Your point structure does not match up with your sentence.
So I’ll answer:
To reach level 2 50 XP is needed. To reach level 3 a further 55 XP is
needed. To reach level 4 a further 60 XP is needed and so forth.
<?php
$get_level = function () {
foreach (range(0, 300, 50) as $difficulty => $base) {
yield [$base + ($difficulty * 5) => 'Level '.($base / 50)];
}
};
foreach ($get_level() as $base => $level) {
echo print_r($level, true);
}
Result:
Array
(
[0] => Level 0
)
Array
(
[55] => Level 1
)
Array
(
[110] => Level 2
)
Array
(
[165] => Level 3
)
Array
(
[220] => Level 4
)
Array
(
[275] => Level 5
)
Array
(
[330] => Level 6
)
