If you would like to just find out how many rows are returned by a query without actually using the results, then it's much more efficient to use SQL count function (specially for large tables with millions of rows).


= "SELECT COUNT(indexed-field) AS cnt FROM some-table";
$r = mysql_query($sql);
$row = mysql_fetch_object($r);
