 There are two reasons why this situation is unsatisfactory. First, PHP programmers should be able to write scripts that use CS random data without risking failure in the field due to unfortunate configuration of the production environment. The programmer, after all, may have no influence over the production environment and might not be in a position to dictate requirements. Nevertheless, the programmer may want to protect her reputation by delivering quality software that can reasonably be expected work securely many years into the future on PHP systems of configuration she cannot predict. There are two reasons why this situation is unsatisfactory.

-Second, even if the probability that all 5 of the methods described above fail were vanishingly small, such a process is unacceptably complex. It demands a degree of sophistication and volume of code that is out of keeping with the task—it should be as simple as calling a function similar to openssl_random_pseudo_bytes(). More importantly, it is difficult to test such software because it requires many different runtime systems to exercise all braches. +Second, even if the probability of failure of all 5 of the methods described above were vanishingly small, such a process is unacceptably complex.
