PHP实例代码分析:将文件夹压缩成ZIP
php中生成zip其实很简单,只要下面2步就能完成。
1.请先下载我准备好的zip.php工具类,下载后解压,将里面的文件放入对应的目录中,我是放在虚拟目录下的include文件夹中。
2.在你的php文件中加入下面代码即可
require_once "./include/zip.php";
$zip = new PHPZip();
//$zip -> createZip("要压缩的文件夹目录地址", "压缩后的文件名.zip"); //只生成不自动下载
$zip -> downloadZip("要压缩的文件夹目录地址", "压缩后的文件名.zip"); //自动下载
实例:可以参考下面的伪代码来看一个具体的使用场景:
if (!$download) {
exit();
}
set_time_limit(60);
$tmpManager = new TmpManager(); //假设我们有一个类来完成后面的操作
$tempfolder = array();
$tempfile = array();
//假设我们是通过在页面上选择checkbox来下载已选的文件夹或文件,并一同打包
for($i = 0;$i $value = ${"select".$i};
if ($value != '') {
$this_type = substr($value, 0, 1);
$this_id = substr($value, 1);
//将文件夹和文件的情况分开处理
if ($this_type == 'd') {
$tempfolder[] = $this_id;
}
elseif ($this_type == 'f') {
$tempfile[] = $this_id;
}
}
}
@mkdir($tempdir);
$curtempdir = "$tempdir/".$userid; //不同用户在不同的临时文件夹下操作
if (file_exists($curtempdir)) {
$tmpManager->DeleteDir($curtempdir); //删除旧的文件夹
}
if (sizeof($tempfolder) > 0 || sizeof($tempfile) > 0) {
mkdir($curtempdir, 0777); //如果有要打包的文件货文件夹,重新创建文件夹
}
if (sizeof($tempfile) > 0) {
$tmpManager->CopyFile($tempfile,$curtempdir); //将要下载的文件copy到创建的文件夹
}
if (sizeof($tempfolder) > 0) {
$tmpManager->CopyFolder($tempfolder,$curtempdir); //将要下载的文件夹copy到创建的文件夹
}
$zip = new PHPZip();
$zip -> downloadZip($curtempdir, "file_".date('Ymd').".zip"); //打包并下载
