Counting how many MySQL fields in a row are filled (or empty)

Question

I need to put together a method that would allow me to quantify how many fields in a row have been filled by a user.

For example:

User    Name    Age             


        

Answer 1

$result = mysql_query('SELECT * FROM `MyTable`');
while($row = mysql_fetch_row($result)){
    $empty_count = 0;
    $count = count($row);
    for($i = 0; $i < $count; $i++)
        if($row[$i] === '' || $row[$i] === 'NULL')
            $empty_count++;
    echo 'User '.$row[0].' = '.((int)(100*(1-$empty_count/($count-1)))).'% complete';
}
