Hey guys,
How would I go about subtracting Today from a previous day to find the difference?

For example, I want to subtract TODAY from a previous date in my database, to determine if the difference is greater than 1 day.

Any ideas? I tried doing the subraction in TIMESTAMPS, but when I convert the date back to Y-m-d H:i:s, I got some weird year and time.
 

At the moment I have:

$month_end_date[$surgeryinvoicescount]=$i[0]; = 2011-04-13

I would like

$month_end_date[$surgeryinvoicescount]=$i[0]; = 13/04/2011

I have tried the following but didn't work?!:

$month_end_date = date('d/m/Y',strtotime($month_end_date));
$month_end_date[$surgeryinvoicescount]=$i[0];

I am trying to display "open" / "closed" depending on the time of day.  I tried to write my own script but it doesn't seem to be working.  Does anyone know of some boxed script I can use?

Here is what I have...



function open(){

$AMPM = date('A', time());
if ($AMPM == "PM"){

connect();

$day = date('l');


$sqlcurrent = "select * from hours where day = '$day' and closed ='1'";
$currently = mysql_query($sqlcurrent) or die(mysql_error());
$checkDay = mysql_num_rows($currently);

if ($checkDay == "1"){
while($getID = mysql_fetch_assoc($currently)){

$convertopen = strtotime($getID['open']);
$convertclose = strtotime($getID['close']);

$displayTimeH = date('H', time());
$displayTimeM = date('i', time());
$displayTimeAMPM = date('A', time());

$opentime = explode(":", $getID['open']);
$openhour=$opentime[0];
$openminute=$opentime[1];

$closetime = explode(":", $getID['close']); 
$closehour=$closetime[0];
$closeminute=$closetime[1];

//echo "$closehour$closeminute<br />";
//echo "$displayTimeH$displayTimeM<br />";


if (($openhour <= $displayTimeH && $openminute <= $displayTimeM) && ($closehour >= $displayTimeH && $closeminute >= $displayTimeM)){
echo "We're Open ... Come On In!";
}else{
echo "Hours of Service";
}


}
}else{
echo "Hours of Service";
free($currently);

}
}else{
echo "Hours of Service";
}
} // close function



I know it's brutal but it's all I could come up with...
