Question

I am using the following code

$wID=rand(2, 4); 

to generate numbers from 2 to 4, how can i generate numbers starting from 2 but no maximum?

Answer 1

Use mt_rand (it’s better).

how can i generate numbers starting from 2 but no maximum?

No computer can produce an infinite set of numbers.

If you call mt_rand without arguments, it will return a number between 0 and the value of mt_getrandmax(). So, if you want, you can do:

$wID = mt_rand() + 2; 

or:

$wID = mt_rand(2, mt_getrandmax()); 

or just enter a very high max of your choosing.
