When you mean getting friends' birthdays corresponding to today - I'm assuming you want to find if any of your friends birthday is today or not.

1) First thing, you have to get today's date:

$today = date('m\/d');

2) Second using this date, we will run a query to select all your friends whose birthday is today

$data = $facebook->api(array(
    'method'    =>'fql.query',
    'req_perms' => 'friends_birthday',
    'query'     => "select uid,name,birthday_date from user where uid in (select uid2 from friend where uid1=me()) and strpos(birthday_date,$today)>=0 ") );

3) Next you check the size of the data set, if it's ZERO - there are no birthdays today, else you loop through the dataset and print the friends name whose birthday is today.

if(count($data)==0)
{
   echo 'No Friends Birthdays today';
}
else
{
    echo 'Friends whose birthday is today';
    foreach($data as $today_bday) {
        echo $today_bday['name'];
    }
}
