Implement an efficient and secure ftp server using PHP (1)

: This article mainly introduces how to use PHP to implement an efficient and secure ftp server (1). If you are interested in the PHP Tutorial, refer to it. Abstract:

This article mainly describes how to use the swoole extension of PHP to implement ftp servers, while also extending the ftp server's personalized functions and security. Implement an ftp server that is fully controlled by you and customize the ftp server.

Body:

The FTP server must be familiar to everyone. There are also a lot of ready-made software to use. However, free software features sometimes do not meet your needs and cannot be developed again. The price of paid software is high. The swoole extension of PHP is a high-performance network communication framework of PHP. It provides PHP asynchronous multi-threaded servers, asynchronous TCP/UDP network clients, asynchronous MySQL, database connection pool, AsyncTask, and messageQueue, Millisecond timer, asynchronous file read/write, asynchronous DNS query.

Swoole can be widely used in the Internet, mobile communications, enterprise software, online games, IoT, IoV, smart home, and other fields. Using PHP + Swoole as the network communication framework can greatly improve the efficiency of enterprise it r & D teams and focus more on developing innovative products.

Swoole has built-in asynchronous non-blocking and multi-thread network I/O servers.PHP programmersYou only need to process the event callback and do not need to care about the underlying layer. With Nginx/Tornado/Node. jsSwoole supports both full asynchronous and synchronous architectures.

With this foundation, it is easy to develop TCP/IP-based servers. You may ask why PHP can be used in C # and other languages? I want to focus on development efficiency. PHP is a script language without compilation, and development and deployment are fast.

The steps are listed here:

00 preparation platform, I use CentOS7 here;

01 to install php and swoole extensions, see http://wiki.swoole.com/wiki/page/6.html;

02 set the character set. Because ftp files are prone to garbled characters, we recommend that you set the character set of the operating system to GB18030, which is consistent with that of Windows. Currently, most ftp clients support utf8 file name encoding, however, the usage is not satisfactory. Thank you very much for choosing the solution;

03 compile the php program and test the php program;

04 deploy the ftp server for php.

The functions of the ftp server are as follows:

* User and group management; * self-help password modification and resetting; * folder permission management; * IP address access control; * online user viewing; * viewing disk space usage; * SSL support, protect the transmission security of passwords and files. * The built-in web management page facilitates remote management.
