從數據庫中收集表名的列名

Question

獲取數據庫表的列名並在PHP頁面中顯示它們的最佳方式是什麼？我只能收集並顯示錶格行。

$connection = mysql_connect('localhost', 'root', ''); 
mysql_select_db('...'); 
$query = "SELECT * FROM ..."; 

$result = mysql_query($query); 

echo "<table class='table'>"; 
echo '<tr>'; 
for ($i = 0; $i < mysql_num_fields($result); $i++) { 
    echo "<th>".mysql_field_name($result, $i)."</th>"; 
} 
echo '</tr>'; 
while($row = mysql_fetch_array($result)){ 
echo "<tr class='info'><td>" . $row['name'] . "</td> 
       <td>" . $row['mail'] . "</td> 
       <td>" . $row['number'] . "</td> 
       <td>" . $row['price'] . "</td> 
       <td>" . $row['paymenttype'] . "</td> 
       <td>" . $row['pcname'] . "</td> 
       </tr>"; 
} 
echo "</table>"; 
mysql_close(); 
?>
