HomeBackend DevelopmentPHP TutorialWAMP环境中扩展oracle函数库(oci)_PHP

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/

<&#63;php 
//配置信息
$ora_host = "172.16.1.150";
$ora_port="1521";
$ora_sid = "cop";
$ora_username = "webdev";
$ora_password = "webdev";
$charset = "UTF8"; ### zhs16gbk ###

//构建Easy Connect string
//(如果tnsnames.ora中已经有了,可以直接使用Connect Name)
$ora_connstr = "(description=(address=(protocol=tcp)
(host=".$ora_host.")(port=".$ora_port."))
(connect_data=(service_name=".$ora_sid.")))";
//连接数据库
$conn = oci_connect($ora_username, $ora_password,$ora_connstr);
//执行Query,这里$res接收的是一个boolean值
$stid = oci_parse($conn, 'select * FROM dq_try_app');
$res = oci_execute($stid);

//在while循环中使用oci_fetch_array遍历结果。
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
  
  foreach ($row as $item) {
    echo $item."***";
  }
  echo "<br>";
  
}
//var_dump($stid);  
&#63;>

至此,整个的扩展加连接就完成了
