<?php
//读取mdb数据库例程
$conn = new com("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("./SpiderResult.mdb");

$conn->Open($connstr);
$rs = new com("ADODB.RecordSet");
$rs->Open("select * from Content",$conn,1,1);
while(! $rs->eof)
{
echo $rs->Fields(1)->value;
echo "<br>";
echo $rs->Fields(2)->value;
echo "<br>";
echo $rs->Fields(3)->value;
echo "<br>";
echo "<hr>";
$rs->MoveNext();
}

<?php //读取mdb数据库例程
$conn = new com("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("../mydata.mdb");

$conn->Open($connstr);
$rs = new com("ADODB.RecordSet");
$rs->Open("select * from userinfo",$conn,1,1);
while(! $rs->eof) {
$f = $rs->Fields(1);
echo $f->value;
echo " 　". $rs->Fields(2)->value;
$rs->MoveNext();
}
?>

PHP一般数据写入方法：

<?php
$connstr="DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . realpath("../chen416/mydata.mdb");
$connid=odbc_connect($connstr,"","",SQL_CUR_USE_ODBC);
$issuetime=date("Y-m-d H:i:s");
$sql="insert into userinfo (username,userword,email) values('u2','w2','uw@163.com')";
$result=odbc_exec($connid,$sql);
if($result) echo "successful";
else echo "failed";
?>

3、PHP一般数据读取方法：

<?php //读取mdb数据库例程
$conn=new COM("ADODB.Connection");

$dsn="DRIVER={Microsoft Access Driver (*.mdb)};DBQ=".realpath("../mydata.mdb").";";
//Uid=Admin; Pwd=BDC2002Data;

$conn->open($dsn);

$sql="select * from userinfo";

$rs=$conn->Execute($sql);

$row="0";

while(!$rs->EOF)

{
$string ="";
for ($i=0;$i<$rs->Fields->count;$i++)

{

if ($i==0)

{

$string.=$rs->Fields($i)->Value;

continue;

}

$string.='|'.$rs->Fields($i)->Value;

}

$string.="\n";

if ($row==300)

{

break;

}

$row++;

echo "<br>";
echo $string;
$rs->MoveNext();

}

4、PHP删除数据方法：

<?php
$conn = new com("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("../mydata.mdb");

$conn->Open($connstr);

$query = "delete from userinfo where uid=1";
$result =$conn->Execute($query);

if($result)
echo "删除成功";
else
echo "删除失败";

?>

5、PHP更新数据方法：

<?php
$conn = new com("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("../mydata.mdb");

$conn->Open($connstr);

$query = "update userinfo set username='ganjun' where uid=2";
$result =$conn->Execute($query);

if($result)
echo "更新数据成功";
else
echo "更新数据失败";

?>
