I need to remove element between $StartTime and $EndTime
so for "Lun" array need to be removed:
[0] => 10:00
[1] => 11:00
[2] => 12:00
[3] => 13:00
[4] => 14:00 // need remove
[5] => 15:00 // need remove
[6] => 16:00 // need remove
[7] => 17:00
[8] => 18:00
[9] => 19:00
[10] => 20:00
I would to foearch the time from Start to End date, and then remove with:
unset($DisponibilitaRoom[$Nomeroom]["IntervalTime"]["Lun"][$index]);

Answer 1

You correct - simple unset should do it - but you need to loop on the times and remove them as:
foreach($arr['Tennis 1']['IntervalTime']['Lun'] as $k => $v) {
if ($v >= $StartTime && $v < $EndTime)
unset($arr['Tennis 1']['IntervalTime']['Lun'][$k]);
}
Live example: 3v4l
Or you can use array-filter as
$arr['Tennis 1']['IntervalTime']['Lun'] = array_filter($arr['Tennis 1']['IntervalTime']['Lun'], function ($v) use ($StartTime, $EndTime) {
return !($v >= $StartTime && $v < $EndTime);
} );

Answer 2

You can use array_walk_recursive with array_map and array_filter
array_walk_recursive($a['Tennis 1']['IntervalTime'], function(&$v) use ($StartTime, $EndTime){
if($v >= $StartTime && $v <= $EndTime) $v = false;
});
$f['Tennis 1']['IntervalTime'] = array_map('array_filter', $a['Tennis 1']['IntervalTime']);
print_r($f);
