This article mainly introduces PHP's pseudo-random number and real random number details. This article first explains the concepts related to the real random number and pseudo-random number, and gives the comparison using mt_rand () an example code

This article mainly introduces the pseudo random number and the true random number of PHP, this paper first explained the concept of true random number and pseudo random number, and gave a better pseudo-random number than using Mt_rand () function

The first thing to declare is that the computer does not produce an absolutely random random number, and the computer can only produce "pseudorandom numbers". In fact, the absolute random random number is only an ideal random number, even if the

RandomThe random class in Java generates a pseudo-random number, uses the seed of 48-bit, and then calls a linear congruential formula linear congruence equation (Donald Knuth's programming Art of 3.2.1)If two random instances use the same seed, and

Abstract pseudo-random numbers are widely used in computer software design. This article introduces a mathematical method to use computers to generate pseudo-random numbers, that is, the linear same-remainder method. Any pseudo-random numbers are
