[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

hey..can you teach me visual basic??

Don't know if you still check your comments but I'll leave one regardless.
Like the guy below me, I stumbled back across CoderProfile and remembered how much I
used to love it. It's a shame it's been sitting here for the past three
years or so doing next to nothing.
I'm going to try and get in touch with you via AIM/Email about getting it
going again. If you don't have the time I'd be happy to lend a hand.
Promotion work and the like. Obviously the sites still fully functional but if a
website isn't updated regularly (news posts, forum activity, etc) by the admin,
it puts me and probably others off slightly.
I think you've got a great, fairly unique idea here that could get quite big.
It'd be a shame to see it fade away.

Hey Scott! What's been goin on? I came back and it looks like this site is all
dried up... a real shame, this site had a lot of potential, was amazing as is, and
heard more was to come! Any plans on reviving the website? I wouldn't mind
getting my friends in here and helping promote the site if you were going to revive
it. Would be cool man.

Hey, I have finally returned and it looks like this pretty dead now. That's a
shame because this site really had a lot of potential. I hope you attempt to revive
it someday. :(
|
|
|
What's the timeline for all this?
|
|
|
So, has this been completely abandoned?
|
|
|
Damn Scott, this site needs an update!
|
|
|
Yea the following system will be very useful, so I can't wait to see that in all
its glory. :)
We talk soon mate!

Hey,
Thanks for keeping me in the loop. Just checked it out, and it looks great. I
won't be using the class until i wrap my head around the binary system and
bitwise stuff, as I don't like using stuff i'm not confident with. :)
Thanks man!
