prepare("select * from test");
$stmt->execute();
//$myrow = mysql_fetch_row($stmt->execute());
$res=$stmt->fetch();
$myrow = mysql_fetch_row($res);
print_r($myrow);
?>
我加上了 $myrow = mysql_fetch_row($res);这一句想获取一行数据 为什么获取不到一行 提示这个 ( ! ) Warning: mysql_fetch_row() expects parameter 1 to be resource, array given in D:\wamp\www\chaxun.php on line 7
prepare("select * from test");
$stmt->execute();
//$myrow = mysql_fetch_row($stmt->execute());
$res=$stmt->fetch();
$myrow = mysql_fetch_row($res);
print_r($myrow);
?>
PDOStatement::rowCount — 返回受上一个 SQL 语句影响的行数
PDOStatement::fetch — 从结果集中获取下一行
query('SELECT * from users');
//获取一行
$result=$query->fetch();
print_r($result);
$total = $pdo->query('SELECT * from test');
//统计条数
$count=$total->rowCount();
echo $count;
要用while循环取吧
