PHP将特定目录排除在Zip中

Question

I have a particular directory called 'customers' that contains various directories. One of the directories is called uploads. Basically where users update their content. This folder contains hundreds of pictures.

What I want is that all the files in this particular directory is added to a zip file except the 'uploads' directory which is backed up separately.

This is the code I am trying to use:

$zipFolderExclude = 'customers/uploads/*.*';

// create object
$zip = new ZipArchive();
// open archive
if ($zip->open($zipName, ZIPARCHIVE::CREATE) !== TRUE) {
    die ("Could not open archive");
}
// initialize an iterator
// pass it the directory to be processed
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($zipFolder));
// iterate over the directory
// add each file found to the archive
foreach ($iterator as $key=>$value) {
    if(!is_dir($zipFolderExclude) ) {
        $zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
        echo $key . '<br/>';
    }
}
// close and save archive
$zip->close();
echo "Archive created successfully.";

The above code is zipping all files. I'm not sure what to do in this particular code:

if(!is_dir($zipFolderExclude) ) {
            $zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
            echo $key . '<br/>';
        }

How can I exclude the uploads directory from the zip, please?

Since ZipArchive does not explicitly support exclusions (of some directories), you may apply two strategies:

• Strategy 1: use ZipArchive::addGlob ( http://www.php.net/manual/en/ziparchive.addglob.php ) to filter in only desired directories. Optionally use ZipArchive::addPattern(pattern) for fine tuning included filenames within the directory.
• Strategy 2: include all directories into ZipArchive and then delete unwanted directory with ZipArchive::deleteIndex(index) - see http://www.php.net/manual/en/ziparchive.deleteindex.php . Simple, but may eat up memory depending on the size of unwanted directories.
