Message:

I have this array with year as its key and count as its value,

$dateRange = array([

   "1990" => 10,

   "1991" => 12,

   "1992" => 12,

   "1993" => 12,

   "1994" => 12,

   "1995" => 12,

   "1996" => 6

]);

and how can I make it look like this *(getting consecutive year/s with a count/value of 12 then count its total value)

$dateRange = ([

    "1990" => 10,

    "1991-1995" => 60,

    "1996" => 6

]);

My Answer:
"2019" => 5,
"2020" => 8,
"2021" => 5,
"2022" => 3,
"2023" => 2,
"2024" => 8
);

To group the values by count, you can use the following PHP code:

php
$groupedArray = [];

foreach ($dateRange as $year => $count) {
if (!isset($groupedArray[$count])) {
$groupedArray[$count] = [];
}

$groupedArray[$count][] = $year;
}

print_r($groupedArray);


This code will output an array where the keys are the counts and the values are arrays of years with that count.
