# ZipArchive 类版本要求，来自官网
# (PHP 5 >= 5.2.0, PHP 7, PHP 8, PECL zip >= 1.1.0)

#查看是否安装zlib包
yum list installed | grep zlib


php-fpm -m | grep zip
zip

$zipVersion = phpversion('zip');
echo "Zip Extension Version: " . $zipVersion.PHP_EOL;

# 输出结果 
# Zip Extension Version: 1.15.6

//压缩包生成的路径,最后文件添加在这个zip包中
$destination = '/home/wwwroot/testDemo.zip';

$fileSuffix = pathinfo($filePath,PATHINFO_EXTENSION); // 输出 pdf
$fileName = pathinfo($filePath, PATHINFO_FILENAME);   // 输出 劳务派遣协议
$rename = 'stark_' . $fileName.'.'.$fileSuffix; //新名字

#把路径$filePath 生成到zip包中,$rename是新的文件名
$zip->addFile($filePath,  $rename );

# 创建目录的路径
$createPathName = '';
$zip->addEmptyDir($createPathName);
$zip->close();
