RE: [PHP-DEV] [RFC] Add Random Extension (before: Add Random class)

These two methods confused me at first as well, but I think it's ok with me after I check the documentation of mt_rand(), which also supports calling without range. So, compatibility is one of the reasons why this method exists, although I still feel we should find a better name for them. They are too similar now, you won't be able to tell the difference without looking into the documentation or source code. Besides the name issue, I have another question for nextInt(). What's the range of its return? It's not clear in the RFC. The range of mt_rand() (without min and max) is 0 to mt_getrandmax(), so how about nextInt()? is there any equivalent method/constant for it? Regards, CHU Zhaowei
