How to Use PHP Improved MySQLi extension (and Why You Should)
In a Debian (or Ubuntu) server, the following command is enough: apt-get install php5-mysql In a Centos (or Red Hat) server: yum install php-mysql Detailed instructions for any operation system are available here. Below I describe the common use of MySQLi in php development with MySQL database (it can be also used with MariaDB, an enhanced, drop-in replacement for MySQL)
PHP: time - Manual
This is extremely important if you have multiple servers across different countries, and you want to run all of them using UTC+0 without worrying about the particular time zone in which the server is located. In other words, it will return "3 days, 2 hours, 6 minutes, and 2 seconds ago" instead of "3 days ago."Please bear in mind that it is intended for times that are very close together

Since the last login is to be updated only if an hour or more has passed since the last login this was a big problem!The problem is that PHP takes DST into account and MySQL does not (as far as I know) and I was entering the time using MySQL's NOW() function and then comparing the value returned by PHP's time() function.A very simple solution to this is the following
Consequently, to convert a time to seconds, you must multiply by the number of seconds in a day - it is easier to remember this as *24*60*60 rather than the actual number (86400)
