PHP读取access 数据库的部分方法实例[转]

PHP读取access 数据库的部分方法实例[转], 做个笔记

<?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";
?>
