Please check with following code

$source=array( 
    "0" => array(  "status_change" => "start", "clock_status" => "1" ),
    "1" => array(  "status_change" => "stop", "clock_status" => "2" ),
    "2" => array(  "status_change" => "stop", "clock_status" => "2" ),
    "3" => array(  "status_change" => "stop", "clock_status" => "2" ),
    "4" => array(  "status_change" => "stop", "clock_status" => "2" ),
    "5" => array(  "status_change" => "stop", "clock_status" => "2" ),
    "6" => array(  "status_change" => "stop", "clock_status" => "2" ),
    "7" => array(  "status_change" => "start", "clock_status" => "1" ),
    "8" => array(  "status_change" => "stop", "clock_status" => "2" ),

    "12" => array(  "status_change" => "start", "clock_status" => "1" )
    );

function reduce_successive(&$source) {      
    $prev_status="none";
    foreach($source as $key=>$item) {
        if($item['status_change'] == $prev_status) {
            unset($source[$key]);
        } else {
            $prev_status = $item['status_change'];
        }
