Need PHP script to decompress and loop through zipped file

Question

I am using a fairly straight-forward script to open and parse several xml files that are gzipped. I also need to do the same basic operation with a ZIP file. It seems like

There is a smart way to do it with ZipArchive. You can use a for loop with ZipArchive::statIndex() to get all the information you need. You can access the files by their index (ZipArchive::getFromIndex()) or name (ZipArchive::getFromName()).

For example:

function processZip(string $zipFile): bool
{
    $zip = new ZipArchive();
    if ($zip->open($zipFile) !== true) {
        echo '<p>Can\'t open zip archive!</p>';
        return false;
    }

    // As long as statIndex() does not return false keep iterating
    for ($idx = 0; $zipFile = $zip->statIndex($idx); $idx++) {
        $directory = \dirname($zipFile['name']);

        if (!\is_dir($zipFile['name'])) {
            // file contents
            $contents = $zip->getFromIndex($idx);
        }
    }
    $zip->close();
}

If you have PHP 5 >= 5.2.0, PECL zip >= 1.5.0 then you may use the ZipArchive libraries:

$zip = new ZipArchive; 
if ($zip->open('source.zip') === TRUE) 
{ 
     for($i = 0; $i < $zip->numFiles; $i++) 
     {   
        $fp = $zip->getStream($zip->getNameIndex($i));
        if(!$fp) exit("failed\n");
        while (!feof($fp)) {
            $contents = fread($fp, 8192);
            // do some stuff
        }
        fclose($fp);
     }
} 
else 
{ 
     echo 'Error reading zip-archive!'; 
}
