Compare Statement ... maybe

[newttster]

I'm trying to find a shorter way of getting this idea to work ... I've considered arrays, elseif statements even a while loop but they would lead to well over 2000 lines of code.

This is what I am trying to implement;

If 'x'=1 then 'y'='z'*1

elseif 'x'=2 then 'y'='z'*1.2

elseif 'x'=3 then 'y'='z'*1.4

elseif 'x'=4 then 'y'='z'*1.6

elseif 'x'=5 then 'y'='z'*1.8

elseif 'x'=6 then 'y'='z'*2

elseif 'x'=7 then 'y'='z'*2.2

etc.

I want the process to check 'x' where 'x' can be a number between 1 and 2000 and that the multiplier of 'z' increases by .2 for each 'x' increase, so that if 'x'=98 then the process will pull 'z' as 'z'='z'*11.4 and so on.

Any ideas or suggestions that can point me in the right direction would be greatly appreciated. Thanks.

Something like this i think;

 

$z = 5; //for example
$y = 1;
for($i = 1, $add = 0.2; $i <= 2000; $i++) {
$y = ($i == 1) ? $y : $y+$add;
if($i == $x) {
$y = $z * $y;
}
}

y=z*(((x-1)*0.2)+1)

That work?

Wouldn't a Case work aswell? Or am I wrong.

 

Edit: nvm, did not read it properly.

@Danny696 ... I tried your idea and unfortunately I couldn't get it to work the way I need it too. Thank you for your suggestion just the same.

@Dayo ... if you were close by ... I'd kiss you. :P Your suggestion works perfectly. Thank you very much.

No problem mate ... Algebra was my strongest subject in maths :) did you need the PHP code?

[newttster]

Thanks Dayo ... I think I have it so far. I'm just setting up my "mock" tables and such first then I will give it a more in depth test to make sure it all works the way I need it to.

Would you like to see it when I have it all set up?
