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.
