I need help if PHP operators

[OCCoder]

I am trying to display a message on my webpage that should be triggered by a date check. The code is below (I removed all HTML tags for simplicity for now):

$m=date("m");
$d=date("d");
$y=date("Y");

$int_d = (int)$d;

//Thanksgiving

if ($m="11"&&$y="2010"&&$int_d>23&&$int_d<=28)
	{
	echo 'Happy Thanksgiving!';
	}

//Holidays

if ($m="12"&&$y="2010"&&$int_d>=18&&$int_d<=31)
	{
	echo 'Happy Holidays!';
	}

I want each statement to be executed during the appropriate dates i.e. "Happy Thanksgiving" from 11/24/2010 to 11/28/2010, and "Happy Holidays" from 12/18/2010 to 12/31/2010.

The problem is that both statement are being executed regardless of the date?

Thoughts?

Thanks

if ($m="11" && $y="2010

Look at this test very carefully and think about assignment and comparison operators.
