Configuration Overview

Environment Variables

To successfully use the extension module, set Sybase environment variables in the environment in which you run the PHP executable. At a minimum, you must set the $SYBASE and $SYBASE_OCS environment variables. Set the LD_LIBRARY_PATH variable to point to the correct location under the $SYBASE/$SYBASE_OCS/lib directory. The extension module loads the DBCAPI library from this location.

Sample Script

A script is provided that creates a sample php.ini file, which allows PHP to locate the extension module from the directory in which it is installed. This script, generate_php_ini.sh, is located in $SYBASE/$SYBASE_OCS/config. You must correctly set $SYBASE and $SYBASE_OCS for the generate_php_ini.sh script to generate the correct php.ini file.

You can use the generated php.ini file to run the firstapp.php sample or any other test using the extension module. For a typical installation, a php.ini file already exists and the information from the generate_php_ini.sh script in the sample php.ini is copied into an existing php.ini file.

A system administrator can copy the extension module into a different extension specific directory and load the extension module from the directory by modifying the php.ini file, for example:

; Set the default extension directory.
extension_dir = "/usr/local/lib/php/extensions" 
;Load the Sybase ASE PHP driver: sybaseasephp extension="sybaseasephp.so"

Once the file is modified, you can copy the $SYBASE/$SYBASE_OCS/php/php536_64/lib/sybaseasephp.so or $SYBASE/$SYBASE_OCS/php/php536_64/devlib/sybaseasephp.so library to /usr/local/lib/php/extensions.

Extension Libraries

When executing php -m you should see the sybaseasephp extension listed among the extensions active in the PHP installation.
