PHP下的Oracle客户端扩展(OCI8)安装教程
最近的项目需要用php访问oracle数据库，不得不在linux下给php安装oci8扩展。php也可以使用pdo访问oracle数据库，但还是需要安装客户端。
首先到oracle官网的这个页面下载相关的文件，注意要连数据库服务器的版本，一定要对应，否则安装成功也会连不上，同时也要区分32位、64位服务器，比如我要连的数据库服务器是oracle10.2.0.4，64位主机，那么我要下载下面三个文件：
oracle-instantclient-basic-10.2.0.4-1.x86_64.rpm oracle-instantclient-devel-10.2.0.4-1.x86_64.rpm oracle-instantclient-sqlplus-10.2.0.4-1.x86_64.rpm
1.用以下命令安装
#rpm-ivhoracle-instantclient-basic-10.2.0.4-1.x86_64.rpmoracle-instantclient-devel-10.2.0.4-1.x86_64.rpm oracle-instantclient-sqlplus-10.2.0.4-1.x86_64.rpm
2.安装OCI8PHP扩展
#yuminstalllibaio #cd~ #wgethttp://pecl.php.net/get/oci8-1.3.5.tgz
3.然后执行命令
