如何獲取此MySQL查詢中每個結果的計數？

Question

我有一個表，其中的每一行都跟蹤有關單擊鏈接的時間的詳細信息。 此查詢顯示用戶單擊鏈接時所在的前5頁：

$pop_pages = ("SELECT url FROM clicks WHERE link = '$link_id' GROUP BY url ORDER BY url ASC LIMIT 5");

foreach($pop_pages as $page) {

$page_string = $page_string."<li>".$page->url."</li>";

}

這將列出前5個最常點擊的URL。 如何添加此查詢中點擊次數的計數？

就像是：

$page_string = $page_string."<li>".$page->url." (X clicks)</li>";

Answer 1

嘗試這個：

$pop_pages = ("SELECT url, count(url) as c FROM clicks WHERE link = '$link_id' GROUP BY url ORDER BY url ASC LIMIT 5");

foreach($pop_pages as $page) {

$page_string = $page_string."<li>".$page->url." (".$page->c." clicks)</li>";

}

Answer 2

您可以執行以下操作：

$pop_pages = ("SELECT url, COUNT(*) as count FROM clicks WHERE link = '$link_id' GROUP BY url ORDER BY url ASC LIMIT 5");

foreach($pop_pages as $page) {

  $page_string = $page_string."<li>".$page->url." (".$page->count." clicks)</li>";

}
