tæl antallet af ens værdier
Jeg har følgendene Mysql tabel:
id - han_user - han_id - title - content
01 - user3 - 299 - a title - some text
02 - user5 - 299 - a title - some text
03 - user1 - 299 - a title - some text
04 - user1 - 299 - a title - some text
05 - user1 - 197 - a title - some text
06 - user1 - 543 - a title - some text
07 - user3 - 299 - a title - some text
08 - user1 - 299 - a title - some text
09 - user5 - 123 - a title - some text
10 - user5 - 299 - a title - some text
Jeg vil gerne kunne tælle antallet an han_id for hver han_user
user1:
197 = 1
299 = 3
User3:
299 = 2
user5:
123 = 1
299 = 2
Dette er mit script:
<?
include('config.php');
@session_start();
mysql_connect($mysql['host'],$mysql['user'],$mysql['password']) or die (mysql_error());
mysql_select_db($mysql['db']) or die (mysql_error());
$result = mysql_query("SELECT * FROM `contact_module` ORDER BY `time` DESC");
if(mysql_errno() == 1146) {
mysql_query("CREATE TABLE IF NOT EXISTS `contact_module` (
`id` int(11) NOT NULL auto_increment,
`han_user` varchar(255) NOT NULL default '',
`han_id` varchar(255) NOT NULL default '',
`title` varchar(255) NOT NULL default '',
`time` int(11) NOT NULL default '0',
`content` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM;") or die (mysql_error());
