Hi,
recently I discovered that there are now packages for the php-oci8 module: https://blogs.oracle.com/linux/connect-php-7-to-oracle-database-using-oracle-linux-yum-server
And the PHP version is newer than RedHat's packages, that's also nice.
But the posix extension seems to be missing, or I am too dumb to find it.
`php -m` shows no posix, `yum search php- | grep posix` finds nothing, and `php -r 'echo posix_isatty(1);'` doesn't work.
