Description:
------------
$round = [
'round' => empty($current) ? 1 : $current['round'] + 3,
'type' => 'Public',
'starts' => empty($current) ? $_SERVER['REQUEST_TIME'] : floor($_SERVER['REQUEST_TIME'] / 86400) * 86400 + 72000,
'ends' => floor($_SERVER['REQUEST_TIME'] / 86400) * 86400 + 72000 + 864000,
'speed' => 25,
'build' => 2500,
'credits' => 4294967295,
'jackpot' => 100
];

lLater on in code..

$round = [
'round' => $current['round'] + 1,
'type' => 'Speed',
'starts' => floor($_SERVER['REQUEST_TIME'] / 86400) * 86400 + 72000,
'ends' => floor($_SERVER['REQUEST_TIME'] / 86400) * 86400 + 72000 + 172800,
'speed' => 100,
'build' => 2500,
'credits' => 0,
'jackpot' => 50
];

If the same variable is already assigned with different values 'type' => 'Speed' now equals 25 because it's now assuming I am calling onto the variable $round['speed'] instead of wanting the string 'Speed' and inputs it into its place.

Expected result:
----------------
I expect the $round = [ 'type' => 'Speed' ] to put the string Speed into the index 'type' of the $round variable instead of the value of $round['speed']

Actual result:
--------------
$round['type] = 25;

instead of 

$round['type'] = 'Speed';

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

If this is not a bug how would you go about assigning the value 'Speed' into the index 'type' without receiving the indexs value of 25?
 [2020-03-30 19:39 UTC] schmidtzilla at outlook dot com 
You are correct. When I inserted into database I didn't quote the variable and it somehow game me an unexpected result of 25.
 [2020-03-30 20:02 UTC] schmidtzilla at outlook dot com 
$db->exec("INSERT INTO rounds (type, starts, ends, speed, build, credits, jackpot) VALUES ($round[type], $round[starts], $round[ends], $round[speed], $round[build], $round[credits], $round[jackpot])");

Gives it a value of 25 because $round[type] is the string 'Speed' which when echoed out inside my exec without quotes inside of it is now fetching the default value of the databases speed column which happened to be 25 in the database and it inserted that value into the type column! Very much expected results! PHP is awesome! :D
