Better way will be to get array of values and use array-count-values:

$array = [
        ['someKey' => 'Value 1'],
        ['someKey1' => 'Value 1'],
        ['someKey2' => 'Value 2'],
        ['someKey3' => 'Value 3'],
    ];

$arr = array_map(function ($e) {return reset($e);},$array);
print_r(array_count_values($arr));

Output will be:

Array
(
    [Value 1] => 2
    [Value 2] => 1
    [Value 3] => 1
)

I just improve @Qirel answer. This version can support multi-value to count. Live demo: 3v4l

Loop the array, pick the first value using reset(), and count that index of the $result array. 

$array = [
        ['someKey' => 'Value 1'],
        ['someKey1' => 'Value 1'],
        ['someKey2' => 'Value 2'],
        ['someKey3' => 'Value 3'],
    ];

$result = [];

foreach ($array as $v) {
    $value = reset($v);
    if (!isset($result[$value]))
        $result[$value] = 0;

    $result[$value] += 1;
}
print_r($result);

First flip thekey with value and then loop the array to incrment the counters :

Try this snippet :

$chromi = 0 ;
$detruch = 0 ;
$detroy = 0;
$data = array_flip($data);
foreach($data as $key=>$value){
      if($key=='chromi'){
        $chromi++;
      }
      else if ($key=='chromi'){
      $chromi++
       }
        else if ($key=='detroy'){
      $detroy++
       }
}
