如何判斷一個變量是否爲數字，如果是偶數？

Question

我需要腳本告訴我變量是否爲數字，如果是，是否是偶數。我的代碼到目前爲止：

 $Numbers = array("1", 2, "three", 4, 5, "six"); 

     foreach ($Numbers as $Value) { 
      if (is_numeric($Value)) { 
       if ($Value % 2 == 0) { 
        echo "$Value is numeric, and even"; 
       } else { 
        echo "$Value is numeric, but not even"; 
       } 
      } else { 
       echo "$Value is not numeric"; 
      } 

我的瀏覽器顯示一個空白頁。

任何幫助將不勝感激。

語法error.Close foreach循環

$Numbers = array("1", 2, "three", 4, 5, "six"); 

     foreach ($Numbers as $Value) 
     { 
      if (is_numeric($Value)) 
      { 
       if ($Value % 2 == 0) 
       { 
        echo "$Value is numeric, and even"; 
       } 
       else 
       { 
        echo "$Value is numeric, but not even"; 
       } 
      } 
      else 
      { 
       echo "$Value is not numeric"; 
      } 
}
