问题 In reference to Check if no result found in mysql db It was previously thought that you could check to see if there as a record set returned by doing the following; $result= mysqli_query($conn,$sql); $rowCount = mysqli_num_rows($result); In the question about this was the accepted solution.

问题 Here is the code I'm using to pull the data from the table: require_once 'connect.php'; $sql = "SELECT * FROM `db-news`"; $result = $mysqli->query($sql); $row = mysqli_fetch_assoc($result); while ($row = $result->fetch_assoc()) { printf ($row['pagename'].' - To edit this page <a href="editnews.php?id='.$row['id'].'">click here</a><br>'); } Always the first row is ignored. I'm not calling mysqli_fetch_assoc twice as with some other examples on SO. I've tried changing echo to printf in the

I have read some people say never to
