It could be done more easly, but this is one way:
$begindate = strreplace($begindate,'/','.');
$enddate = strreplace($enddate,'/','.');
mysql_query("SELECT * FROM MyTable
WHERE dateField BETWEEN '$begindate 00:00:00' AND '$enddate 23:59:59'");
答
should be something like
SELECT *, STR_TO_DATE(datetime,'%d.%m.%Y') as newdatetime
FROM table
WHERE newdatetime >= STR_TO_DATE('11/12/1999','%d/%m/%Y')
AND newdatetime <= STR_TO_DATE('11/12/2001','%d/%m/%Y');
