PHP Shell is a shell wrapped in a PHP script. It's a tool you can use to execute arbiritary shell-commands or browse the filesystem on your remote Web server. This replaces, to a degree, a normal telnet-connection. You can use it for administration and maintenance of your Web site using commands like ps, free, du, df, and more.

PHPsh allows you to have shell commands run on your behalf by Web servers that serve PHP pages, and solves these issues and more. It is a simplified version of the shell that allows you to execute arbitrary commands remotely through PHP. It is a handy way to run simple commands and maintain a history of executed commands, and a helpful environment that allows you to browse the filesystem and fetch or upload files.
phpRemoteShell is an all-in-one Web application to manage servers remotely. It contains a full-featured file manager, the ability to execute shell commands or code written for PHP, SQL, or LDAP, a crontab manager, and a zombie manager. It can also host itself into existing files and auto-deploy during their execution. In case it has been previously encrypted, it is able to self-decrypt on the fly.
