Question

$query = "SELECT * FROM XXXX";
$result = mysql_query($query);
$noOfRows = mysql_num_rows($result);

How to check if $result is empty before getting the result of mysql_num_rows?

Answer 1

You can check the $result with a ternary operator and set $noOfRows to 0 if it is false:

$query = "SELECT * FROM XXXX";
$result = mysql_query($query);
$noOfRows = (false===$result)? 0 : mysql_num_rows($result);
