PHP将多级目录打包成zip文件

$zip = new ZipArchive();
//参数1:zip保存路径，参数2：ZIPARCHIVE::CREATE没有即是创建
if(!$zip->open("$exportPath.zip",ZIPARCHIVE::CREATE))
{
    echo "创建[$exportPath.zip]失败<br/>";return;
}
//echo "创建[$exportPath.zip]成功<br/>";
$this->createZip(opendir($exportPath),$zip,$exportPath);
$zip->close();

 

/*压缩多级目录
        $openFile:目录句柄
        $zipObj:Zip对象
        $sourceAbso:源文件夹路径
    */
function createZip($openFile,$zipObj,$sourceAbso,$newRelat = '')
{
    while(($file = readdir($openFile)) != false)
    {
        if($file=="." || $file=="..")
            continue;

        /*源目录路径(绝对路径)*/
        $sourceTemp = $sourceAbso.'/'.$file;
        /*目标目录路径(相对路径)*/
        $newTemp = $newRelat==''?$file:$newRelat.'/'.$file;
        if(is_dir($sourceTemp))
        {
            //echo '创建'.$newTemp.'文件夹<br/>';
            $zipObj->addEmptyDir($newTemp);/*这里注意：php只需传递一个文件夹名称路径即可*/
            $this->createZip(opendir($sourceTemp),$zipObj,$sourceTemp,$newTemp);

        if(is_file($sourceTemp))
