Last Updated on Feb 15, 2023
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.
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
Now you know about random numbers in PHP.
I recommend you to open a PHP files and generate some random numbers. generate numbers with decimals as well.
