Using Digits also for();

[MemphiS]

First question:

 

i wish for my data in the db to be placed in as 0.00..

Currently im doing this:

<?php
$po = 4; // actual figure comes from the database..
$po1 = 100; // actual figure comes from the database..
$rand1 = rand(0,$po);
$rand2 = rand(0,$po1);

$overAll = $rand1+".$rand2";

output: 2.78 // Example...
?>

 

Is there a better way of doing this? im sure there is

 

My other question is:

 

I wish to do the following:

 

Example:

<?php
$u1 = 200; // actual figure comes from the db
$u2 = 1000; // actual figure comes from the db
$main = 10000;

for ($i = 0; $i < $main; $i++){
$u1P = rand(0,$u1);
$main = $main - $u1P;
echo("U1 takes $u1P off main");
$main = $main - $u2P;
$u2P = rand(0,$u2);
echo("U2 takes $u2P off main");
}
?>

Now the problem with this is that it is going always go U1 first then U2.. I want it to be random so U1 could go say 10 times if U1 number is greater then U2s

 

Hope ive explained it enough for someone to understand

 

Thanks for your responces

You can use the printf()/sprintf() functions to format variables for output to the browser.

 

<?php
$po = 4;
$po1 = 99;//i assumed the max here would be 99 if its supposed to be two digits?
printf('%.2f',rand(0,$po).'.'.rand(0,$po1));//the .2 specifies 2 decimal points
?>

 

As for your second question, im not entirely sure what you mean. If you were wanted to sometimes use the u1 value and sometimes use the u2 value in your loop, you could always do:

 

<?php
if(rand(0,1)==0){
//use u1
}else{
//use u2
}
?>

 

But as i say, im not entirely sure thats what you wanted.
