php - Opposite condition producing required results in If Else statement -


supposing have following array 

[agent - 134] => array         (             [0] => array                 (                     [0] => 2015-07-14 12:03:33.089210                     [1] => connect                 )              [1] => array                 (                     [0] => 2015-07-14 12:03:55.053394                     [1] => completeagent                 )              [2] => array                 (                     [0] => 2015-07-14 12:07:29.913989                     [1] => connect                 )              [3] => array                 (                     [0] => 2015-07-14 12:07:56.693848                     [1] => completecaller                 )              [4] => array                 (                     [0] => 2015-07-14 12:09:02.989649                     [1] => connect                 )              [5] => array                 (                     [0] => 2015-07-14 12:09:35.608860                     [1] => completeagent                 )              [6] => array                 (                     [0] => 2015-07-14 12:11:56.564747                     [1] => connect                 )              [7] => array                 (                     [0] => 2015-07-14 12:12:25.979910                     [1] => completeagent                 )              [8] => array                 (                     [0] => 2015-07-14 12:20:15.130092                     [1] => connect                 )              [9] => array                 (                     [0] => 2015-07-14 12:20:45.843112                     [1] => completeagent                 )          )

and trying calculate difference between events. condition complete event if previous array's second element connect , next array's second element either completeagent or completecaller. have written following code loop through testing purposes if statement should fulfill condition yet else works leads me believe there might wrong in syntax comparison i'm unsure of.

foreach ($ttt_array $tkey => $value) {         $ttt_total = 0;         ($i = 0; $i < count($value);         ) {             if (($value[$i][1] === "connect" && $value[$i + 1][1] === "completeagent") || ($value[$i][1] === "connect" && $value[$i + 1][1] === "completecaller")) {                 $i+=1;                 echo $i;             } else {                  $srttime = strtotime($value[$i][0]);                 echo "start-time" . $srttime . "<br>";                 $endtime = strtotime($value[$i + 1][0]);                 echo "end-time" . $endtime . "<br>";                 $interval = $endtime - $srttime;                 echo "interval" . $interval . "<br>";                 $ttt_total += $interval;                 $i+=2;             }         }         $ttl_talk_total[$tkey] = timeconverter($ttt_total);     }

where $ttt_array array show above. incorrect if statement?

"compeleteagent" <== error? "compeletecaller" <== this
