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='';
$uhtml.='
| ';
if ($gbinf[$i]['usfile']){ $uhtml.=' if ($gbinf[$i]['usage'] != 0){ $uhtml.=' ('.$gbinf[$i]['usage'].'岁) } $uhtml.=' ';} $uhtml.=' | ';
echo "document.write('".$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 '';
echo '
恭喜您报名成功，请等待工作人员与您联系！
';echo '
';}
