php array foreach loop data manipulation -


i have script gets data mongodb in form of array , show results. array has many records. sample array follows:

array(2) {   ["mac"]=> string(17) "2c:33:7a:10:f8:39" int(1478199995) ["duration"]=> int(5) }  array(2) {   ["mac"]=> string(17) "38:0b:40:ad:03:53" int(1478203338) ["duration"]=> int(3) }  array(2) {   ["mac"]=> string(17) "38:0b:40:ad:03:53" int(1478201111) ["duration"]=> int(7) }  array(2) {   ["mac"]=> string(17) "2c:33:7a:10:f8:39" int(1478206709) ["duration"]=> int(7) }  array(2) {   ["mac"]=> string(17) "38:0b:40:ad:03:53" int(1478202821) ["duration"]=> int(6) }  array(2) {   ["mac"]=> string(17) "2c:33:7a:10:f8:39" int(1478202366) ["duration"]=> int(4) }  array(2) {   ["mac"]=> string(17) "38:0b:40:ad:03:53" int(1478205023) ["duration"]=> int(2) }

i showing record respect mac address in above array mac address "2c:33:7a:10:f8:39" has 3 records , "38:0b:40:ad:03:53" has four, add duration of each record , show on browser this

2c:33:7a:10:f8:39          16sec 38:0b:40:ad:03:53          18sec

i doing following logic think slow 5000 6000 records.

i first mac address in array , remove duplication , run loop on array , add duration specific mac code below.

<?php  foreach ($cursor $document) {  array_push($arr,$document["mac"]);  }  $arr=array_unique($arr);  $duration=0;  for($i=0;$i<count($arr);$i++){   foreach ($cursor $document) {  if($document["mac"]==$arr[$i])  {   $duration+=$document['assoc_time'];   }   echo $arr[$i]."      ".$duration;   }  ?>

how can make process fast , how perform task in 1 foreach loop.

you should let mongodb summing. mdb query missing, see https://docs.mongodb.com/v3.2/reference/operator/aggregation/sum/
