代码有2张，和一个sql

1.conn_count.php

< ?php

$host="localhost"; //请在双引号内填写你的mysql数据库主机

$root=""; //请在双引号内填写你的mysql数据库账号

$pw=""; //请在双引号内填写你的mysql数据库密码

$name=""; //请在双引号内填写你的mysql数据库名称

$link=mysql_connect($host,$root,$pw);

mysql_select_db($name,$link);

?>

2.count.php

3.sql

CREATE TABLE `ip` (

`id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,

`ip` VARCHAR( 30 ) NOT NULL ,

`time` DATE NOT NULL

) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci

CREATE TABLE `parameter` (

`id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,

`count` TEXT NOT NULL ,

`today` TEXT NOT NULL ,

`today_date` DATE NOT NULL ,

`time` TIME NOT NULL

) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci

CREATE TABLE `online` (

`id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,

`ip` VARCHAR( 19 ) NOT NULL ,

`onlinetime` TIME NOT NULL

) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci

INSERT INTO `parameter` (

`id` ,

`count` ,

`today` ,

`today_date` ,

`time`

)

VALUES (

NULL , '1', '', '2011-06-21', '14:55:26'

);

sql分别运行 创建各表

4.调用方式
