Answer 1

For PHP >= 5.2.0, I would do something like this:
$time_array = array('0' => '11:00:00',
'1' => '12:00:00',
'2' => '13:00:00',
'3' => '14:00:00',
'4' => '15:00:00',
'5' => '16:00:00');
echo "\nBefore:\n";
print_r($time_array);
$start = new DateTime('12:30:00');
$end = new DateTime('14:00:00');
// Magic starts here
foreach ($time_array as $key => $value) {
$datetime = new DateTime($value);
if ($datetime >= $start and $datetime <= $end)
unset($time_array[$key]);
}
// Magic finished
echo "\nAfter:\n";
print_r($time_array);
Yes, it works.

You can use this if you dont need to preserve indexes
error_reporting(E_ALL);
$array = array(
0 => '12:00:00',
1 => '12:15:00',
2 => '12:30:00',
3 => '12:45:00',
5 => '13:15:00',
6 => '13:30:00',
7 => '13:45:00',
8 => '14:00:00',
9 => '14:15:00',
10 => '14:30:00',
);
$from = '12:30:00';
$to = '14:00:00';
$filtered = array();
foreach($array as $key => $value) {
if ($value < $from || $value > $to) {
$filtered[] = $value;
}
}
var_dump($filtered);

$var_arr = array();
$time_arr = array('12:00:00','12:15:00','12:30:00','12:45:00','13:15:00',
'13:30:00','13:45:00','14:00:00','14:15:00','14:30:00');
$start = strtotime('12:30:00');
$end = strtotime('14:00:00');
foreach($time_arr as $arr):
if(strtotime($arr)<$start || strtotime($arr)>$end):
$var_arr[] = $arr;
endif;
endforeach;
print_r($var_arr);
