php连接oracle数据库的方法

1.在php.ini中打开extension=php_oci8扩展，重启服务。

2.将php/ext目录下的php_oci8.dll文件拷贝到system32目录下

3.安装 Oracle9i客户端精简版 后重启电脑

配置：

$config = array (

    \'dbconfig\' => 
          array (
            \'db_host_name\' => \'192.168.2.197/orcl\',
            \'db_user_name\' => \'zbkf\',
            \'db_password\' => \'zbkf\',
             
          ),
);

查询：    

 

    //返回值  
    $arr_result = array(); 
    $arr_result[\'result\'] = \'false\';  //true false 为黑名单
    $arr_result[\'callerid\'] = $callerid;  
     
    //取数据库参数
    $db_host_name=$config[\'dbconfig\'][\'db_host_name\']; //\'localhost/ORCL\'\'
    $db_user_name=$config[\'dbconfig\'][\'db_user_name\'];//\'asgr\'
    $db_pwd=$config[\'dbconfig\'][\'db_password\']; //\'asgr\'

    //连接Oracle
    $conn = oci_connect($db_user_name,$db_pwd,$db_host_name);//oci_connect(\'asgr\',\'asgr\',\'localhost/ORCL\');
    if (!$conn) { 
        $e = oci_error(); 
        //print htmlentities($e[\'message\']); 
        //WriteLog("连接Oracle时出错,oci_connect(".$db_user_name.",".$db_pwd.",".$db_host_name.")  ".htmlentities($e[\'message\']));
        $arr_result[\'result\'] = \'false\';
        echo json_encode($arr_result);  //默认为不是黑名单
        return;
    } 
    else {
        //echo("连接成功！");
        //$select = \'SELECT BL_TEL FROM CC_BLACKLIST\'; // 查询语句 
        $select = "Select count(BL_Tel) from CC_BlackList where BL_Tel like \'%" . $callerid . "%\' and BL_SFQY=\'0\' ";
        //WriteLog($select);
        $result_rows = oci_parse($conn, $select); // 配置SQL语句，执行SQL
        $row_count = oci_execute($result_rows, OCI_DEFAULT); // 行数  OCI_DEFAULT表示不要自动commit 
        //echo($row_count);
        if(!$row_count) { //没有行
            $e = oci_error($result_rows); 
            //echo htmlentities($e[\'message\']); 
            //WriteLog("查询时出错或没有行！,oci_connect(".$db_user_name.",".$db_pwd.",".$db_host_name.")  ". $select."  ".htmlentities($e[\'message\']));
            $arr_result[\'result\'] = \'false\';
            echo json_encode($arr_result);  //默认为不是黑名单
        } 
        /*
        //取每行每列值 
        while($row = oci_fetch_array($result_rows, OCI_RETURN_NULLS)) {
             if($row[0]==$callerid){
                $arr_result[\'result\']=\'true\';
                echo json_encode($arr_result);  //是黑名单
                exit;
             }
        }
        */
        $count=0;
        while($row = oci_fetch_array($result_rows, OCI_RETURN_NULLS)) {
            $count=$row[0];
            break;
        }
        //WriteLog($count);
        if($count>=1){
            $arr_result[\'result\']=\'true\';
        }
        else {
            $arr_result[\'result\']=\'false\';
        }
        echo json_encode($arr_result);  //默认为不是黑名单
    }

 

插入：

    //连接Oracle
    $conn = oci_connect($db_user_name,$db_pwd,$db_host_name);//oci_connect(\'asgr\',\'asgr\',\'localhost/ORCL\');
    if (!$conn) {

        $arr_result[\'result\'] = \'false\';
        echo json_encode($arr_result);  //默认为不是黑名单
        return;
    } 
    else {
        //echo("连接成功！");
        $sql = "insert into CC_LEAVEMESSAGE (ID,MESSAGEID,CALLINGNBR,LEAVEMESSAGETIME,FILENAME)  values (sys_guid(),\'" . $SessionId . "\',\'"  . $CallerId . "\',sysdate,\'" . $RecordFile . "\')";
        //WriteLog($sql);
        $stid = oci_parse($conn, $sql); // 编译SQL语句，准备执行 
        $r = oci_execute($stid); // 执行SQL

        oci_free_statement($stid); 
        oci_close($con); //关闭连接
        //WriteLog($r);
        if(!$r) { 
            $e = oci_error($sql); 
            WriteLog("留言写入Oracle时出错,oci_connect(".$db_user_name.",".$db_pwd.",".$db_host_name.") " .$sql . \'  \'  .htmlentities($e[\'message\']));
            $arr_result[\'result\']=\'false\';
        }
