Counting values in the same level of a multidemensional array - php

Question

I'm trying to count how many of the same calendar weeks I have inside the same level of a multidimensional array. My start array can be seen on the picture on the left part, my output is composed of an ID [0] and the rest are the dates corresponding to that ID.
On my code I convert these dates to calendar weeks and then try to count them with a foreach loop and then unset the last values if they are identical to the newest ones, so that I only have the final count. My Problem is that as you can see on the last array [1975]->1->1 the count is not right, it is taking in count also the same weeks from the other ID.
Any kind of help is much appreciated!
My code looks like this:
$array= array();
$arrayCount=array();
$j=0;
foreach ($sorted as $value) {
$k=1;
foreach ($value[1] as $match) {
$time = strtotime($match);
$Calendar_Week = date('W',$time);
$Year = date('Y',$time);
if(!array_key_exists($Calendar_Week , $array)){
$i=1;
$array[$Calendar_Week][$j]=$match;
}
$arrayCount[$sorted[$j][0]][1][0]=$sorted[$j][0];
$arrayCount[$sorted[$j][0]][1][$k][]=$i;
$arrayCount[$sorted[$j][0]][1][$k][]=$Calendar_Week;
$arrayCount[$sorted[$j][0]][1][$k][]=$Year;
// Delete previous counts of the same value
if ($arrayCount[$sorted[$j][0]][1][$k-1][1]==$Calendar_Week & $arrayCount[$sorted[$j][0]][1][$k-1][2]==$Year) {
unset($arrayCount[$sorted[$j][0]][1][$k-1]);
}
$i++;
$k++;
}
$j++;
}
dd($sorted, $arrayCount);

You just need to reset the $i and $array inside the foreach loop
$i=1;
$array = array();
Please check this code
$array= array();
$arrayCount=array();
$j=0;
foreach ($sorted as $value) {
$k=1;
$i=1;
$array = array();
foreach ($value[1] as $match) {
$time = strtotime($match);
$Calendar_Week = date('W',$time);
$Year = date('Y',$time);
if(!array_key_exists($Calendar_Week , $array)){
$i=1;
$array[$Calendar_Week][$j]=$match;
}
$arrayCount[$sorted[$j][0]][1][0]=$sorted[$j][0];
$arrayCount[$sorted[$j][0]][1][$k][]=$i;
$arrayCount[$sorted[$j][0]][1][$k][]=$Calendar_Week;
$arrayCount[$sorted[$j][0]][1][$k][]=$Year;
// Delete previous counts of the same value
if ($arrayCount[$sorted[$j][0]][1][$k-1][1]==$Calendar_Week & $arrayCount[$sorted[$j][0]][1][$k-1][2]==$Year) {
unset($arrayCount[$sorted[$j][0]][1][$k-1]);
}
$i++;
$k++;
}
$j++;
}
dd($sorted, $arrayCount);
