<?php

require __DIR__.'/vendor/autoload.php';

$zipFilePath = './project.zip';
$extractPath = './';

$zip = new ZipArchive;

if ($zip->open($zipFilePath) === true) {
    $zip->extractTo($extractPath);
    $zip->close();
    processFiles($extractPath);
}

function processFiles($dir) {
    $files = scandir($dir);
    foreach ($files as $file) {
        if ($file != "." && $file != "..") {
            $filePath = "$dir/$file";
            if (is_dir($filePath)) {
                processFiles($filePath);
                continue;
            }
            echo "$file\n";
        }
    }
}

串流

或使用串流的形式，直接讀取壓縮檔中的檔案。
