php访问远程Oracle服务器是否需安装Oracle客户端?
php访问远程Oracle数据库服务器时,php所在服务器是否需要安装Oracle客户端?
------解决方案--------------------
你的php所在的服务器上是要装客户端的。如在linux下，必须和客户端软件一起编译。如在win32下，除了装客户端外，还要做些简单的配置。
------解决方案--------------------
必须有 oracle client.
------解决方案--------------------
要，不然你如何安装好Oracle扩展
------解决方案--------------------
手册上写的很明白把
http://cn.php.net/manual/zh/ref.oci8.php
需求
使用本扩展需要 Oracle 客户端库。Windows 用户需要至少版本号为 10 的库才能使用 php_oci8.dll。
安装所有所需文件最方便的方法是使用 Oracle Instant Client，可以从此处得到：http://www.oracle.com/technology/tech/oci/instantclient/instantclient.html。要使 OCI8 模块能工作， "basic " 版的 Oracle Instant Client 已经足够。Instant Client 不需要 ORACLE_SID 或 ORACLE_HOME 环境变量被设定。不过可能还是要设定 LD_LIBRARY_PATH 和 NLS_LANG。
在使用本扩展之前，请确认已经为 Oracle 用户和 web daemon 用户正确设置了 Oracle 环境变量。这些变量应该在启动 web server 之前设定。下面列出了需要设置的环境变量：
ORACLE_HOME
ORACLE_SID
LD_PRELOAD
LD_LIBRARY_PATH
NLS_LANG
对于较少用到的 Oracle 环境变量例如 TNS_ADMIN，TWO_TASK，ORA_TZFILE 和各种 Oracle 全球性设定例如 ORA_NLS33，ORA_NLS10 和 NLS_* 等变量请参考 Oracle 稳当。
在为 web 服务器用户设置环境变量之后，还需要将 web 服务器用户（nobody，www）加到 oracle 组中。
