The correct function would be file_exists. If you look on the PHP resources (i.e. filesystem functions PHP: Filesystem Functions - Manual) you will find a breadth of functions to work with files.

You can as well type php.net/(function name here) to access its usage page as a shortcut, there are some neat resources online for PHP.

You can check if they have the MySQL module loaded, in case they have set it up themselves:

if( !extension_loaded("mysql") ) {
   //MySQL not compiled with PHP, or not loaded
}

Although rarely it is not installed or bundled, so you can simply check if it can be connected to with mysql_connect(). The manual says it returns false on failure so you can check for this.
