The PHP 7 compatible OCI8 2.1.7 for Oracle Database is now on PECL
This version of OCI8 will also be bundled in PHP 7.0.23 and PHP 7.1.9 (and is already in PHP 7.2.0beta2). Older PHP 7 installations can be brought up to date using the PECL bundle.
The highlight of this release is Transparent Application Failover (TAF) callback support, giving applications better control in High Availability database deployments.
