How to disable phpinfo(); in a shared hosting

Some server administrators may choose to disable the PHP function phpinfo() for security purposes, because it shows information which can be used to compromise the server that your site is operating on.

Here are the steps to disable it.

SSH to server as a rootuser
Edit the php.ini file.

disable_functions = phpinfo

OR we can do the same within .htaccess file by adding the following line:

php_value disable_functions phpinfo

Same way we can disable other php functions in PHP.ini file:

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