PHP“意外结束”

我得到的错误：
解析错误：语法错误,意外$end在/home/tennox/public_html/php/kalender.php第46行

我试图做一个计算复活节星期日的函数,在另一个脚本中没有其他所有它只是起作用,但在这个没有.另一种方式围绕同样的事情！

<?php
$year = isset($_POST['year']) ? intval($_POST['year']) : date('Y');
$months = array("","Januar","Februar","M?rz","April","Mai","Juni","Juli","August","September","Oktober","November","Dezember");
$days = array('So','Mo','Di','Mi','Do','Fr','Sa');
$ostern = getOsterSonntag($year);
?>

      $date = strtotime("$y.$x.$year");
      $day = date("d",$date);
      $dayname = $days[date("w",$date)];

      if ($y == 0) {
         echo "<div align="center"><b>$months[$x]</b></div>";
      } elseif ($y < date("t",$date) && !($y == 30 && $x == 2)) {

            echo "<b>";
         echo "$day $dayname";
         if ($date == $ostern)
