php显示COUNT的结果？我认为

Question

我正在尝试弄清楚如何在下面的while循环中显示用户名列，以及计算每个用户有多少次点击。

 $query = "SELECT company, COUNT(company) FROM tableName GROUP BY company"; 
 $result = mysql_query($query) or die(mysql_error());

 // Print out result
 while($row = mysql_fetch_array($result)){
 echo "There are ". $row['COUNT(company)'] ."
 ". $row['company'] ." hits total so far";
 echo "<br />";

 }

例如

 There are 3 facebook hits total so far - user1(1 total), user2(1 total), user3(1 total)
 There are 2 google hits total - user1(2 total)
 There are 6 mircosoft hits total - user3(1 total)
 There are 0 dropbox hits total

感谢您提供的任何帮助！

Answer 1

您想要的基本数据来自：

SELECT company, userid, COUNT(*)
FROM tableName
GROUP BY company, userid;

您想要的格式近似为：

SELECT company, GROUP_CONCAT(userid, '(', cnt, ' total)')
FROM (SELECT company, userid, COUNT(*) as cnt
      FROM tableName
      GROUP BY company, userid
     ) cu
GROUP BY company;

当然，这对“dropbox”没有一行。对于该功能，您需要一个包含感兴趣公司的表格，您需要LEFT JOIN来查询此信息。

正如其他人可能会注意到的那样，“mysql”已经过时，你应该使用mysqli或PDO。
