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) {
        $e = oci_error();
        //print htmlentities($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！");
        $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';
        }
        else{
            $arr_result['result']='true';
        }
