I have an array 

        $rel = array('grandfather' => 0 ,
                    'grandmother' => 0 ,
                    'father' => 0 ,
                    'sister' => 0 ,
            );

I want it to compare to the array $family from

    $data['family'] = $facebook->api('/me/family?fields=name,relationship,education,location,cover');

using the foreach loop

     foreach ($family as $families) {

            foreach ($families as $fams) {

                $id = $fams['id'];  
                $name = $fams['name'];

                $relationship = $fams['relationship'];

                foreach($rel as $k => $val){

                    if($k == $relationship)
                    {
                        $val += 1;
                    }
                }
            }
        }

i want the $val to increment in each iteration such that if I have 5 sisters.. when i will 

print_r($rel);

the result would be

Array ( [grandfather] => 0 [grandmother] => 0 [father] => 0 [sister] => 5 )

i have tried the above code but it still returns to 0..

foreach($rel as $k => $val) in here, $k is the index; if the index of the array is numbered (instead of text: $array(0 => "value") instead of $array("txt" => "value");) the $k will represent a number. Otherwise you could always attach a $inc=0 before the foreach and then $inc++ within the foreach – MoshMage Aug 26 '14 at 9:06

try this 

if($k == $relationship)
{
   $rel[$k] += 1;
}

It should work.

foreach ($family as $families) {

        foreach ($families as $fams) {

            $id = $fams['id'];  
            $name = $fams['name'];

            $relationship = $fams['relationship'];

            foreach($rel as $k => $val){

                if($k == $relationship)
                {
                    $rel[$relationship]++;
                }
            }
        }
    }
