How get quantity of specific values in an array?

Question

I have an multi-dimensional array. I want to get count of specific values in all arrays. This arrays in the main array depend on how many comments that I have added.

Here is my array:

array(3) {
  [0]=>
  array(11) { 
    ["comment_id"]=> string(1) "1" 
    ["user_Id"]=> string(1) "2" 
    ["comment"]=> string(18) "Commented! edited!" 
    ["comment_datetime"]=> string(19) "2015-02-20 04:24:28" 
    ["update_at"]=> string(19) "2015-02-20 04:23:18" 
    ["user"]=> string(18) "Nishan Weerasinghe" 
    ["delete"]=> string(1) "0" 
    ["username"]=> string(6) "Nishan" 
    ["picture_id"]=> NULL 
    ["picture"]=> NULL 
    ["picture_ext"]=> NULL 
  } 

  [1]=> 
  array(11) { 
    ["comment_id"]=> string(2) "48" 
    ["user_Id"]=> string(1) "2" 
    ["comment"]=> string(4) "here" 
    ["comment_datetime"]=> string(19) "2015-02-23 12:58:00" 
    ["update_at"]=> string(0) "" 
    ["user"]=> string(18) "Nishan Weerasinghe" 
    ["delete"]=> string(1) "0" 
    ["username"]=> string(6) "Nishan" 
    ["picture_id"]=> NULL 
    ["picture"]=> NULL 
    ["picture_ext"]=> NULL 
  } 
  [2]=> 
  array(11) { 
    ["comment_id"]=> string(2) "49" 
    ["user_Id"]=> string(1) "2" 
    ["comment"]=> string(3) "dfg" 
    ["comment_datetime"]=> string(19) "2015-02-23 14:46:56" 
    ["update_at"]=> string(0) "" 
    ["user"]=> string(18) "Nishan Weerasinghe" 
    ["delete"]=> string(1) "1" 
    ["username"]=> string(6) "Nishan" 
    ["picture_id"]=> NULL 
    ["picture"]=> NULL 
    ["picture_ext"]=> NULL 
  }
}

I want to get a count of how many ["delete"]=> 0 (answer should be 2 according to this ex.) are there in the main array.

where are your attempts? count + array_filter or good ol' foreach should suffice — Kevin

$counter = 0;
foreach($results as $result){
    if($result['delete'] == "0"){
        $counter++;
    }
}
echo $counter;

Like the comment said a simple foreach and some math.

just use foreach

$count=0;  
foreach($yourarray as $a){

  if($a['delete']=='1')
      $count++;

}

You can do it with functions like this (Need PHP > 5.5.0):

echo array_count_values(array_column($array_string, 'delete'))[0];

Just apply foreach loop as follows:

$count = 0;
foreach($yourarray as $counter){
    if($counter['delete'] == "0"){
        $count++;
    }
}
echo $count;
