If you want to remove the first items in the array for the key name Provinces and the numerical keys do not have to be preserved, you could also use array_splice:
$arr = [
"Country" => "Canada",
"Provinces" => [
"Quebec",
"Ontario",
"British Columbia"
]
];
array_splice($arr["Provinces"], 0, 1);
Or using unset to keep the numerical keys:
unset($arr['Provinces'][0]);

You can do that with unset():
unset( $myArray['Cities'][0] )

You can do both way but difference is that when you use unset will remove an element by its key, say unset( $myArray['country']) will remove the country key value pair.
if you want to remove first element in multidimensional array then you can easily d t with array_shift(); it will remove all the child array of this particular element.
suppose it is a location array
$location = Array
(
[Country] => Canada
[Provinces] => Array
(
[0] => Quebec
[1] => Ontario
[2] => British Columbia
)
)
// Removing first array item
$location_new = array_shift($planets);
print_r($location_new);//it will give **Canada**
//and now
print_r($location);//it will give the
Array
(
[Provinces] => Array
(
[0] => Quebec
[1] => Ontario
[2] => British Columbia
)
)
