Difference and example of Mt_rand and Rand functions
Let's look at an example of the Mt_rand function.

function Roll () {
Return Mt_rand (1,6);
}
echo Roll ();

function Roll ($sides) {
Return Mt_rand (1, $sides);
}
echo Roll (6); Roll a six-sided die
echo Roll (10); Roll a ten-sided die
echo Roll (20); Roll a twenty-sided die
Let's look at an example of the RAND function.

function cn111 () {
Return rand (1,6);
}
Echo cn111 ();

One difference between these two functions is that the mt_rand efficiency is high to Rand.
