Chris Jones has pointed out a video of a recent presentation at the Singapore PHP User Group Meeting done by Blair Layton (of Oracle Asia Pacific) on the OCI8 extension and using it to connect PHP.
While most PHP developers start off on the LAMP (Linux, Apache, MySQL, PHP) stack there maybe a need to investigate OPAL (Oracle, PHP, Apache, Linux). This talk will discuss what Oracle offers PHP developers including operating system, database, middleware and tools support. You will find out how to take advantage of specific features in Oracle Database 11g that assist PHP developers such as Database Resident Connection Pooling with code samples and demos. An example architecture from a USA web company of a highly scalable PHP application that uses Oracle database will also be discussed.
His slides are also available for download - Set 1, Set 2 and you can watch the full video here.
