A pity there seems no way of getting the CURRENT row number that's under iteration in a typical loop, such as: while ($row = mysql_fetch_assoc($result)) { } After all there is an array of row arrays, as signified by mysql_num_rows($result): Say this gives "40 rows" : it would be useful to know when the iteration is on row 39. The nearest seems to be "data seek":but it connects directly to a row number eg (from mysql_data_seek page) for ($i = mysql_num_rows($result) - 1; $i >= 0; $i--) { if (!mysql_data_seek($result, $i)) { echo "Cannot seek to row $i: " . mysql_error() . "\n"; continue; } = it still wouldn't solve knowing what row number you're on in an ordinary loop. One reason for this situation is the php fetch (fetch-a-single-row) construction, without any reasonable FOR loop possibility with row numbers. Suggestion: $Rows[$i] possibility where $i would be the row number $Rows[$row[], $row[], $row[].....] 0 1 2 etc -- the excellent retrieval WITHIN a row ( $row[$i] ), while certainly more important, is not matched by similar possibilities for rows themselves. and Count($result) doesnt work of course, $result being a mere ticket-identifier...
