php打包压缩文件之ZipArchive方法用法分析_PHP
本文实例讲述了php打包压缩文件之ZipArchive方法用法。分享给大家供大家参考,具体如下:
前面说到了php打包压缩文件之PclZip方法,今天来说下另一种更为简单的方法,使用ZipArchive来压缩文件。这个是php的扩展类,自php5.2版本以后就已经支持这个扩展,如果你在使用的时候出现错误,查看下php.ini里面的extension=php_zip.dll前面的分号有没有去掉,然后再重启Apache这样才能使用这个类库。
使用ZipArchive压缩文件是非常简单的,php官网已经给我提供了很多相关示例,大家可以看下 http://www.php.net/manual/zh/class.ziparchive.php,例如:
<?php $zip = new ZipArchive; //首先实例化这个类 if ($zip->open('test.zip') === TRUE) { //然后查看是否存在test.zip这个压缩包 $zip->addFile('too.php'); $zip->addFile('test.php'); //将too.php和test.php两个文件添加到test.zip压缩包中 $zip->close(); //关闭 echo 'ok'; } else { echo 'failed'; } ?>
下面是一些参数说明:
<?php /******** ziparchive 可选参数 *******/ /* 1.ZipArchive::addEmptyDir 添加一个新的文件目录 2.ZipArchive::addFile 将文件添加到指定zip压缩包中。 3.ZipArchive::addFromString 添加的文件同时将内容添加进去 4.ZipArchive::close 关闭ziparchive 5.ZipArchive::extractTo 将压缩包解压 6.ZipArchive::open 打开一个zip压缩包 7.ZipArchive::getStatusString 返回压缩时的状态内容,包括错误信息,压缩信息等等 8.ZipArchive::deleteIndex 删除压缩包中的某一个文件,如:deleteIndex(0)删除第一个文件 9.ZipArchive::deleteName 删除压缩包中的某一个文件名称,同时也将文件删除。 ...... */ ?>
总之只要你的php5.2版本以上,使用ZipArchive来进行文件压缩还是比较方便的。具体的和PclZip哪一个运行速度比较快,这个磊子还没有做过测试,大家感兴趣的可以折腾折腾。

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,
