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).



<?php



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

$r = mysql_query($sql);

$row = mysql_fetch_object($r);

echo $row->cnt;

?>
