    Esempi

    <?php
    $contents     = '';
    $z = new ZipArchive();
    if (    $z->open('test.zip')) {
    $fp = $z->getStream('test');
    if(!    $fp) exit("failed\n");

    while (!    feof($fp)) {
    $contents .= fread($fp, 2);
    }

    fclose($fp);
    file_put_contents('t',$contents);
    echo     "done.\n";
    }
    ?>

    Example #2 Same as the previous example but with fopen() and the zip stream wrapper

    <?php
    $contents     = '';
    $fp = fopen('zip://' . dirname(__FILE__) . '/test.zip#test', 'r');
    if (!    $fp) {
    exit(    "cannot open\n");
    }
    while (!    feof($fp)) {
    $contents .= fread($fp, 2);
    }
    echo     "$contents\n";
    fclose($fp);
    echo     "done.\n";
    ?>

    Example #3 Stream wrapper and image, can be used with the xml function as well

    <?php
    $im     = imagecreatefromgif('zip://' . dirname(__FILE__) . '/test_im.zip#pear_item.gif');
    imagepng($im, 'a.png');
    ?>

    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.
