[PHP] randomly select a table, better way?

[Daniel Bray]

Ok, I have looked through the archives on both MySQL and PHP's lists, but
I have not seen this asked or mentioned.  Weird, I thought this would be a
common thing.  Is there a better way to randomly select a table from a
database, than what I have come up with:

<?php
        srand ((float) microtime() * 10000000);
        $table_array = array ();
        mysql_connect("localhost", "mysql_user", "mysql_password");
        $result = mysql_list_tables("database_name");

        for ($i = 0; $i < mysql_num_rows($result); $i++)
        {
                $table_name = mysql_tablename($result, $i);
                array_push ($table_array , "$table_name");
        }
        
        $rand_keys = array_rand ($table_array, 2);
        echo "<br><br>Here is a random table: <b>" . 
$table_array[$rand_keys[0]]."</b><br>\n";
        
        mysql_free_result($result);
?>

thanks, 
DB
