At the time of writing, most Linux distributions ship their PHP versions with sockets enabled by default.
Tested distros/versions:
CentOS 7, PHP 5.4: Enabled;
CentOS 7, Remi repo, PHP 7.1.1: Enabled;
CentOS 7, DirectAdmin Custombuild, PHP 7.0.9: Enabled;
CentOS 7, DirectAdmin Custombuild, PHP 5.6.24: Enabled;
Debian Jessie, PHP 5.6.30-0+deb8u1: Enabled;
Gentoo Linux ~amd64, PHP 7.1.1: Enabled (USE-flag "sockets" is enabled by default)
Alpine Linux: PHP 5.6.30: Disabled, however this can simply be enabled by installing php5-sockets
I haven't tested other distros/versions, but as far as compatibility goes most systems seem to support sockets out of the box.
Installation
The socket functions described here are part of an extension to PHP which must be enabled at compile time by giving the --enable-sockets option to configure.
