在PHP中，无法弄清楚如何在我的最大和最小范围之间生成随机整数

Question

In PHP, I need to find a way to generate random integers between 1 and 46938003261

The rand function seems to be unable to generate numbers larger than 9 digits long, which is a problem for me given my 11 digit long max number.

rand (1 , 46938003261)

I realize this is a limitation of PHP on 32 bit systems, and I can verify that I have had the same issue using mt-rand instead of rand.

How can I generate a random integer between 0 and 46938003261 with PHP?

Thanks!

Answer 1

Append 2 numbers and concatenate them

rand (0 , 46938003261) + rand (10 ,100 ) 

But make sure you convert them to string and then add (?)

Another approach is to check the size of string before concatenating them.
