mysql_num_rows -- Get number of rows in result

Description

int mysql_num_rows ( resource result)

mysql_num_rows() returns the number of rows in a result set. This command is only valid for SELECT statements. To retrieve the number of rows affected by a INSERT, UPDATE or DELETE query, use mysql_affected_rows().

Příklad 1. mysql_num_rows() example

<?php

$link = mysql_connect("localhost", "username", "password");
mysql_select_db("database", $link);

$result = mysql_query("SELECT * FROM table1", $link);
$num_rows = mysql_num_rows($result);

echo "$num_rows Rows\n";

?>

See also: mysql_affected_rows(), mysql_connect(), mysql_select_db(), and mysql_query().

For downward compatibility mysql_numrows() can also be used. This is deprecated however.
