Check each value:

$newArray = array();
foreach($array as $key => $val){
    if(!(!$val[1] && !$val[2] && !$val[3])) {
        $newArray[$key] = $array[$key];
    }
}

print_r($newArray);

$array = array(
    array('Jan', 0, 0, 1), 
    array('Feb', 0, 1, 0), 
    array('Mar', 0, 0, 0), 
    array('Apr', 1, 1, 1)
);

foreach($array as $i => $a) {
    $save = false;
    foreach($a as $k => $v) {
        if($k == 0) continue; 
        if($v != 0) $save = true; 
    }
    if(!$save) unset($array[$i]);
}

var_dump(array_values($array));

2 番目のデータ構造を必要としない場合:

foreach ( $data as $i => $month ) {
  if ( $i == 0 ) { continue; }
  if (
    $month[1] == 0 &&
    $month[2] == 0 &&
    $month[3] == 0 
  ) {
    unset($data[$i]);
  } 
}

$Temp = array();

foreach ($Array as $Key=>$Value) 
  if ($Value[1]!=0 || $Value[2]!=0 || $Value[3]!=0)
    $Temp[$Key] = $Value;

$Array = $Temp;
