打印的MySQL查詢與PHP結果在HTML頁面中

Question

我有一個簡單MySQL query：SELECT COUNT(column_name) FROM my_table

如何print results (in html pages)與PHP在已有的數據庫連接？ 對不起，這個愚蠢的答案，我只是學習PHP :(

Answer 1

$query = "SELECT COUNT(column_name) AS count FROM my_table"; 
$sql = mysql_query($query); 
$result = mysql_fetch_assoc($sql); 
echo "<p>" . $result['count'] . "</p>"; 

應該做的工作

注：我用AS count才能訪問它更容易關聯數組中

Answer 2

。

簡單地

<? 
//Connect to the database 
$sql = "SELECT COUNT(column_name) as total FROM my_table"; 
$result = mysql_query($sql); 
$row = mysql_fetch_array($sql); 
echo $row['total']; 
?> 

Answer 3

$sql = mysql_query("SELECT COUNT(column_name) AS count FROM my_table"); 
$result = mysql_fetch_assoc($sql); 
echo '<p>'. $result['count'] .'</p>';
