PHP - Loop through dates

[T0d]

I'm wondering the most efficient/fastest way to loop through two given dates and pull-out each respective date.
IE: User inputs: 11/25/07 and 12/25/07
I want to go through and pull out each day in between.

MKTIME? What would you do and why.

Here's what I have it seems pretty sloppy though.

PHP Code:

$year1 = '2007';
$month1 = '11';
$day1 = '25';

$year2 = '2007';
$month2 = '12';
$day2 = '25';

    $start_date = "$year1-$month1-$day1";
    $end_date    = "$year2-$month2-$day2";
    
    $date = mktime(0,0,0,$month1,$day1,$year1); //Gets Unix timestamp START DATE
    $date1 = mktime(0,0,0,$month2,$day2,$year2); //Gets Unix timestamp END DATE
    $difference = $date1-$date; //Calcuates Difference
    $daysago = floor($difference /60/60/24); //Calculates Days Old

    echo "Total Days Between: ".$daysago;

$i = 0;
while ($i <= $daysago +1) {
    if ($i != 0) { $date = $date + 86400; }
    else { $date = $date - 86400; }
    $today = date('Y-m-d',$date);
    echo "$i) Day: $today <br>";
    $i++;
}

Cool. Looks nice.

As it turned out in my program I didn't need to actually do the -# and a few other minor changes, works though.

I stumbled upon this thread looking to do the same thing and although this thread is a bit old, but I thought I'd drop in my two cents.

I was able to accomplish the same thing like this:

PHP Code:

$start_date = '2008-03-01';
$check_date = $start_date;
$end_date = '2008-03-14';

while ($check_date != $end_date) {
    $check_date = date ("Y-m-d", strtotime ("+1 day", strtotime($check_date)));
    echo $check_date . '<br>';
} 


You'll probably want to build some error checking into this so you don't create an infinite loop, something like the following would work:

PHP Code:

$start_date = '2008-03-01';
$check_date = $start_date;
$end_date = '2008-03-14';

$i = 0;

while ($check_date != $end_date) {
    $check_date = date ("Y-m-d", strtotime ("+1 day", strtotime($check_date)));
    echo $check_date . '<br>';

    $i++;
    if ($i > 31) { die ('Error!'); }
} 


From here you would use $check_date to do what you want. Of course you can format these dates anyway you wish thanks to the wonderful php date() function.
