Random Number, Should be easy!

[Snooble]

<?php 
$_SESSION['point'] = rand(0, 10).".". rand(0, 9) rand(0, 9); 
echo $_SESSION['point'];
?>

 

I want to set a variable (SESSION OR NOT) to a random number. The number needs to be 2 dec places. so i've used 3 random numbers. ?????

 

how can i get it to work? The idea is to add the amount to a mysql cell (easy enough i believe) and then echo the cell out.

 

number should look like this : *.** in the sql table.

 

so: 3.91 or 1.27

 

etc.

 

Thanks,

rand(0, 10) should also be rand(0, 9) since you want it in the *.** format, and btw, what is your problem?

blank page.. parse

 

yes thanks, but i can do that. Just need to set the number to a variable and echo it out.

 

Thanks

do you have the start session at the top? and try:

<?php 
$_SESSION['point'] = "".rand(0, 10).".".rand(0, 9)."".rand(0, 9).""; 
echo $_SESSION['point'];
?>

instead.

lol duh... i didn't have start session at the top, it still gave me a parse, used your code and all works. Thanks,

 

Seem like an expert to me! Keep up the good work! Thanks
