mysql_num_rows — Get number of rows in result

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

Description

mysql_num_rows ( resource $result ) : int|false

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 to mysql_query().

Return Values

The number of rows in a result set on success or FALSE on failure.

Examples

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";?>

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()
