那个，初来乍到，想问问有没有大佬帮忙瞅瞅这个，pdo代码看上去是正确的，但是没办法运行，有没有事那地帮忙指点一下，麻烦了！<?php $dbms='mysql'; $user='root'; $pwd=''; $dbName='san'; $host="localhost"; $dsn = "$dbms:host=$host;dbname=$dbName"; try { $pdo= new PDO($dsn,$user,$pwd); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ATTR_ERRMODE_WARNING); $query-"select*from tb_pdo_mysqls"; $result=$pdo->prepare($query); $result->execute(); while ($res=$result->fetch(PDO::ATTR_FETCH_ASSOC)){ ?> <tr> <td height="22" align="center" valign="middle"><?php echo $res['id'];?></td> <td align="center" valign="middle"><?php echo $res["pdo_type"];?></td> <td align="center" valign="middle"><?php echo $res["database_name"];?></td> <td align="center" valign="middle"><?php echo $res["dates"];?></td> </tr> <?php } }catch (PDOException $e){ "Error!: " . $e->getMessage() . "<br/>"; die(); } ?>
