PHP Random Numbers

The rand() function is used in PHP to generate a random integer. The rand() PHP function can also be used to generate a random number within a specific range, such as a number between 10 and 35.

If no max limit is specified when using the rand() PHP function, the largest integer that can be returned is determined by the getrandmax() function, which varies by operating system. PHP random numbers

Random Number Syntax :

rand(min, max);

The rand() funciton generates a random number:

Example

<!DOCTYPE html>
<html>
<head>

<title>PHP Random Numbers</title>

</head>
<body>

<h1> </h1>

<?php

echo (rand(10,35));

echo "<br>";

echo (rand(1, 100000));

echo "<br>";

echo (rand());

</body>
</html>

As you can see in these examples, the first rand function generates a random number between 10 and 30, the second between 1 and 1 million, and then third without any maximum or minimum number defined.
