Convert date

Sorry for asking you all for a thing that simple, but I just can figure it out.

I use in my database the timestamp for date, but how can I convert lets say the day 2007-09-01 to timestamp so I can sore it to the database??

You have me a bit lost... Can you throw us a bit of code so we can see what your are trying to do?

I ussually get the date by using the function date().

$store_database=date('U');

It is then stored in the format:
"Seconds since the Unix Epoch "

That will give me the date of today, but I want sometimes to have the date in this format of example 2009-09-09.

I can't just write:
$store_database=date('2009-09-09');

........how to do it?

$store_database=date('U');
$formDate = gmdate("Y-m-d", strtotime($store_database));

Seems like I'm really stupid, but I looked in manual at gmdate and I don't get it.

todays date (2003-09-13) will be stored in

$today_date=date('U');

Then I want a future date ( a string ) to be converted to the same format. How to do that?

$today_date=date('U');
$date_in_string='2006-09-12';
$future_date= ? ? ? ? ? ?

Please one again....I didn't understand the last post.

Anybody ..... out there ??
