how to download a file without display download request
Usually when we try to download something from a server we get a confirmation request whether you want to save the file or open it.
To avoid this request you can use the below code and then user can directly download that file without any message.
First give a link or a button for user to download and when they click redirect them to a file which will have the code below.
suppose you want user to download a pdf file then first make a link like this:
<a href=”javascript:void();” onClick=”location.href=’doc/document_download.php’”>download pdf</a>

Sessions in php
I always try to provide good information to beginners in php because these small looking problems may be big problem for a beginner. Session are one of them.
We use sessions when we get to a stage where our website need to pass along user data from one page to another.
A normal HTML website will not pass data from one page to another. In other words, all information is forgotten when a new page is loaded. This makes it quite a problem for tasks like a shopping cart, which requires data(the user’s selected product) to be remembered from one page to the next.
Using session you can send information between one page to another.However, this session information is temporary and is usually deleted very quickly after the user has left the website that uses sessions. Sessions work by creating a unique identification(UID) number for each visitor and storing variables based on this ID. This helps to prevent two users’ data from getting confused with one another when visiting the same web page. Read the rest of this entry »

Arrays in php
Arrays are always a big and typical topic for php beginners.Some times they left their job because of arrays.I was also one of them .But after a long experience now i understand that arrays are too easy in php like eating food because php has allready provided readymade funda for arrays .You just have to use that logic and nothing else.
An array in PHP is a collection of values. Like A map that associates values to keys. In an array each values associate to an Unique key and you can access valuse by using that key. As array values can be other arrays, trees and multidimensional arrays are also possible.
