The Sybase® Adaptive Server® Enterprise extension module for the PHP scripting language allows PHP developers to execute queries against an Adaptive Server database.
The extension module for PHP is a vendor-specific database interface driver that executes queries against an Adaptive Server database. The open source programming language, PHP (Hypertext Preprocessor) provides the ability to retrieve information from common databases. The Adaptive Server extension module for the PHP scripting language includes the necessary PHP APIs to enable PHP developers to write standalone scripts to execute queries against an Adaptive Server database.
The extension module for PHP has been tested against the command line PHP implementation. Usage of the extension, such as a CGI module in a Web server, is beyond the scope of Sybase testing.
PHP Extension Data Flow
The following diagram shows the data flow from a PHP script to an Adaptive Server database.
Required Components
Access to an Adaptive Server database using the PHP programming language requires the following components:
- PHP script – application script to connect to an Adaptive Server database server.
- Adaptive Server Enterprise extension module for PHP – is the vendor-specific driver supported by Sybase. The extension is called through the PHP script and connects to the API layer DBCAPI.
- DBCAPI – is a function library that acts as intermediate conversion layer between the PHP extension and the CT-Library.
- CT-Library – is a Sybase Open Client library that you can use to send commands to Adaptive Server, process the results and return the data.
Version Requirements
For information about platform support, see the Software Developers Kit and Open Server Installation Guide for your platform.
- Adaptive Server Enterprise – version 15.7 or later. The PHP driver has been developed and tested against version 15.7. However, the driver can connect to Adaptive Server version earlier than 15.7.
- PHP installation – version 5.3.6.
- CT-Library from Open Client SDK – version 15.7
- DBCAPI — Sybase recommends that you use the DBCAPI library and the PHP driver from the same SDK installation.
