OCI8 is the most available and scalable PHP adapter for the Oracle database. It is included with PHP, and is also separately downloadable for upgrading older PHP releases. OCI8 works with PHP 4 and PHP 5, and will compile with Oracle 9iR2, 10g and 11g client libraries. Oracle's standard cross-version compatibility and connectivity is applicable, so an OCI8 binary can connect to older or newer databases, locally or remotely.
The latest OCI8 release includes support for Oracle Database 11g Database Resident Connection Pooling (DRCP), and for Fast Application Notification (FAN) (whitepaper), and also has support for Oracle's authentication and end-to-end tracing meta data attributes (article). These features improve scalability and availabilty of the OCI8 extension.
Oracle Database Express Edition (XE) - an entry-level, small-footprint database based on the standard Oracle Database code base that's free to develop, deploy, and distribute; fast to download; and simple to administer.
MySQL - The world's most popular open source database. MySQL Community Edition is the freely downloadable version. Commercial customers have the flexibility of choosing from multiple editions to meet specific business and technical requirements. Also available for free is the MySQL Workbench for SQL Authoring, System Administration, and schema modeling.
Oracle Berkeley DB 11g - provides the complex data management features found in enterprise class databases. These facilities include high throughput, low-latency reads, non-blocking writes, high concurrency, data scalability, in-memory caching, ACID transactions, automatic and catastrophic recovery when the application, system or hardware fails, high availability and replication in an application configurable package. Simply configure the library and use the particular features available to satisfy your particular application needs.
NetBeans IDE - lets you develop desktop, mobile and Web applications using Java, PHP, C/C++ and more. Runs on Windows, Linux, Mac OS X and Solaris. NetBeans IDE is open-source and free.
Oracle VM VirtualBox - powerful cross-platform Virtualization Software for x86-based systems. "Cross-platform" means that it installs on Windows, Linux, Mac OS X and Solaris x86 computers. And "Virtualization Software" means that you can create and run multiple Virtual Machines, running different operating systems, on the same computer at the same time. For example, you can run Windows and Linux on your Mac, run Linux and Solaris on your Windows PC, or run Windows on you Linux systems. Oracle VM VirtualBox is available as Open Source or pre-built Binaries for Windows, Linux, Mac OS X and Solaris.
OTN offers some pre-built Developer VMs, including an Oracle Tuxedo Web Application Server VM showing PHP support. There is also a Zend Server VM for PHP created by Zend. Zend Server is a complete, Oracle-enabled, enterprise-ready Web Application Server for running and managing PHP applications that require a high level of reliability, performance and security. Zend Server is available in community and supported editions.
Oracle Linux - free to download and distribute. As one of the most widely deployed operating systems today, Linux is increasingly being adopted for cloud-based solutions. Oracle Linux is the most complete and integrated solution available and delivers higher performance and better reliability at up to 7 times lower cost than Red Hat. (Why Choose Oracle Linux over Red Hat Linux?) Oracle Linux 5.6 and 6 introduced PHP 5.3 packages; subscribers to the Unbreakable Linux Network have access to an additional pre-built PHP OCI8 RPM, and also direct access to an RPM for installing Zend Server.
Oracle Tuxedo - provides a robust, grid enabled platform for developing enterprise applications. It provides mainframe-class scale and performance on open, distributed systems for software written in C, C++, COBOL, PHP, Python and Ruby. Oracle Tuxedo provides cost-effective reliability, extreme scalability and throughput of hundreds of thousands of transactions per second. Functionality like Web services, SCA programming model, metadata driven application development make it simple to develop and integrate applications written in many programming languages. PHP applications can be hosted on the Tuxedo platform without requiring any code changes and can leverage high availability, scalability and integration capabilities.
Oracle Instant Client - a small footprint set of libraries that allows applications and tools to connect to an existing Oracle Database. Oracle OCI, OCCI, Pro*C, ODBC, and JDBC applications work without modification. The PHP OCI8 extension can be built with Oracle Instant Client to connect to a remote database; Instant Client is provided under a separate OTN Development and Distribution License that allows most licensees to download, redistribute, and deploy in production environments, without charge.
