[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

Randomly pick an element out of an array, returns what was picked and removes the picked element from referenced array.
P.S. I've only been learning Perl for about 8 hours... so don't tell me off i

Specify an array of settings, and depending on the combination of settings will return a unique integer. This integer can then be used to workout the settings that were selected to produce that intege

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

Yea man sounds good. I had a slight tingly pain running through my arms, but I jumped
in early and started going to the gym, they are getting better too. Lucky I got in
early though, thanks to you I'm aware of the risks. I hope that didn't
sound emotionally lifeless, because i didn't mean for it to sound that way.
Your new system sounds really cool. Will you release concepts and little snippets
and ideas of various working parts?
Cya Bud.

Hehe thanks for the tip. Your CMS to build websites definitely does sound
interesting. So I know that business always comes first but do we have a timeline
when work will start again on CP? :)

Hey buddy,
I've been good, currently working at an email marketing place building HTML
Email templates, which gets quite boring since all i think about while i'm there
is coding PHP. However I've purchased a CMS from someone and I'll be
rewriting the script since its all in procedural code and not too crash hot. So yea
lots of stuff brewing in my world, how about yours?
Thanks,
Tom

Ah yeah, well i think i might crack on with some php. Not too sure yet, but most
probably will :)
Just, haven't a clue what to code yet :P
|
|

Ah i see, do you mean like i didn't learn enough about programming itself, not
the actual language?
And aha, i would hate that, somtimes i go for around 2-3 hours with no break.
I am currently learning PHP again, and i will then be using miniPHp (google it) it
looks sweat. I have used it before. And i will develop things with it, such as a
editor. And i may even give an irc client a go, if its up to it :P
I don't have much time anymore as last year of school so kinda stuck on
things. GF takes up time in my life too :P so yeah.
Other than that i do my gfx and all :D

Hmmmm, i haven't been around here in a while have i :O
Not much difference, don't worry i know about your hand problems, hope they
are getting better.
I don't do much coding anymore :( Unfortunately. But i decided i do not have
the skill to learn it, yet. My creativity skills are alot better, meaning im'
better at graphics :).
That can get me just as far :) Check out my dA http://asketch.deviantart.com/
Anyways,
How have you been in general? Apart from your hand problems.
