How can I count the numbers of rows that a mysql query returned?

To get the length of the return of a mysql result, I am using:

$counter=0;
while($row = mysql_fetch_array($mysqlqueryresult)){
$counter++;
}
echo $counter;

Is there a better way to get the number of rows returned by mysql?

Note – Not allowed to use COUNT in the mysql or any mysql tricks, only php on the mysql output as here. So starting point is a mysql returned thing of $mysqlqueryresult; which itself is the result of a basic SELECT query.

Answer 1

Use mysql_num_rows.

$counter = mysql_num_rows($mysqlqueryresult);

If you’ve updated the table, the number of affected rows is given by mysql_affected_rows.
