PHP pseudo random number and true random number detailed, pseudo random number detailed
The first thing to declare is that the computer does not produce an absolute random number, and the computer can only produce "pseudo-random numbers". In fact,

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
One. In J2SE we can use the Math.random () method to produce a random number, the resulting random number is a double between 0-1, we can multiply him by a certain number, for example, multiplied by 100, he is a random within 100, this is not in the
