when I come to this step:/etc/php5/apache2/php.ini

max_execution_time = 30
memory_limit = 128M
error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
display_errors = Off
log_errors = On
error_log = /var/log/php/error.log
register_globals = Off

I can't find the :register_globals = Off
but there're
http://php.net/auto-globals-jit
auto_globals_jit = On

http://php.net/register-argc-argv
register_argc_argv = Off

should I set the both ??

Thanks in advance

The 'register_globals' directive was deprecated in PHP 5.3 and removed in PHP 5.4: http://php.net/manual/en/security.globals.php

The 'auto_globals_jit' can save a little bit of time and overhead by not creating the $SERVER and $ENV variables unless you reference them.

The 'register_argc_argv' directive is used when running PHP from the command line. If you're going to do that then it should be turned on.

Thanks
