Using string functions:

$temp = explode('-',$testArray[0]);
        $start_str = $temp[0];
        $comma = '';

for ($i = 0; $i <= count($testArray); $i++) {

        $temp = explode('-',$testArray[$i]);

        $prev_start = $temp[0];
        $prev_end = $temp[1];
        $prev_endtime = (integer) $prev_end;

        $temp = explode('-',$testArray[$i+1]);
        $start = $temp[0];
        $end = $temp[1];

        $starttime = (integer) $start;
        if($prev_endtime != $starttime){
            $op .= " $comma $start_str - $prev_end";
             $comma = ',';
            $start_str = $start;
        }
}
echo $op;
