background

In this paper, php OSS File read and write files ,workerman Generate temporary files and export them to the browser for download

 

php Document operation introduction

• fstat function ： Show all the information about the file
• File read ： fread($fp,filesize($file_path));
• write file ：file_put_contents($file_path,$con,FILE_APPEND);
• Application of file operation ： Can operate ini file . Write the configuration of the server in ini In file , And then operate it .
• Copy files ：copy("e:\2.txt","d:\1.txt")
• Create folder :mkdir($path,0777,true)

 

workerman Introduce

Workerman It's a pure PHP Developed open source high performance PHP Application container .

Workerman It's not about making wheels over and over again , It's not a MVC frame , It is a lower level and more general service framework , You can use it to develop tcp agent 、 Do game server 、 Mail server 、ftp The server 、 Even develop a php Version of redis、php Version database 、php Version of nginx、php Version of php-fpm wait .Workerman Can be said to be PHP An innovation in the field , Let developers get rid of PHP Can only do WEB The bondage of .

actually Workerman Like a PHP Version of nginx, The core is multi process +Epoll+ Non blocking IO.Workerman Each process can maintain tens of thousands of concurrent connections . Due to its resident memory , Do not rely on Apache、nginx、php-fpm These containers , With super high performance . Support at the same time TCP、UDP、UNIXSOCKET, Supports long connections , Support Websocket、HTTP、WSS、HTTPS And other communication protocols and various user-defined protocols . Have a timer 、 asynchronous socket client 、 asynchronous Redis、 asynchronous Http、 Asynchronous message queuing and many other high-performance components .

 

Read the file

 // Read the file         header("Content-Type: text/html;charset=utf-8");    // Set character encoding         $file        = base\_path() . "/public/index.m3u8";        $read        = fopen($file, 'r');        $contents    = fread($read, filesize($file));        $string1     = getBeforeString($contents, 'enc.key');        $string2     = getLaterString($contents, 'enc.key');        $newContents = $string1 . 'enc.key?token=123' . $string2;        fclose($read);

write file

 // write file 、        $file   = base\_path() . "/public/test22.m3u8";        $handle = fopen($file, 'w');              // Open file         fwrite($handle, $newContents);             // Write content         fclose($handle);                           // Close file         readfile($file);                           // Read and output all the contents of the file         return redirect(WEB\_URL . '/test22.m3u8');// Transfer page 

Read oss file , Read each line of the file

// Read OSS file         $file = OSS\_URL . $url1;        // Add the contents of the file to the array         $fileContent = @file($file);        $newContent  = '';        // Traverse every line of the file         foreach ($fileContent as $value) {            // Whether this character exists on this line of the file , With this replacement             if (strpos($value, 'api.qingsong.chaotuapp.com/') !== false) {                $value = str\_replace('app.com/', "q.com/ckey", $value);            }            // Whether this character exists on this line of the file , There is this splicing content             if (strpos($value, '.ts') !== false) {                $value = $ossUrl . $value;            }            $newContent .= $value;        }

Temporary file write , Generate temporary files and download them from the browser

wokerman frame

// write file         $fileName = "$token.m3u8";        // ./59ee8147cf3f42575bc91ff586d54837.m3u8        $file = "./$fileName";        // Open file         $handle = fopen($file, 'w');        // Write content         fwrite($handle, $newContent);        // Convert file to string         $content = file\_get\_contents($file);        // Delete temporary files         unlink($file);        // Output browser         $response = new Response();        return $response->withHeader('content-description', 'File Transfer')            ->withHeader('content-type', 'application/force-download')            ->withHeader('content-disposition', "attachment; filename={$fileName}")            ->withHeader('content-transfer-encoding', 'binary')            ->withHeader('pragma', 'public')            ->withBody($content);
