I am creating random invoice number with following.

srand((double)microtime()*1000000);
$invoicenumber=rand(10000000,99999999);
echo "$invoicenumber";

 looks like so far it is doing the job, but Is this the right way..

thanks

Depends on exactly what you want to do. Do you just want a number to show the user? Or do you want a number to show the user and put in a database? All you seem to be doing is displaying it.

Also, in PHP versions later than 4.2, there is no need to call srand().

But if it is doing the job, is it not the right way for you? :-)
