i18n All-in-one format and timezone conversions for date, time, timestamp and datetime.

Updated a day ago by Gerhard LiebenbergHow-tos3 comments – viewed 11,641 times – ( +7 / -1 ) – version 1.1
Countries sometimes change their laws pertaining to timezones and daylight saving times. This means that GMT+2 can be a different time this August compared to last August! However, by using php's DateTime class (instead of timestamps), we can do both "format" and "timezone" conversions on a single DateTime object (only 2 lines of code) for date, time, timestamp and datetime types - while php takes care of nightmares such as current and historical timezones and daylight saving times.

Yii configuration: Dynamic & User dependent

Updated 7 days ago by le_topHow-tos0 comments – viewed 1,264 times – ( +1 ) – version 1.1
It is difficult to perform user dependent theming through a general configuration in 'main.php'. This article proposes a method to do so through a Factory that dynamically generates classes to allow delayed resolution of actual user values. This means that you can refer to values that are stored in the database through the CActiveRecord before Yii is actually loaded. The values will be fetched from the database when actually used for the first time, which is after Yii is loaded. Actually, you can use pretty much any method that relies on Yii with this method.

How to hide /frontend/web in url addresses on apache

Updated 29 days ago by raminiousHow-tos8 comments – viewed 25,299 times – ( +9 ) – version 2.0
There is an issue on Yii2 to redirecting / urls to /frontend/web. In other words we need a way to hidden /frontend/web from addresses. We will do this without changing Apache configuration and creating virtual host or setting document root (It's good for share hostings that we have not access to apache.conf)
