爲什麼的mysql_query執行多次

Question

我有一個函數，並在其中一個更新查詢是這樣的：

//Article Function 
function article() 
{ 
    if($_GET['action'] == "article" && !empty($_GET['id'])) 
    { 
     $id = intval($_GET['id']); 
     $article = array(); 
     $selectArticle = mysql_query("SELECT * FROM articles WHERE id='$id'"); 
     $rowArticle = mysql_fetch_array($selectArticle); 

     $id = $rowArticle['id']; 
     $title = stripcslashes($rowArticle['title']); 
     $category = stripcslashes($rowArticle['category']); 
     $image = stripcslashes($rowArticle['image']); 
     $description = stripcslashes($rowArticle['description']); 
     $full_description = stripcslashes($rowArticle['full_description']); 
     $keywords = stripcslashes($rowArticle['keywords']); 
     $url = "/article/" . $rowArticle['id'] . "/" . str_replace(" ","-",stripcslashes($rowArticle['title'])); 
     $article = array('id' => $id, 'title' => $title, 'category' => $category, 'image' => $image, 'description' => $description, 'full_description' => $full_description, 'keywords' => $keywords, 'url' => $url); 
     mysql_query("UPDATE articles SET visits=visits+1 WHERE id='7'"); 
    } 
    return $article; 
} 

只調用一次的功能，但在查詢運行多次，當我刷新頁面。

例如在第一負載的訪問柱是24和刷新訪問後柱是48 !!!!!!

我無法理解爲什麼我混了

Answer 1

1..Use頭和重定向頁面。

header("Location:your_page.php"); 

2您可以重定向到相同的頁面或不同的頁面。

Unset $_POST after inserting it to Database. 
    unset($_POST);
