Is it possible to use DateTime to grab every date from now till one week ago and than make an array, for example
1-4-2014
1-3-2014
1-2-2014
And so on
Currently this is my code
<?php
$datetime = new DateTime();
$datetime->format('Y-m-d');
$arr = array(/* diverse dates */);
foreach ($to_remove as $item)
{
$is_smaller = ($to_remove->format('U') <= $datetime->format('U'));
if ($is_smaller)
{
$arr = array_filter($arr, function($item) use ($to_remove) {
return !preg_match("/$to_remove by /", $item);
});
}
}
Basically I need it to check the current date and the dates from one week ago and then remove the string from the array.

Answer 1

Yes, you can use DateTime class and DateInterval with DatePeriod:
$now = new DateTime( "now");
$yourInterval= new DateInterval( 'P1D'); //here you set interval per one day
$yourPeriodOfSevenDays= new DatePeriod( $now, $yourInterval, 7); // here you will set to what piriod of time get inerval
foreach($yourPeriodOfSevenDays as $day) {
$date = $day->format( 'd-m-Y');
$resultArray[] = $date ;
}
Now you will have all dates in array
array(8) { [0]=> string(10) "04-01-2014" [1]=> string(10) "05-01-2014" [2]=> string(10) "06-01-2014" [3]=> string(10) "07-01-2014" [4]=> string(10) "08-01-2014" [5]=> string(10) "09-01-2014" [6]=> string(10) "10-01-2014" [7]=> string(10) "11-01-2014" }

Answer 2

This is the simplest way I can think of:-
$lastWeek = new \DateTime('-7 days');
$interval = new \DateInterval('P1D');
$period = new \DatePeriod($lastWeek, $interval, new \DateTime());
var_dump(iterator_to_array($period));
See it working.
Even simpler, if you like one liners:-
$period = new \DatePeriod(new \DateTime('-7 days'), new \DateInterval('P1D'), new \DateTime());
var_dump(iterator_to_array($period));
See it working.
Then again, you can use a DatePeriod object in a foreach loop, so you may not need an array:-
$period = new \DatePeriod(new \DateTime('-7 days'), new \DateInterval('P1D'), new \DateTime());
foreach($period as $day){
echo $day->format('Y-m-d');
}
See it working

Answer 3

You could use DateTime::add.
$dateTime = new DateTime("now");
$dateInterval = new DateInterval('P1D');
$days = 7;
$resultArray = array();
for($i=0 ; $i<$days ; $i++){
$dateTime->add($dateInterval);
$resultArray[] = $dateTime->format('d-m-Y');
}
Result:
array(7) {
[0]=> string(10) "05-01-2014"
[1]=> string(10) "06-01-2014"
[2]=> string(10) "07-01-2014"
[3]=> string(10) "08-01-2014"
[4]=> string(10) "09-01-2014"
[5]=> string(10) "10-01-2014"
[6]=> string(10) "11-01-2014"
}
Edit:
My fault, i overread the description "one week ago".
Also you can use DateTime::sub
