Today we are going to talk about generating random numbers in PHP. Knowing how to generate a random number is more useful than you think. you can select random users and much more.

It’s very easy to generate random numbers in PHP.


All you need is this function



rand(min value, max value);

Let's see some examples:

echo rand(1,100);
// 46
echo rand(1,100);
// 73

Random Number with Decimals

Both min value and Max value must be int so what if you wanted to generate a random number that is not int.


Super easy!

Generate the random number and then divide it by 100


// Random number between 0 and 1
echo rand(1,100) / 100;
// 0.56

// Random number between 4 and 5
echo rand(4,500) / 100;
// 4.75
