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. Alternatives to this function include:

- mysqli_num_rows()
- mysqli_stmt_num_rows()
- PDOStatement::rowCount()

### 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()
