如何获取此MySQL查询中每个结果的计数？

Question

我有一个表，其中的每一行都跟踪有关单击链接的时间的详细信息。 此查询显示用户单击链接时所在的前5页：

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

foreach($pop_pages as $page) {

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

}

这将列出前5个最常点击的URL。 如何添加此查询中点击次数的计数？

就像是：

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

Answer 1

尝试这个：

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

您可以执行以下操作：

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

}
