Data structures in PHP 5.3

In the programming world there are quite a few well understood and explored data structures. Which are commonly used in tons of applications, still the only things PHP offered till 5.3 in regards to structuring data were arrays (more precise: hash tables) and objects. So people had to either abuse them for other structures or implement the structures themselves on top of these. Thanks to Etienne things now are changing and PHP's Standard PHP Library (SPL) extension will offer quite a few standard implementations of data structures. The implemented data structures are implemented using these classes:

* SplDoublyLinkedList
* SplStack
* SplQueue (SplPriorityQueue)
* SplHeap (SplMinHeap, SplMaxHeap)
* SplFixedArray

Usage of IF condition in mysql

Scenario:

Suppose we have the field in the table lets say status which has the ENUM value ACTIVE,INACTIVE.Usually after getting the value of this field(through the query)

we used to write return ($result['status']=='ACTIVE')?1:0 in class methods.

Here we are getting the db result array and based on the check(ACTIVE/INACTIVE) we are returning the boolean value.Instead of that we can have that check in the query itself like below

SELECT IF(status='ACTIVE',1,0) AS statuscheck from table1

Note that in the condition we need to give single equal symbol

so the code return ($result['status']=='ACTIVE')?1:0 will be replaced by return $result['statuscheck'].

Google Turns its Back on Firefox

About a month ago, Google dropped StarOffice from the Google Pack, a downloadable package of free Internet and productivity software for Windows users. StarOffice is a desktop office suite based on the open source OpenOffice.org program and distribute by Sun, and we theorized that Google was laying the ground work for a future push to get users to dump their desktop software in favor of Google’s own web-based application offerings.
