mysql_num_rows
(PHP 4, PHP 5)
mysql_num_rows — Get number of rows in result
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:
Description

Parameters
-

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()
