Question

working on a script, that calculates the difference between dates retrieved from an API. I want it to then drop in an image as many times as the difference.

$d1 = new DateTime('2012-04-04');
$d2 = new DateTime('2012-03-31');

$interval = $d1->diff($d2);

Ive tried to have a go with a for loop but with no success

for ($i = 0 $i <= $interval; $i++) 
{ 
  echo = "<img src=\"test.jpg"/";
}

can you guys see any problems?

I find PHP’s DateTime works better when you use the modify() method instead of normal arithmetic.
Assuming you want one image per day:

$d1 = new DateTime('2012-04-04');
$d2 = new DateTime('2012-03-31');    

while($d2 <= $d1)
{
     echo "<img src=\"test.jpg\">";
     $d2->modify("+1 day");
}
