($destinationpath, ZIPARCHIVE::CREATE) !== TRUE)
	{
		return 'Could not open archive ' . $destinationpath;
	}

	// initialize an iterator
	// pass it the directory to be processed
	$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($folders));

	// iterate over the directory
	// add each file found to the archive
	foreach ($iterator as $key=>$value)
	{
		$zip->addFile(realpath($key), $key) or die ('ERROR: Could not add file: ' . $key);
	}

 

This code works fine for some directories but others trigger:

 

die ('ERROR: Could not add file: ' . $key);

 

I think the issue has to do with:

 

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($folders));

 

Is this way to do this? Is there an alternative?

Check your permissions on the folders before doing anything... there is no reason i can think of besides you have the wrong permissions for it to work on one folder but not another.

Hmm... I found this:

Currently the number of files that can be added using addFile to the ZIP archive (until it is closed) is limited by file descriptors limit.

 

How can I take this into account in the code?
