# How to Generate a Random Number in PHP

To generate a random number in PHP, we use the **mt_rand** function.

The general form to generate a random number is:

**
$random_number= mt_rand( minimum_number_range, maximum_number_range);
**
where

*minimum_number_range*is the minimum number value that the

**mt_rand**function can generate

*maximum_number_range*is the maximum number value that the

**mt_rand**function can generate

The **$random_number** variable stores the random number which you generate from the **mt_rand()** function.

For example, if you want to generate a random number from 50 to 70, the minimum number range would be 50 and the maximum number range would be 70, because you want to generate a random number between 50 and 70.

### Example

To generate and display a number from 1 to 100, the code to do this is:

$random_number= mt_rand(1, 100);

echo $random_number;
