In addition to normal ODBC support, the Unified ODBC functions in
PHP allow you to access several databases that have borrowed the
semantics of the ODBC API to implement their own API. Instead of
maintaining multiple database drivers that were all nearly
identical, these drivers have been unified into a single set of
ODBC functions.
Замечание:
There is no ODBC involved when connecting to the above
databases. The functions that you use to speak natively to them
just happen to share the same names and syntax as the ODBC
functions. The exception to this is iODBC. Building PHP with iODBC
support enables you to use any ODBC-compliant drivers with your PHP
applications. iODBC is maintained by
OpenLink Software. More information on iODBC, as well as a
HOWTO, is available at www.iodbc.org.
Include Adabas D support. DIR is the Adabas base install directory,
defaults to /usr/local.
--with-sapdb[=DIR]
Include SAP DB support. DIR is SAP DB base install directory,
defaults to /usr/local.
--with-solid[=DIR]
Include Solid support. DIR is the Solid base install directory,
defaults to /usr/local/solid.
--with-ibm-db2[=DIR]
Include IBM DB2 support. DIR is the DB2 base install directory,
defaults to /home/db2inst1/sqllib.
--with-empress[=DIR]
Include Empress support. DIR is the Empress base install directory,
defaults to $EMPRESSPATH. From PHP 4, this option only supports
Empress Version 8.60 and above.
--with-empress-bcs[=DIR]
Include Empress Local Access support. DIR is the Empress base
install directory, defaults to $EMPRESSPATH. From PHP 4,
this option only supports Empress Version 8.60 and above.
--with-birdstep[=DIR]
Include Birdstep support. DIR is the Birdstep base install directory,
defaults to /usr/local/birdstep.
--with-custom-odbc[=DIR]
Include a user defined ODBC support. The DIR is ODBC install base directory,
which defaults to /usr/local. Make sure to define
CUSTOM_ODBC_LIBS and have some odbc.h in your include
dirs. E.g., you should define following for Sybase SQL Anywhere 5.5.00 on
QNX, prior to run configure script:
CPPFLAGS="-DODBC_QNX -DSQLANY_BUG"
LDFLAGS=-lunix
CUSTOM_ODBC_LIBS="-ldblib -lodbc".
--with-iodbc[=DIR]
Include iODBC support. DIR is the iODBC base install directory,
defaults to /usr/local.
--with-esoob[=DIR]
Include Easysoft OOB support. DIR is the OOB base install directory,
defaults to /usr/local/easysoft/oob/client.
--with-unixODBC[=DIR]
Include unixODBC support. DIR is the unixODBC base install directory,
defaults to /usr/local.
--with-openlink[=DIR]
Include OpenLink ODBC support. DIR is the OpenLink base install directory,
defaults to /usr/local. This is the same as iODBC.
--with-dbmaker[=DIR]
Include DBMaker support. DIR is the DBMaker base install directory,
defaults to where the latest version of DBMaker is installed
(such as /home/dbmaker/3.6).
To disable unified ODBC support in PHP 3 add
--disable-unified-odbc to your configure
line. Only applicable if iODBC, Adabas, Solid, Velocis or a custom ODBC
interface is enabled.
