foreach($result as $word => $count1) 
{ 
    if (in_array($word, $blacklist)) continue; 


    echo '<tr>';  
    echo '<td>'; 
    echo "$word"; 
    echo '</td>'; 

    echo '<td>'; 
    echo "$count1 "; 
    echo '</td>'; 

    echo '</tr>'; 

    } 

    echo "</table>"; 

Answer 1

$rows = 0; 
foreach($result as $word => $count1) 
{ 
    if($rows >= 5) break; 
    if (in_array($word, $blacklist)) continue; 
    $rows++; 
    //... 
} 

Answer 2

使用計數器。

$i=0; 
foreach($result as $word => $count1) 
{ 
if (in_array($word, $blacklist)) continue; 

if($i>=5) 
break; 
echo '<tr>';  
echo '<td>'; 
echo "$word"; 
echo '</td>'; 

echo '<td>'; 
echo "$count1 "; 
echo '</td>'; 

echo '</tr>'; 
$i++; 
} 

echo "</table>";
