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().
Example 1. mysql_num_rows() example |
<?php
$link = mysql_connect("localhost", "mysql_user", "mysql_password");
mysql_select_db("database", $link);
$result = mysql_query("SELECT * FROM table1", $link);
$num_rows = mysql_num_rows($result);
echo "$num_rows Rows\n";
?>

Note:
If you use mysql_unbuffered_query(),
mysql_num_rows() will not return the
correct value until all the rows in the result set have been
retrieved.
See also
mysql_affected_rows(),
mysql_connect(),
mysql_data_seek(),
mysql_select_db() and
mysql_query().
For downward compatibility mysql_numrows() can
also be used. This is deprecated however.
