我500 Internal Server在各种共享主机上的基于PHP/MySQL的站点上遇到了随机错误.我在共享的Linux服务器上使用PHP 5.2.17到CGI/FastCGI.当我查看日志时,我看到了这个:
[error] [client 75.71.176.224] (104)Connection reset by peer: FastCGI: comm with server "/dev/shm/blackmou-php.fcgi" aborted: read failed, referer: ...
[error] [client 75.71.176.224] FastCGI: incomplete headers (0 bytes) received from server "/dev/shm/blackmou-php.fcgi", referer: ...

谁知道如何解决这个问题？
如果我在网页上两次使用Google Analytics"综合浏览量",Google会将网页浏览计算一次或两次吗？
这是一页上的代码.
第一次"综合浏览"电话
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-XXXXX-Y', 'auto');
ga('send', 'pageview');
</script>
次要的"综合浏览"电话
<script>
ga('set', 'page', '/mysite/custom/page');
ga('send', 'pageview');
</script>
谢谢你的帮助!
我想提取具有相同用户名的特定行的所有唯一 ID，然后将每个结果显示为一行。
例如...
这是我的表：
+----+------+
| id | name |
+----+------+
| 1 | Joe |
| 2 | Amy |
| 3 | Joe |
| 4 | Amy |
| 5 | Joe |
| 6 | Amy |
+----+------+
这是我想要的结果：
+------+-------+
| name | ids |
+------+-------+
| Joe | 1,3,5 |
| Amy | 2,4,6 |
+------+-------+
如何在 MySQL 中提取此结果？
