How to get random with beta distribution in PHP 7?

I am trying to get random number with beta distribution in PHP 7. I found function stats_rand_gen_beta, but when I was trying to install it by command:

sudo pecl install stats

I obtained the following error

WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
pecl/stats requires PHP (version >= 5.3.0, version <= 5.6.99), installed version is 7.0.14-1+deb.sury.org~xenial+1
No valid packages found
install failed

How to handle with this? Is there any replacement for stats, or other method to simply generate random with given distribution of probability?

Solution

I solved this problem checking website https://pecl.php.net/package/stats. There was written, that I should install second version of this package https://pecl.php.net/package/stats/2.0.3

O this blog I found instruction of installation.

Problem is fully solved.

Update

Finally i do not use stats, because I had problem with generating the same number any time.

I found great library:

https://github.com/gburtini/Probability-Distributions-for-PHP

Instalation:

composer require gburtini/distributions

Usage:

require_once "vendor/gburtini/distributions/src/gburtini/Distributions/Beta.php";

$a = 1.1;
$b = 9.3;

$beta = new \gburtini\Distributions\Beta($a, $b);
$res = $beta->rands(20);

var_dump($res);
