mysql_num_rows — Get number of rows in result

Description

Retrieves the number of rows from a result set. This command is only valid for statements like SELECT or SHOW that return an actual result set. To retrieve the number of rows affected by a INSERT, UPDATE, REPLACE or DELETE query, use mysql_affected_rows().

Parameters

result

The result resource that is being evaluated. This result comes from a call tomysql_query().

Return Values

The number of rows in a result set on success or [false](reserved.constants.php#constant.false) on failure.

Examples

Example #1 mysql_num_rows() example

`<?php

$link

= mysql_connect("localhost", "mysql_user", "mysql_password");
mysql_select_db("database", link);link);link);result = mysql_query("SELECT * FROM table1", $link); numrows=mysqlnumrows(num_rows = mysql_num_rows(numr​ows=mysqln​umr​ows(result);

echo

"$num_rows Rows\n";?>`

Notes

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.

Note:

For backward compatibility, the following deprecated alias may be used: mysql_numrows()
