PHP连接Oracle数据库

• 基础环境

1. CentOS 7.2.1511
2. PHP Version 5.6.31
3. Oracle-xe-11g

• 扩展选择

1. Oracle OCI8

• 安装依赖

1. 下载rpm包
   oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
   oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm
2. 安装rpm包

rpm -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
rpm -ivh oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm

• 查看安装结果

[root@d13306817df8 /]$ rpm -qa | grep oracle
oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64
oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64

• 配置instantclient

[root@d13306817df8 /]$ echo '/usr/lib/oracle/11.2/client64/lib/' > /etc/ld.so.conf.d/oracle-x86_64.conf
[root@d13306817df8 /]$ ln -s /usr/lib/oracle/11.2/client64 /usr/lib/oracle/11.2/client  
[root@d13306817df8 /]$ ln -s /usr/include/oracle/11.2/client64 /usr/include/oracle/11.2/client
// vim /etc/profile && . /etc/profile
[root@d13306817df8 /]$ export ORACLE_HOME=/usr/lib/oracle/11.2/client64/  
[root@d13306817df8 /]$ export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64:$LD_LIBRARY_PATH  
[root@d13306817df8 /]$ export NLS_LANG="AMERICAN_AMERICA.AL32UTF8"

• 安装扩展

[root@d13306817df8 /]$ /usr/local/php56/bin/phpize 
[root@d13306817df8 /]$ cd /root/php-5.6.31/ext/oci8/
[root@d13306817df8 /]$ ./configure --with-php-config=/usr/local/php56/bin/php-config --with-oci8=shared,instantclient,/usr/lib/oracle/11.2/client64/lib
[root@d13306817df8 /]$ make
[root@d13306817df8 /]$ make install
[root@d13306817df8 /]$ cd /usr/local/php56/lib/php/extensions/no-debug-non-zts-20131226/
[root@d13306817df8 /]$ ls 
ZendGuardLoader.so  memcache.so  oci8.so  opcache.a  opcache.so  opcache_zend.so  swoole_loader56.so
[root@d13306817df8 /]$  echo 'extension = oci8.so' > /usr/local/php56/etc/php.d/oci8.ini

• 代码使用实例

• 补充说明
  1. Oracle的安装其实是比较烦的，所以我选择使用了Docker
     docker pull alexeiled/docker-oracle-xe-11g
  2. Oracle的表名是大写的，刚才创建的表应该是MASON
     select * from user_tables WHERE TABLE_NAME = 'MASON'
