Creating a random number takes two commands called srand and rand. srand is a preparation command for rand. It helps rand create a truely random number. rand itself creates the random number. To make a random number within a specific range, you can add the number range in the rand command brackets.

To create random numbers in PHP, you can use the rand() function call, which takes either zero or, optionally, two parameters determining the minimum and maximum random numbers (inclusive) that you'd like. If you don't specify a maximum then it will default to a value, RAND_MAX, set in the PHP configuration. The function returns an integer, generated "randomly." (Computers can't generate real random numbers, but this tries and is suitable for most purposes.)
