第一步:创建MakeZip类文件
<?php class MakeZip{ /** * description:主方法:生成压缩包 * @author: MY * @param $dir_path 想要压缩的目录:如 ‘./demo/‘ * @param $zipName 压缩后的文件名:如 ‘./folder/demo.zip‘ * @return string */ function zip($dir_path, $zipName) { $relationArr = array( $dir_path => array( ‘originName‘ => $dir_path, ‘is_dir‘ => true, ‘children‘ => array() ) ); $key = array_keys($relationArr); $val = array_values($relationArr); $this->modifiyFileName($dir_path, $relationArr[$dir_path][‘children‘]); $zip = new ZipArchive(); //ZIPARCHIVE::CREATE没有即是创建 $zip->open($zipName, ZipArchive::CREATE); $this->zipDir($key[0], ‘‘, $zip, $val[0][‘children‘]); $zip->close(); $this->restoreFileName($key[0], $val[0][‘children‘]); return true; } function zipDir($real_path, $zip_path, &$zip, $relationArr) { $sub_zip_path = empty($zip_path) ? ‘‘ : $zip_path . ‘\‘; if (is_dir($real_path)) { foreach ($relationArr as $k => $v) { if ($v[‘is_dir‘]) { //是文件夹 $zip->addEmptyDir($sub_zip_path . $v[‘originName‘]); $this->zipDir($real_path . ‘\‘ . $k, $sub_zip_path . $v[‘originName‘], $zip, $v[‘children‘]); } else { //不是文件夹 $zip->addFile($real_path . ‘\‘ . $k, $sub_zip_path . $k); $zip->deleteName($sub_zip_path . $v[‘originName‘]); $zip->renameName($sub_zip_path . $k, $sub_zip_path . $v[‘originName‘]); } } } } function modifiyFileName($path, &$relationArr) { if (!is_dir($path) || !is_array($relationArr)) { return false; } if ($dh = opendir($path)) { $count = 0; while (($file = readdir($dh)) !== false) { if(in_array($file,array(‘.‘, ‘..‘, null))) continue; //无效文件,重来 if (is_dir($path . ‘\‘ . $file)) { $newName = md5(rand(0, 99999) . rand(0, 99999) . rand(0, 99999) . microtime() . ‘dir‘ . $count); $relationArr[$newName] = array( ‘originName‘ => iconv(‘GBK‘, ‘UTF-8‘, $file), ‘is_dir‘ => true, ‘children‘ => array() ); rename($path . ‘\‘ . $file, $path . ‘\‘ . $newName); $this->modifiyFileName($path . ‘\‘ . $newName, $relationArr[$newName][‘children‘]); $count++; } else { $extension = strchr($file, ‘.‘); $newName = md5(rand(0, 99999) . rand(0, 99999) . rand(0, 99999) . microtime() . ‘file‘ . $count); $relationArr[$newName . $extension] = array( ‘originName‘ => iconv(‘GBK‘, ‘UTF-8‘, $file), ‘is_dir‘ => false, ‘children‘ => array() ); rename($path . ‘\‘ . $file, $path . ‘\‘ . $newName . $extension); $count++; } } } } function restoreFileName($path, $relationArr) { foreach ($relationArr as $k => $v) { if (!empty($v[‘children‘])) { $this->restoreFileName($path . ‘\‘ . $k, $v[‘children‘]); rename($path . ‘\‘ . $k, iconv(‘UTF-8‘, ‘GBK‘, $path . ‘\‘ . $v[‘originName‘])); } else { rename($path . ‘\‘ . $k, iconv(‘UTF-8‘, ‘GBK‘, $path . ‘\‘ . $v[‘originName‘])); } } } }
第二步:调用index.php文件
<?php /** * 下面代码实现把demo目录压缩成zip包,并以demo.zip为名称存储到folder目录 */ include_once "./MakeZip.class.php"; $makeZip = new MakeZip(); try{ //重复压缩,则会自动覆盖 $res = $makeZip->zip(‘./demo/‘,‘./folder/demo.zip‘); if(!$res){ throw new Exception(‘压缩失败‘); } echo ‘success‘; }catch (Exception $e){ echo $e->getMessage(); }
|--补充
MakeZip类文件中所实例化ZipArchive类 需开启PHP支持ZipArchive
在php.ini文件中将extension=php_zip.dll 开头的;的去掉。
