$sql4="select denglu_time from user where user_name = '$_POST[username]' and password = '$_POST[u_password]'";
$result4 = mysql_query( $sql4);
$row1 = mysql_num_rows($result4);
echo "Time$row1[denglu_time]";
Why can’t the time in the database be output? How can I output the time correctly?

You can try to store the timestamp in the database, and then convert the timestamp into time in PHP when needed
$row1['denglu_time']
The subscript needs to be quoted for a string. If there are no quotes, if there is a constant equal to the index value at this time, the index will be converted to a constant value
