[Tutorial] How to generate a random number in PHP

Hello!

Here is some basic tutorial on how to generate a random number in PHP.

Random numbers in PHP are generated using the rand() function. Let's write some code that will generate a random number between 1 and 10.

<?php
echo rand(1, 10);
?>

If you need more than one random number generated, use rand() function in a loop. Here is a code for generating three random numbers between 10 and 20.

<?php
for ($i = 0; $i < 3; $i++)
{
    echo rand(10, 20) . " ";
}
?>
