PHPZipArchive函数每次都会询问路径

我正在使用以下脚本创建一个zip文件。一切工作正常，但是问题是当我运行脚本时，它会打开对话框进行保存，并询问我的位置及其对客户的刺激。你们能告诉我如何自动保存在$ zip_file中提到的路径上而不问什么吗？

$dir = 'c:/dev/';
$zip_file = 'e:/file.zip';
// Get real path for our folder
$rootPath = realpath($dir);
// Initialize archive object
$zip = new ZipArchive();
$zip->open($zip_file,ZipArchive::CREATE | ZipArchive::OVERWRITE);
// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($rootPath),RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $name => $file)
{
// Skip directories (they would be added automatically)
if (!$file->isDir())
{
// Get real and relative path for current file
$filePath = $file->getRealPath();
$relativePath = substr($filePath,strlen($rootPath) + 1);
// Add current file to archive
$zip->addFile($filePath,$relativePath);
}
}
// Zip archive will be created only after closing object
$zip->close();

readfile($zip_file);
