How to extract zip archive with file rename if there are duplicates in the destination folder (PHP)

This is an example of a function that extracts files from an archive, renaming them if there are files with the same name in the destination folder:

function extractZip($zipFilePath, $folderToExtract) 

{

        $zipArchive = new ZipArchive();

        $result = $zipArchive->open($zipFilePath);

        if ($result === TRUE) { 

            for ($i = 0; $i < $zipArchive->numFiles; $i++) {

                $filename = $zipArchive->getNameIndex($i);

				$filePath = $folderToExtract. '/' . $filename;

                if (file_exists($filePath)) {  

                    $fileInfo = pathinfo($filename);

                    $newFileName = $fileInfo['filename'] . '_(copy).' . $fileInfo['extension'];

                    copy("zip://" . $zipFilePath . "#" . $filename, $folderToExtract . '/' . $newFileName);

                } else {

                    copy("zip://" . $zipFilePath. "#" . $filename, $filePath);

                }

            }

            $zipArchive->close();

        } 

 }

Function parameters:

$zipFilePath - path to zip file

$folderToExtract - path to the folder where the archive should be unpacked.

It should be noted that the function has not been tested on nested archives and nested folders.
