我已经安装$studid = $_GET['stud_id'];
$classcode = $_GET['class'];
$conn = new MySQLi($host, $username, $password, $dbname) or die('Can not connect to database');
$sql = "SELECT * FROM tbl_students WHERE stud_id = '$studid';";
$sql.= "SELECT * FROM tbl_classes WHERE class_code = '$classcode'";
if ($conn->multi_query($sql)) {
do {
/* store first result set */
if ($result = mysqli_store_result($conn)) {
while ($row = mysqli_fetch_row($result)) {
$studname = $row[3].", ".$row[1];
}
mysqli_free_result($result);
}
/* print divider */
if (mysqli_more_results($conn)) {
printf("-----------------\n");
$studname = $row['fname'];
}
} while (mysqli_more_results($conn));
}else{ echo "error";}
$conn->close();
，当我试图通过XAMPP打开mysql时，我收到以下错误：
ERROR 2002（HY000）：无法通过套接字连接到本地MySQL服务器 ＆＃39; /var/run/mysqld/mysqld.sock' （2）。
