Summary: Access数据库操作类

*************************************

使用范例：

========================

$databasepath='D:/wwwroot/cef/www/class/testdb.mdb';

//或者$databasepath='testdb.mdb';

$dbusername='';

$dbpassword='';

require_once('cls_access.php');

$access=new Access($databasepath,$dbusername,$dbpassword);

print_r($access->getlist("SELECT TOP 5 * FROM `Result` WHERE `ResultNo` < 12 ORDER BY `ResultNo` DESC"));

echo $access->num_rows("update `conner` set `connerip` = '222.35.142.101' where `connerno` < 83");

========================

*/



class Access{

    var $databasepath,$constr,$dbusername,$dbpassword,$link;

    function Access($databasepath,$dbusername,$dbpassword){

        $this->databasepath=$databasepath;

        $this->username=$dbusername;

        $this->password=$dbpassword;

        $this->connect();

    }

function connect(){

    $this->constr='DRIVER={Microsoft Access Driver (*.mdb)};DBQ='.realpath($this->databasepath).';';

    $this->link=odbc_connect($this->constr,$this->username,$this->password,SQL_CUR_USE_ODBC);

    if(!$this->link) echo "数据库连接失败!";

    return $this->link;

}



function query($sql){     //直接运行SQL，可用于更新、删除数据

    return @odbc_exec($this->link,$sql);

}



function fetch_array($query){     //取得当前指针处记录

    return odbc_fetch_array($query);

}



function fetch_row($query){    //基本同fetch_array(),但只有数字索引

    return odbc_fetch_row($query);

}



function num_rows($sql){    //返回SQL查询影响到的行的数目

    return odbc_num_rows($this->query($sql));

}



function close(){    //关闭数据库连接函数

    odbc_close($this->link);

}



function getlist($sql){    //取得记录列表

    $query=$this->query($sql);

    $recordlist=array();

    while ($row=$this->fetch_array($query)){

        $recordlist[]=$row;

    }

    return $recordlist;

}

}

这个类用的是ODBC，并不想网上说的要用ODBC数据源。我直接新建一个*.mdb文件就可以使用。

再附上部分常用COM方式操作Access代码：

$db = $_SERVER['DOCUMENT_ROOT'].'/zhuanti/ugdkfjlsg54356k6546jk654gfslkg6544s.mdb';

$conn = new COM('ADODB.Connection') or die('can not start Active X Data Objects');

$conn->Open("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$db");

JS调用页js.php

include_once('conn.php');

$rs = $conn->Execute("SELECT TOP 3 * FROM userstar where chk = 1 ORDER BY id DESC");

$idgb=1;

while(!$rs->EOF){

    $gbinf[$idgb]['id'] = $rs->Fields['id']->Value;

    $gbinf[$idgb]['usname'] = $rs->Fields['usname']->Value;

    $gbinf[$idgb]['usage'] = $rs->Fields['usage']->Value;

    $gbinf[$idgb]['usprovince'] = $rs->Fields['usprovince']->Value;

    $gbinf[$idgb]['usfile'] = $rs->Fields['usfile']->Value;

    $gbinf[$idgb]['thumb'] = $rs->Fields['thumb']->Value;

    $gbinf[$idgb]['usmessage'] = $rs->Fields['usmessage']->Value;

    $rs->MoveNext();

    $idgb++;

}

$rs->Close();

$rs = null;

$uhtml='';

$uhtml.='';

for ($i=1; $i<4; $i++){

    $uhtml.='';

}

$uhtml.='
';

    if ($gbinf[$i]['usfile']){

        $uhtml.='
'.$gbinf[$i]['usprovince'].' '.$gbinf[$i]['usname'];

        if ($gbinf[$i]['usage'] != 0){

            $uhtml.=' ('.$gbinf[$i]['usage'].'岁)
';

        }

       $uhtml.=''.$gbinf[$i]['usmessage'].'';

    }

    $uhtml.='
';

echo "document.write('".$uhtml."')";

又一段代码例子，以本文件路径确定数据库路径：

/*

===========================

数据库连接配置

*/

$db = getcwd().'\images\90d\90dicr_os6546oftff_ic543e_cces_4535s.mdb';

$conn = new COM('ADODB.Connection') or die('can not start Active X Data Objects');

$conn->Open("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$db");

/*

===========================

*/

//print_r($_POST);

if ($_POST['name'] && $_POST['tel'] && $_POST['addr'] && $_POST['email'] && $_POST['goal'] && $_POST['high'] && $_POST['weight'] && $_POST['message'])

{

$addsql = "INSERT INTO d90usr (`name`, `tel`, `addr`, `email`, `goal`, `high`, `weight`, `message`) VALUES ('".$_POST['name']."', '".$_POST['tel']."', '".$_POST['addr']."', '".$_POST['email']."', '".$_POST['goal']."', '".$_POST['high']."', '".$_POST['weight']."', '".strip_tags($_POST['message'])."')";

//echo '
'.$addsql;

$rsadd = $conn->Execute($addsql);

echo '';
