Hello All,
Many ones wanted my “Gmail Addressbook Grabber” code. I was expecting to finalize a class of that code. At last I completed that and today got approved at “planet source code”.

Please follow this link to get the “Gmail Addressbook Grabber” code:

Source Code Here

Please let me know if anything is problematic with the code. Any comments and suggestions will be highly appreciated.

Also rate this class if you like.

We started our services at phpResource Group. A subdomain has been fixed for this phpResource Services. From now on, http://services.phpresgroup.org will contain phpResource services. For the first time, we deployed the HTML2PDF and HTML2PS service. You can access these services from http://services.phpresgroup.org/pdf/url2pdf/ OR by using cURL. I have put a cURL based class in the phpResource Files Section. Download and see the url2pdfreport.zip file if you want to use this service. This service gives a exact PDF output of an HTML.

There are many security issues for session in PHP. I got two good links. Both stated about thess security issues. You can read these:

http://www.webkreator.com/php/configuration/php-session-security.html
http://www.sitepoint.com/blogs/2004/03/03/notes-on-php-session-security/

Since security is the topmost important thing in web, we need to know a bit more about security.

Enjoy PHPing !!

I just got my class “Graph Coloring” nominated at phpclasses.org for the month of May, 2006. I am enjoying the times very much after getting this good news from PHP Classes authority.

Please see this class and vote me. This class implements a completely new graph coloring algorithm designed by me.

========== Read Me ===================================

What’s graph coloring:

In a connected graph (where vertices are connected e.g. no isolated vertex exists), graph coloring is the process that ensures proper marker (/color) has (/have) been assigned to a vertex so that no adjacent (connected) vertices hold the same marker (/color).

How this class works:
This class implemented a new algorithm of graph coloring. The present class works as follow:

1. Gets graph from source (file OR DB)
1. Represents the graph (connections as well) as an array
2. Traverses the array to color vertices according to the algorithm
3. Displays the color result

The New Graph Coloring Algorithm:

The new approach of graph coloring works as follow:
======================================
graph = graph array
i=1
j=1
while(i<=no_of_vertices)
while(j<=no_of_vertices)
if (graph[i][j]==1)
i. color vertex i, push it into the colored array
ii. process(i)
else
graph[i][j]:= 0;
endif
6. j++
End of while
7. i++
End of while

—————————————–
function process(j)
i=1
while(i<=no_of_vertices)
if(graph[j][i]==1)
(i). graph[j][i]:=0 //Disconnects the colered vertex j from its connected ones — duplex disconnection
(ii).Disconnects vertex i(which is connected to the newly colored vertex j)from its connected ones–simplex disconnection
endif
End of while

end of function
====================================

I am not giving the complexity analysis of this algorithm here. Future versions will come with so.
