Programming skills and logic.
Perhaps you could check that the returned elements contain some viable
data after checking if they're set, and if they don't contain such
expected viable data, then you could output something else?
Given:
$cov = mysql_fetch_row($result);
Then:
if ( isset( $cov[0], $cov[1] ) && is_string( $cov[0] ) && is_string( $cov
[1] ) && strlen( $cov[0] ) > 4 && strlen( $cov[1] ) > 4 ) {
// here you use $cov[0] and $cov[1] in the output
} else {
// here you have an alternative output
}
Now please note carefully:
The order of multiple tests in an if statement as shown above can be
critical to prevent errors. Don't change it around!
