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

This tutorial demonstrates how to efficiently process XML documents using PHP. XML (eXtensible Markup Language) is a versatile text-based markup language designed for both human readability and machine parsing. It's commonly used for data storage an

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
