You cannot run BeBot on a web hosting site that offers PHP and MySQL.
You must have full shell (Linux, UNIX systems) or console (for Windows) to run BeBot.
BeBot is written in PHP but it is not a web application. Like Python, Perl, and many other interpreted languages, PHP can be invoked multiple ways. The most common way is via a web server where the webserver runs the PHP code and displays HTML output.
For BeBot, we use the command line method and output goes to the console. BeBot requires sockets to function. Any sane webhost will have php sockets disabled. This alone will prevent you from running BeBot as a webpage.
On a Unix system, you should be able to run the command:
which php
or
which php5
To get the full path the php executable.
