Getting crazy selecting dates on a mysql table (long)

Question

Hi all,
I have a problem that is driving me crazy.
I have a table containing 2 columns (QUOTATION and DATE).
I want to extract only the records that have the date falling
between
a specific range.
I've set 2 variables to hold the two dates:
$start_date=date
("Y-m-d",mktime(0,0,0,date("m"),date("d")-90,date("Y")));
$end_date=date
("Y-m-d",mktime(0,0,0,date("m"),date("d"),date("Y")));
But when I run this query:
SELECT quotation, date FROM mytable WHERE date BETWEEN
{$start_date}
AND {$end_date} ORDER BY date DESC";
I get ... nothing selected.
If I use:
SELECT quotation, date FROM mytable WHERE date >
{$start_date} ORDER
BY date DESC";
I get _all_ records: the records before and after the
$start_date.
Here is my little script:
=====================================
<?php
mysql_select_db($database_mmm_conn, $mmm_conn);
$quotation = (isset($_GET['quotation'])) ?
mysql_real_escape_string($_GET['quotation']) : "";
if ($quotation)
$quotationquery=$metallo;
else {
$quotationquery='default_quotation';
$start_date = (isset($_GET['start_date'])) ?
mysql_real_escape_string($_GET['start_date']) : "";
if ($start_date)
$start_date_query=$start_date;
else {
$start_date_query=date
("Y-m-d",mktime(0,0,0,date("m"),date("d")-90,date("Y")));;
$end_date = (isset($_GET['end_date'])) ?
mysql_real_escape_string($_GET['end_date']) : "";
if ($end_date)
$end_date_query=$end_date;
else {
$end_date_query=date
("Y-m-d",mktime(0,0,0,date("m"),date("d"),date("Y")));;
$query_dati = "SELECT {$quotationquery}, date FROM mytable
WHERE date
BETWEEN {$start_date_query} AND {$end_date_query} ORDER BY
date
DESC";
$dati = mysql_query($query_dati, $mmm_conn) or
die(mysql_error());
$row_dati = mysql_fetch_assoc($dati);
$totalRows_dati = mysql_num_rows($dati);
?>
===============================
the command
<? echo $query_dati; ?>
will return:
SELECT quotation, date FROM mytable WHERE date BETWEEN
2007-09-19 AND
2007-12-18 ORDER BY date DESC
Even in PhpMyAdmin I don't get anything.
Heeelllppppp!!
Any suggestion will be very appreciated.
Ciao ;).

You don't need those complex PHP calculations to find the
start and end
dates. It's much more efficient to do it in your SQL like
this:
$query_dati = "SELECT {$quotationquery}, date FROM mytable
WHERE date
BETWEEN DATE_SUB(NOW(), INTERVAL 3 MONTH) AND NOW() ORDER BY
date
DESC";
