Question

I want to run a while(or any) loop to output a small list of dates as an array

$start = $day = strtotime("-1 day");
$end = strtotime('+6 day');
while($day < $end)
{
    echo  date('d-M-Y', $day) .'<br />';
    $day = strtotime("+1 day", $day) ;
}

This works fine for printing, but I want to save it as an array (and insert it in a mysql db).
Yes! I don’t know what I’m doing.

Answer 1

to create a array, you need to first initialize it outside your loop (because of variable scoping)

$start = $day = strtotime("-1 day");
$end = strtotime('+6 day');
$dates = array(); //added
while($day < $end)
{
    $dates[] = date('d-M-Y', $day); // modified
    $day = strtotime("+1 day", $day) ;
}
echo "<pre>";
var_dump($dates);
echo "</pre>";

you can then use your dates using either foreach or while

foreach approach :

foreach($dates as $date){
     echo $date."<br>";
}

while approach :

$max =  count($dates);
$i = 0;
while($i < $max){
    echo $dates[$i]."<br>";
}
