WAMP环境中扩展oracle函数库(oci)
本文给大家介绍的是在windows环境下为php环境扩展Oracle函数库的过程，十分的详细，有需要的小伙伴可以参考下。
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
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 下面一段废话是告诉你怎么找的
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
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
"; } //var_dump($stid); ?>
至此,整个的扩展加连接就完成了
以上所述就是本文的全部内容了，，希望大家能够喜欢。

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_
How to encrypt oracle view
Apr 11, 2025 pm 08:30 PM
Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

How to create a table in oracle
Apr 11, 2025 pm 08:00 PM
Creating an Oracle table involves the following steps: Use the CREATE TABLE syntax to specify table names, column names, data types, constraints, and default values. The table name should be concise and descriptive, and should not exceed 30 characters. The column name should be descriptive, and the data type specifies the data type stored in the column. The NOT NULL constraint ensures that null values are not allowed in the column, and the DEFAULT clause specifies the default values for the column. PRIMARY KEY Constraints to identify the unique record of the table. FOREIGN KEY constraint specifies that the column in the table refers to the primary key in another table. See the creation of the sample table students, which contains primary keys, unique constraints, and default values.

How to read the oracle awr report
Apr 11, 2025 pm 09:45 PM
An AWR report is a report that displays database performance and activity snapshots. The interpretation steps include: identifying the date and time of the activity snapshot. View an overview of activities and resource consumption. Analyze session activities to find session types, resource consumption, and waiting events. Find potential performance bottlenecks such as slow SQL statements, resource contention, and I/O issues. View waiting events, identify and resolve them for performance. Analyze latch and memory usage patterns to identify memory issues that are causing performance issues.
