Complete PHP Math Reference
Definition and Usage
The mt_rand() function returns a random integer using the Mersenne Twister algorithm.
If this function is called without parameters, it returns a pseudo-random value between 0 and RAND_MAX.
If you want a random number between 10 and 100 (inclusive), use mt_rand (10,100).
Syntax
mt_rand(min,max)
| Parameter | Description |
|---|---|
| min,max | Optional. Specifies the range the random number should lie within |
Tips and Notes
Tip: This function produces a better random value four times faster than rand()!
Note: In PHP 4.2.0 and later, there is no need to seed the random generator with mt_srand(). This is done automatically.
Example
In this example we will return some random numbers:
<?php
echo(mt_rand() . "<br />");
echo(mt_rand() . "<br />");
echo(mt_rand(10,100))
?>
echo(mt_rand() . "<br />");
echo(mt_rand() . "<br />");
echo(mt_rand(10,100))
?>
The output of the code above could be:
1150905288
613289478
21
613289478
