顯示html網頁thorugh php？

我剛剛開始PHP並試圖設計一個簡單的代碼，我定義了一些隨機生成的多維整數數組並將它們顯示到網頁上。顯示html網頁thorugh php？

但是，當我嘗試訪問服務的Apache時，網絡瀏覽器不顯示網頁。我的代碼中缺少什麼？

<html> 
    <head> 
     <title> 
     Novatos del PHP 
     </title> 
    </head> 

    <body> 



    <?php 

     $m1 = array ( array (rand(0,100), rand(0,100), rand(0,100)), 
         array (rand(0,100), rand(0,100), rand(0,100)), 
         array (rand(0,100), rand(0,100), rand(0,100)), 
         array (rand(0,100), rand(0,100), rand(0,100)) 
        ); 

     $m2 = array ( array (rand(0,100), rand(0,100), rand(0,100)), 
         array (rand(0,100), rand(0,100), rand(0,100)), 
         array (rand(0,100), rand(0,100), rand(0,100)), 
         array (rand(0,100), rand(0,100), rand(0,100)) 
        ); 

     printMatrix($m1); 


     function printMatrix($matrix){ 
      echo "<table width=\"200\" border=\"1\">"; 

      foreach($matrix as $row =$rValue){ 
       echo "<tr>"; 
       foreach($rValue as $col =$cValue){ 
        echo "<td>".$cValue."</td>"; 
       } 
       echo "</tr>"; 
      } 
      echo "</table>"; 
     } 

    ?> 



    </body> 
</html>
