如何在此MySQL查詢中獲得每個結果的計數？

Question

我有一張表，其中每行跟蹤有關鏈接何時被點擊的詳細信息。該查詢顯示，前5頁，用戶是在當他們點擊鏈接：

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

foreach($pop_pages as $page) { 

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

} 

這將使前5名最頻繁點擊的URL列表。如何在此查詢中添加點擊次數的次數？

喜歡的東西：

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

Answer 1

試試這個：

$pop_pages = ("SELECT url, count(url) as c FROM clicks WHERE link = '$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

你可以做這樣的事情：

$pop_pages = ("SELECT url, COUNT(*) as count FROM clicks WHERE link = '$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>"; 

}
