Function which simply returns numeric specification what day of week was(or will be) at given date
(same schema as date("w")). Works both for future and past dates. Counting starts from 0
for Sunday and ends at 7 for Saturday. Hope it will help anybody. ;)
Here's the function:
function return_day_of_week($date){
$sy=substr($date, 0, 4);
$sm=substr($date, 5, 2);
$sd=substr($date, 8, 2);
$date_utc=mktime(0,0,0,$sm, $sd, $sy);
$today_utc=mktime(0,0,0,date("m"), date("d"), date("Y"));
if($date_utc>$today_utc){
$future_date=1;
$temp=$date_utc;
$date_utc=$today_utc;
$today_utc=$temp;
}
$utc_difference=$today_utc-$date_utc;
$weeks_count=($utc_difference)/604800;
if($weeks_count<10)
$weeks_count=substr($weeks_count, 0, 1);
else if($weeks_count<100)
$weeks_count=substr($weeks_count, 0, 2);
else if($weeks_count<1000)
$weeks_count=substr($weeks_count, 0, 3);
$days_rest_count=substr(($utc_difference-$weeks_count*604800)/86400, 0, 1);
$was_day_of_week=date("w")-$days_rest_count;
if($was_day_of_week < 0){
if($future_date==1)
$was_day_of_week=0-$was_day_of_week;
else
$was_day_of_week+=7;
}
return $was_day_of_week;
}
