[PHP] - Lets kill the complex IF
Programming
|
Hi ya guys,
Have you ever nested that many if conditions that your code starts to get quite complicated? Let's give you an example
Just some simple data checks on the $_POST['name'] value. But I'm not happy with that code. For something so simply, why is the code so complex? Let's use a technique with functions to make this much simpler. Then explain how it works in regards to simplifying it.
[code language='php']function get_name() {
//make sure it's set
if (isset($_POST['name']) == false) {
return 'Error Occured'; View In Full

How to use Memcache on Windows
Web Development
|
I will quickly run you through an example of HOW to use memcache and how it works.
Download Memcache
http://jehiah.cz/projects/memcached-win32/
And load up the .exe - you should just get a blank command box appear - the server is then running on localhost:11211
Install the Memcache extensions in to PHP
If you use something like xamp or easyphp - just enable the memcache exentions (just a case of maybe uncommenting a line or ticking a box like in easyphp).
Code Example
Put that code in a .php page (remember to have the memcache server running). Now simply run the script and it will save my name in memory for 60 seconds! To retrieve the value from memory now put this in the script (within 60 seconds else it will expire from memory).
And you will see that my name is still there!
It's quite simple really. You use add() to add new values to memory where they are View In Full

PHP Sessions = Member Database Cache
Web Development
|
Let�s go over what a session is.
Sessions
First you call session_start() which gives you a unique ID such as: dde2ds2g67xs2zxjh89s3j8923
Everything you then save to $_SESSION is saved in a file on the server such as:
$_SESSION['message'] = 'hello';
Would be saved to:
tmp/phpsess_dde2ds2g67xs2zxjh89s3j8923
and next time you call session_start(), $_SESSION['message'] will still exist and will have 'hello' in it!
Database Problem
So, you record a members total page hits on your site, and the last time they made a page hit on your site. You keep these stats up to date like this (which is executed on EVERY page hit by the member):
$time = time();
mysql_query("UPDATE `members` SET `timestamp_last_seen` = '{$time}', `hits` = `hits` + 1 WHERE `member` = 'VBAssassin' LIMIT 1;");
Now, all you�re doing is keeping track of the last time they were seen, and the total page hits they have made while logged in.
Solution
You need to keep track of your active sessions u... View In Full

Lets say you have 5 books... and 5 people rate each of those books. Now you want to find out who's interests, based on each users 5 ratings, are similar to who?
That's what this algorithm calculate

Hey!!
Thanks for your comment!! The Matrix screensaver is not that great. It is easier than you think to make one. Just use your brain.
I am working on a 10 times better version of that moria game. I code it as a GUI this time.
I will post it here when it is finish..
And soon I will post the database program. I just need to finish it first. I am 5/7 finish.
I have seen a lot of your VB programs here. I understand that your name is not randomly selected. You have many great skills!
I just wish there could be some more C++ programmers here that actually posted some code too. I have only seen one C++ code except my own codes..
But time will probably fix that problem..
