php不同版本使用zip扩展创建压缩文件
最近使用zip扩展进行文件压缩，结果发现在php5.5及以下版本使用zip扩展正常，但是切换到php5.6 php7就无法使用压缩功能，压缩文件注意要点：
1.PHP7删除了ereg方法，导致ZipArchive无法使用
2.路径不支持中文名
3.压缩后压缩文件还有多级目录的问题
4.需要php.ini中 zlib.output_compression = On 如果是php5.6以下要启用extension=php_zip.dll，php7已经集成zip扩展
下面代码解决了上述问题，而且在php各版本测试都能正常使用

使用方法 Controller中
public function actionBatchall(){ try{ $ids=Yii::$app->request->post('ids'); $ids=explode(',',$ids); $lists = PatentData::find()->where(['in','id',$ids])->select(['patent_id','title','content'])->all(); if($lists){ $now=date('YmdHis'); $dir='./download/'.$now; if(!Zip::check_dir($dir)){ die('{"status":"1","error":"'.$dir.':目录生成失败！！"}'); } foreach($lists as $list){ $filename = $list['title']; $patent_id=$list['patent_id']; if(!$aburl=Zip::match_pdf($list['content'])){ die('{"status":"1","error":"'.$patent_id.$filename.':匹配pdf失败！！"}'); } if(!is_file($aburl)){ die('{"status":"1","error":"'.$patent_id.$filename.':文件不存在！！"}'); } $file = file_get_contents($aburl); if(strtoupper(substr(PHP_OS,0,3))==='WIN'){
//保证可以使用中文名 $link = iconv('utf-8', 'gb2312', $dir.'/'.$patent_id.$filename.'.pdf'); //$link = iconv('utf-8', 'gb2312', $dir.'/'.$patent_id.'.pdf'); }else{ $link = $url; } file_put_contents($link,$file); } // 压缩文件夹 php 5.5以下可用 // $zip = new \ZipArchive(); // if ($zip->open($dir.'.zip', \ZipArchive::OVERWRITE) === TRUE) { // Zip::addFileToZip($now.'/', $zip); //调用方法，对要打包的根目录进行操作，并将ZipArchive的对象传递给方法 // $zip->close(); // } // /********************php7及以下版本都可用*******************/ $z = new PhpZip(); //新建立一个zip的类 $z -> Zip($dir, './download/'.$now.'.zip'); //添加指定目录
if(!is_file('./download/'.$now.'.zip')){ die('{"status":"1","error":"'.$patent_id.$filename.':压缩文件失败！！"}'); } $compress='/download/'.$now.'.zip'; } } catch (\Exception $e) { return Json::encode(['status'=>1,'error'=>$e->getMessage()]); } return Json::encode(['status'=>0,'data'=>$compress]); }
php5.5及以下版本也可以使用，调用方法在上面的注释代码中
