Answer 1

Try
$result = array();
foreach($arr as $ar){
$date = DateTime::createFromFormat("Y-m-d", $ar['event_date']);
$month = $date->format('F');
$year = $date->format('Y');
$result[$year][$month][] = $ar;
}
See demo here

Answer 2

$res= array();
foreach($arr as $key => $val) // $arr is your actual array
{
$month = date('F-Y', strtotime($val['event_date']));
$res[$month][] = $val;
}
Now you get will result as
[January-2014] = array(a1,a2...)
[December-2014] = array(a1,a2...)

Answer 3

Here I only suggest how to sort an array by date. I hope you can do the rest of the work yourself.
function cmp($a, $b) {
return (new DateTime($a['event_date']))->getTimestamp() < (new DateTime($b['event_date']))->getTimestamp()? -1 : 1;
}
usort($array, 'cmp');
$curr_month = 0;
foreach ($array as $elem) {
// output elements of array based on month
// ...
}
