php - count array value with condition -

-

i have array data contain values. want count particular key value.

my array :

array (     [0] => stdclass object         (             [id] => 3             [product_id] => 42             [user_id] => 69             [order_item_id] => 0             [sku_id] => 78             [rate] => 4 // count             [description] => wonderful dress.             [is_certifiedbuyer] => 1             [status] => 1             [deleted] => 0             [created_at] => 2016-03-11 16:53:31             [updated_at] => 2016-03-11 16:53:31             [username] => hiral             [productname] => aish dress         )      [1] => stdclass object         (             [id] => 4             [product_id] => 42             [user_id] => 12             [order_item_id] => 0             [sku_id] => 78             [rate] => 2             [description] => greate dress.             [is_certifiedbuyer] => 1             [status] => 1             [deleted] => 0             [created_at] => 2016-03-11 16:53:31             [updated_at] => 2016-03-11 16:53:31             [username] => admin             [productname] => aish dress         )  )

from above array want count total 5 rated user, total 4 rated user, total 3 rated... etc

in short want count rate field above array.

i have tried :

        $reviews=$this->productreviewrepo->productreview(42);          $div1 = array_filter($reviews, function($review) {              return  substr('4', $review->rate) !== false;         });         echo '<pre>';print_r(count($div1));         $div2 = array_filter($reviews, function($review) {              return substr('4', $review->rate) !== false;         });         echo '<pre>';print_r(count($div2));         $div3 = array_filter($reviews, function($review) {              return substr('3', $review->rate) !== false;         });         echo '<pre>';print_r(count($div3));         $div4 = array_filter($reviews, function($review) {              return substr('2', $review->rate) !== false;         });         echo '<pre>';print_r(count($div4));         $div5 = array_filter($reviews, function($review) {              return substr('1', $review->rate) !== false;         });

but error of can count string , integer value.

i think give better performance. declare variables $count1, $count2 ... before loop. keep increment respective variable based on rating value. using $value->rate objects inside array.

foreach ($myarray $key => $value) {     switch ($value->rate) {         case '1':             $count1++;              break;         case '2':             $count2++;              break;         case '3':             $count3++;              break;         case '4':             $count4++;              break;         case '5':             $count5++;              break;          default:             break;     } }

why better performance

when use array_filter, loops on array. so, when use many array_filter, looping multiple times. but, approach can accomplish 1 loop on array.
