php 连接oracle数据库语句怎么写?

php 连接oracle数据库语句怎么写?

Answer 1

以系统为windowns为例，
1、先PHP.INI中的oracle扩展也开启了
PHP下php.ini(注意，有时是在windows目录)修改下下
其中的
extension=php_oci8.dll 去掉前面的“;”号
extension=php_oracle.dll 去掉前面的“;”号

把php_oci8.dll 、和php_oracle.dll 文件复制到windwos的system32下
2、系统中应当有安装ORCALE的系统，然后配制远程ORACLE的的监听。就是你能用你配好的ORACLE系统访问远程的数据库。
{例：
在ORACLE安装目录下找到tnsnames.ora，然后按下面的例子配置一下
BASETEST 命名=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = XX.XX.XX.XX服务器IP地址)(PORT = 1521端口))
)
(CONNECT_DATA = (SERVICE_NAME = masprod 实例ID))
)
}
3.在你的PHP网页目录下写个测试连接的程序试试
<?php
$dbconn=OCILogon("username","pwd","(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = [远程服务器IP])(PORT = 1515))
)
(CONNECT_DATA =
(SERVICE_NAME = [数据库名字])
))");
if($dbconn!=false)
{
echo "连接成功";
if(OCILogOff($dbconn)==true)
{
echo "关闭连接成功!";//=这里有问题
}
}
else
{
echo "连接失败";
}
?>

追问

Call to undefined function ocilogon()是怎么回事
