Dates in PHP (Tomorrow, Yesterday, Today of a Given Date)
<?php
echo “<h4>Date Yesterday</h4>”;
$yesterday = date(“Y-m-d”, time()-86400);
echo $yesterday;
echo “<h4>Date Today</h4>”;
echo date(“Y-m-d”);
echo “<h4>Date Tomorrow</h4>”;
$tomorrow = date(“Y-m-d”, time()+86400);
echo $tomorrow;
echo “<hr>”;
echo “<h4>Previous Date from User-defined Date</h4>”;
$gdate = “2008-07-11”;
echo “(” . $gdate . ” supplied.) <br>”;
$dt = strtotime($gdate);
echo date(“Y-m-d”, $dt-86400);
echo “<h4>Next Date from User-defined Date</h4>”;
echo “(” . $gdate . ” supplied.) <br>”;
$dt = strtotime($gdate);
echo date(“Y-m-d”, $dt+86400);
// DAYS IN BETWEEN TWO DATES
function days_in_between($s, $e){
$d = array();
$s = strtotime($s);
$e = strtotime($e);
for($n=$s; $n<=$e; $n=$n+86400){
array_push($d, strftime(“%Y-%m-%d”, $n));
}
return $d;
}
?>

you could also generate the date and time for tomorrow and yesterday by strtotime(“yesterday”); or strtotime(“tomorrow”);
For this you get the time portion for 00:00 o’clock then.
Be careful with just adding 86400 to the current timestamp. On days with a summer-winter-time change you can get false results because of the difference of one hour.

NOPE NOPE NOPE. In your locale you may have run afoul of the daylight savings time change. Adding 86400 is not reliable for adding days!
