First experience with php yield, recursively traverse folders and compress them

private function zip($path,$zipFile){ $zip=new ZipArchive(); $zip->open($zipFile,ZipArchive::CREATE);//创建一个空的zip文件 $this->addFileToZip($path,$zip); } private function addFileToZip($path,ZipArchive $zip,$root=''){ if(!is_dir($path)){ return false; } if(!$root){ $root= $path; } if(strpos($path,$root)!==0){ $root= $path; } $handler=opendir($path); //打开当前文件夹由$path指定。 while(($filename=readdir($handler))!==false){ if($filename != "." && $filename != ".."){//文件夹文件名字为'.'和‘..’，不要对他们进行操作 if(is_dir($path."/".$filename)){// 如果读取的某个对象是文件夹，则递归 $this->addFileToZip($path."/".$filename, $zip,$root); }else{ //将文件加入zip对象 $filenameWithPath = $path."/".$filename; $localFileName = substr($filenameWithPath,strlen($root)); $zip->addFile($filenameWithPath,$localFileName); } } } @closedir($handler); }

private function zipFolder($folder,$zipFile){ $zip=new ZipArchive(); $zip->open($zipFile,ZipArchive::CREATE);//创建一个空的zip文件 foreach($this->yieldFile($folder) as $file){ $localFileName = substr($file,strlen($folder)); $zip->addFile($file,$localFileName); } } private function yieldFile($path){ if(is_dir($path)){ $handler = opendir($path); while(($filename=readdir($handler))!==false){ if($filename != "." && $filename != "..") {//文件夹文件名字为'.'和‘..’，不要对他们进行操作 if(is_dir($path."/".$filename)){// 如果读取的某个对象是文件夹，则递归 foreach($this->yieldFile($path."/".$filename) as $file){ yield $file; } }else{ //将文件加入zip对象 $file = $path."/".$filename; yield $file; } } } closedir($handler); } }

public function anyZip(){ for($i=0;$i<6;$i++) { $start = microtime(true); $toPath = 'D:/unzip'; $this->zipFolder($toPath, 'd:/zip/123.zip'); $end = microtime(true); echo '|zipFolder-delay:' . ($end - $start); $start = microtime(true); $toPath = 'D:/unzip'; $this->zip($toPath, 'd:/zip/124.zip'); $end = microtime(true); echo '|zip-delay:' . ($end - $start) . '
'; } }
