Here a way to handle specific files from a zip archive without full extract :

<?php

$zip_file = '/path/to/file.zip'; // I wan to get stream a CSV files

$zip = new ZipArchive();
$zip->open($zip_file);
for ($i = 0; $i < $zip->numFiles; $i++) { // Check file by file
    $name = $zip->getNameIndex($i); // Retrieve entry name
    $extension = pathinfo($name, PATHINFO_EXTENSION);
    if ($extension === 'csv') { // I want to handle csv files
        $stream = $zip->getStream($name); // No stream index access before PHP 8.2
        // Starting PHP 8.2 $zip->getStreamIndex() or $zip->getStreamName()
        // Do stuff with $stream
        // ...
    }
}

Keep in mind that this stream is not rewindable/seekable.
