How to use php to connect to remote oracle in win7

I believe everyone knows Oracle, but not everyone knows how to use PHP to connect to a remote Oracle. Today I will take you through how to use PHP to connect to a remote Oracle. Friends in need can refer to it.

<?php
/*
先下载oracle客户端
下载地址
http://www.oracle.com/technetwork/topics/winx64soft-089540.html
下载如下三个版本
instantclient-basic-win64-10.2.0.5.zip
instantclient-sqlplus-win64-10.2.0.5.zip
instantclient-odbc-win64-10.2.0.5.zip



另下载php Oracle驱动，下载地址 https://windows.php.net/downloads/pecl/releases/oci8/2.0.10/
这里版本是
php_oci8-2.0.10-5.5-ts-vc11-x64.zip
将其中内容全部解压缩到php编译文件目录下的 ext 文件夹里
这里是
D:\ApacheServer\php\ext



将三个压缩包解压缩到一个默认文件夹 instantclient_10_2 下
这里instantclient_10_2 放在了 Navicat Premium 安装目录下，位置为
D:\ApacheServer\Navicat Premium\instantclient_10_2

修改环境变量
全部在系统变量中
修改如下
新增
变量名
NLS_LANG
变量值
SIMPLIFIED CHINESE_CHINA.ZHS16GBK

变量名
ORACLE_HOME
变量值
D:\ApacheServer\Navicat Premium\instantclient_10_2

变量名
TNS_ADMIN
变量值
D:\ApacheServer\Navicat Premium\instantclient_10_2

修改
变量名
Path
结尾处新增
;D:\ApacheServer\Navicat Premium\instantclient_10_2
注意和之前值之间有个 ;










instantclient_10_2 目录下新建 TNSNAME.ORA，这里是D:\ApacheServer\Navicat Premium\instantclient_10_2\TNSNAME.ORA
内容如下
================================以下TNSNAME.ORA内容==============================
SHTSDB =
　　(DESCRIPTION =
　　　　(ADDRESS = (PROTOCOL = TCP)(HOST = 45.97.194.92)(PORT = 1521))
　　　　(CONNECT_DATA =
　　　　(SERVER = DEDICATED)
　　　　(SERVICE_NAME = SHTSDB)
　　)
)

EXTPROC_CONNECTION_DATA =
　　(DESCRIPTION =
　　　　(ADDRESS_LIST =
　　　　(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
　　　　)
　　(CONNECT_DATA =
　　　　(SID = PLSExtProc)
　　　　(PRESENTATION = RO)
　　)
)
================================以上TNSNAME.ORA内容==============================
SHTSDB 是Oracle实例名（库名，SID名），服务器IP 45.97.194.92，端口号1521






启动命令行
d:
cd D:\ApacheServer\Navicat Premium\instantclient_10_2
odbc_install.exe



最后重启电脑




输入如下代码测试即可
新建index.php页面，输入如下内容
*/
phpinfo();exit;
$db_server = "45.97.194.92";
$db_user = "YIMAI";
$db_pass = "YIMAI";
$db_sid = "SHTSDB";
$dbconn=OCILogon($db_user,$db_pass,"(DEscriptION=(ADDRESS=(PROTOCOL=TCP)(HOST=45.97.194.92)(PORT= 1521))(CONNECT_DATA =(SID=$db_sid)))"); 
if($dbconn!=false) 
{
    echo "连接"; 
    echo "DB服务器:".$db_server;
    echo "用户:".$db_user;
    echo "口令:".$db_pass;
    echo "SID:".$db_sid;
    echo "成功\n";
    if(OCILogOff($dbconn)==true) 
    { 
        echo "关闭连接成功!";
    } 
} 
else 
{ 
    echo "连接失败"; 
} 
?>
