First and foremost, we recommend enabling SuPHP for security reasons. Please see the following article: Enabling SuPHP.

Also recommended are the following PHP settings. Please be aware of the implications of each and their effect on your scripts (i.e. may break some poorly-coded/older scripts). The php configuration file, php.ini, can be edited inside the WHM under Main » Service Configuration » PHP Configuration Editor and switching to Advanced Mode.

enable_dl = Off
disable_functions = show_source, system, shell_exec, passthru, exec, phpinfo, popen, proc_open, allow_url_fopen

Also consider enabling the Main » Security Center » PHP open_basedir Tweak.
