array_values.

An authoritative resource, too:

array_values($array);

Try with - 

$json = '{
    "2": "12:40 to 13:0",
    "3": "13:0 to 13:20",
    "4": "13:20 to 13:40",
    "5": "13:40 to 14:0",
    "6": "14:0 to 14:20",
    "7": "14:20 to 14:40",
    "8": "14:40 to 15:0",
    "9": "15:0 to 15:20",
    "10": "15:20 to 15:40",
    "11": "15:40 to 16:0",
    "12": "16:0 to 16:20",
    "13": "16:20 to 16:40",
    "14": "16:40 to 17:0",
    "15": "17:0 to 17:20",
    "16": "17:20 to 17:40",
    "17": "17:40 to 18:0"
}';

$data = (array)json_decode($json); //your json data
$data_values = array_values($data);//if you want array
$newStr = "{".implode(',', $data_values)."}"; // if you want string
$newJson = json_encode($data_values); //if you want json

try this

<?php 
$json = '{
    "2": "12:40 to 13:0",
    "3": "13:0 to 13:20",
    "4": "13:20 to 13:40",
    "5": "13:40 to 14:0",
    "6": "14:0 to 14:20",
    "7": "14:20 to 14:40",
    "8": "14:40 to 15:0",
    "9": "15:0 to 15:20",
    "10": "15:20 to 15:40",
    "11": "15:40 to 16:0",
    "12": "16:0 to 16:20",
    "13": "16:20 to 16:40",
    "14": "16:40 to 17:0",
    "15": "17:0 to 17:20",
    "16": "17:20 to 17:40",
    "17": "17:40 to 18:0"

}';

echo json_encode(array_values(json_decode($json, true)));
?>

{"12:40 to 13:0","13:0 to 13:20",.....} this is not valid json format when key does not in JOSN.

correct format is ["12:40 to 13:0","13:0 to 13:20","13:20 to 13:40".....]

I hope you want to remove the index from the JSON, here is the way:

$json = '{
    "2": "12:40 to 13:0",
    "3": "13:0 to 13:20",
    "4": "13:20 to 13:40",
    "5": "13:40 to 14:0",
    "6": "14:0 to 14:20",
    "7": "14:20 to 14:40",
    "8": "14:40 to 15:0",
    "9": "15:0 to 15:20",
    "10": "15:20 to 15:40",
    "11": "15:40 to 16:0",
    "12": "16:0 to 16:20",
    "13": "16:20 to 16:40",
    "14": "16:40 to 17:0",
    "15": "17:0 to 17:20",
    "16": "17:20 to 17:40",
    "17": "17:40 to 18:0"
    }';
 $json = json_encode(array_values(json_decode($json,true)));

Yes, you can remove keys and keep just values using PHP's array_values

Just do json_decode and then use array_values.

By default, array indexes are numeric.

If you generate the array e.g. $arr = array('PHP', 'JAVA'), you will get

This is numeric array

$arr = (0 => 'PHP', '1' => 'JAVA')

Now, if we create a new associative array.

$arr = ('scripting' => 'PHP', 'programming' => 'JAVA')

So, array_values converts the array into numeric array from associative array.
