Need one header per category from an array

I am pulling membership listings from a database for a 3 month interval. Below is code to put the month as the header of each entry. I need to put the month as the header of each SECTION of entries for that month. Can someone help please?

$sql = "SELECT id, first_name, last_name, company, date_format(entry_date, '%m-%d-%Y') as formatted_date, date_format(entry_date, '%M') as formatted_month FROM {$mbsp_tablename} WHERE entry_date BETWEEN DATE_SUB( CURDATE( ) ,INTERVAL 2 MONTH ) AND CURDATE( ) ORDER BY entry_date, last_name";
							
$result2 = mysql_query($sql) or die(mysql_error()." - error: could not connect");
							
while ($data = mysql_fetch_array($result2)) {
	echo "<span class='months'>".$data['formatted_month']."</span>";
	echo "<p class='newbies'><strong>".$data['first_name']." ".$data['last_name']."</strong><br />".$data['company']."</p>";
}

Code (markup):

Thanks!

Here is the way I do group printing.

Because you order the results by date, it should be shown fine (only once per section).

$month = '';
while ($data = mysql_fetch_array($result2)) {
    if ($month != $data['formatted_month'])
    {
        $month = $data['formatted_month'];
        echo "<span class='months'>".$data['formatted_month']."</span>";
    }
    echo "<p class='newbies'><strong>".$data['first_name']." ".$data['last_name'
]."</strong><br />".$data['company']."</p>";
}
