同事昨天接到一个任务,要用php处理oracle数据库的内容,但是php打开oracle扩展不是像mysql那样直接用就行,需要下一点东西才能打开
第一步 需要到oracle官方下载一个install client 包,在win下找到你对应系统版本的zip(注意这里是系统版本)
截止到2015-06-25,下载地址如下http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
例如选择 Instant Client for Microsoft Windows (x64) 因为php扩展的是OCI,所以必须选对应版本的最全的那个,别的都没有OCI,这里下载可能需要有个账号,验证以后就可以下载,直接用连接下载不好用,没有的话注册一下就好了
第二部,需要下载win系统中的扩展包也就是.dll文件 下载地址 http://pecl.php.net/package/oci8 下面一段废话是告诉你怎么找的
http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html 在这个地址下点击
official Instant Client site. 拉到最后 Related Developer Centers 里面点 "PHP - OCI8 extension"
然后选项卡 downloads 点OCI8 到 http://pecl.php.net/package/oci8
然后怎么下载就不多说了
到这里完成下载两个zip包,然后就是配置PHP
第三,解压下载的第一个文件,到电脑任意目录,解压后得到文件目录 instantclient_12 _1 建议把后面的 "_12_1"去掉,以后改版本就不用动环境变量了
进入这个目录后双击打开 adrci.exe
得到如下命令行窗口,证明这个客户端在你本地可用
复制目录,我的是 F:\dev\instantclient 配置到系统的path环境变量,
第四,解压下载的dll的压缩包,复制其中的 php_oci8.dll php_oci8_11g.dll php_oci8_12c.dll 我目前就是这三个,到php的扩展包文件,通常是 ....../php/ext/目录下
其实可以不替换,不过建议还是替换一下好,
然后打开php.ini 把扩展打开,最后一个是后来加进去的,php本来没有,反正上面包里有的dll文件都写进去应该错不了,顶多运行php的时候多加载几个库
extension=php_pdo_oci.dll
extension=php_oci8.dll ; Use with Oracle 10gR2 Instant Client
extension=php_oci8_11g.dll ; Use with Oracle 11gR2 Instant Client
extension=php_oci8_12c.dll ; Use with Oracle 12c Instant Client
然后重启httpd服务,打开 phpinfo(); 应该能看到
| PDO support | enabled |
|---|---|
| PDO drivers | mysql, oci, odbc |
| OCI8 Support | enabled |
| OCI8 DTrace Support | disabled |
| OCI8 Version | 2.0.8 |
| Revision | $Id: f04114d4d67cffea4cdc2ed3b7f0229c2caa5016 $ |
| Oracle Run-time Client Library Version | 12.1.0.2.0 |
| Oracle Compile-time Instant Client Version | 10.2 |
这样就说明扩展打开成功了
最后就是连接oracle数据库了
这里给一个实例连接 原文连接 http://www.orczhou.com/index.php/2010/09/php-oci8-oracle/
