What Is a Random Number Between 1 and 20?

A random number between 1 and 20 is an integer chosen without bias from all values within that inclusive range. In this case, the number 11 was selected randomly from the set of integers starting at 1 and ending at 20.

How Are Random Numbers Generated in PHP?

In this tool, we use the built-in rand(1, 20) function in PHP. This generates a pseudo-random integer between the lower limit 1 and the upper limit 20, inclusive. The randomness is sufficient for simple utilities like this, but for cryptographic or security purposes, more robust randomization (e.g., random_int()) would be needed.
