PHP filter data from MS Access 2003 Database

I am a new one,I am using php 5.2 with MS access Database.
i want to filter records from a table on the base of date.The date format in Database table is “25/05/2009”.
My SQl Query is:
$Sdate=“05/25/2009”; //date format is m/d/Y
“SELECT * from tbl where Start_Date=”. $Sdate ;
When i runs application it s returns no records but when i run same query in MS access Query analyser,it returns data.
i think there is some date format problem.please guide me.
Thanks

did you try with explode() and re-forming the required date?

“SELECT * from tbl where Start_Date=#”. $Sdate .“#” ;
