i install sockets module with source code.
/../php-5.6.24/ext/sockets/
/opt/php/bin/phpize
./configure --with-php-config=/opt/php/bin/php-config --prefix=/opt/php --enable-sockets
make && make install
add to php.ini
extension="/opt/php/lib/php/extensions/no-debug-non-zts-20131226/sockets.so"

/opt/php/bin/php -m
but it not found in phpinfo, and can not use function socket_create().
