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?
