[Resolved] Any one know a function for numbering?

[airric]

I need to generate an order number for a shopping cart.

any Ideas?

For now I am using a ramdon mumber generator but I'm afraid it will produce the same number at some point!

here is what I'm using:

$new_string;
srand((double)microtime()*1000000);
$string = md5(rand(0,9999));
$new_string = substr($string, 17, 10);

Hi there,
Why not auto increment the number?

Or use a timestamp - you're already using microtime(). If you want something unreadable, MD5() it. If you want a number, take the first seven characters of the MD5 and use base_convert to convert it from base 16 to base 10 (eight characters and you risk overflows).

Or at least don't restrict the random number range to only 10000 possible numbers.

I take it you mean the mysql auto increment field function ?

or is ther a function to do it in php?

the cart has each item entered in during a while statement and the fileds would all have different numbers. (with the mysql function)

do you know how I could do it with PHP?
