Change php.ini and reload nginx does not update value

Error: "Parse error: syntax error, unexpected end of file in..." (it works on old server, i do not change any code)

Reason: short_open_tag = Off

Solution:
Note: prepend sudo if not root

Open /etc/php5/fpm/php.ini, change value to On
Restart php5-fpm instead of reload nginx
/etc/init.d/php5-fpm restart
