b>数据库链接 10. PHP最大的特色就是操作数据库的能力特别的强大,PHP提供对多种数据库的支持。   通过PHP你可以轻松的连接到数据库,请求数据并将其显示在你的web站点中,甚至修改数据库中的数据。在这一节里我们主要以在互联网上跟PHP一起使用得最多的MySQL数据库为例,介绍一下相关的MySQL数据库的操作函数以及数据库的基本操作等方面的知识。 在MySQL数据库中,我们用来连接数据库的函数有两个,它们分别为: integer mysql_connect(string host,string user,string password); integer mysql_pconnect(string host,string user,string password); mysql_connect函数和mysql_pconnect函数都是对指定主机上MySQL数据库的连接,如果该数据库位于一个不同的端口,则可以在主机名后加上冒号和端口号。函数的参数也可以缺省不填,如果不填参数,默认的主机名是“localhost”,用户名为数据库管理员,默认值为“root”,密码为空。与数据库连接成功之后,这两个函数都可以返回一个连接号,如果连接失败,则返回一个false值。让我们来看看下面几句语句: $#@60;? $db=mysql_connect("localhost","user","password"); mysql_select_db("mydb",$db); ?$#@62; 注释: $db=mysql_connect("localhost","user","password"); 我们将mysql的链接参数,包括主机名、用户名和密码作为mysql_connect()的参数,同时得到返回值为$db,这样,在下面的语句中,我们就可以将变量$db作为一个连接mysql数据库的连接号来使用。 mysql_select_db("mydb",$db); 将PHP程序链接到mydb数据库中,这样程序与数据库的链接就完成了。 10.1 一个简易的数据库留言簿   在完成数据库的链接之后,我们就可以对数据库进行一系列的操作。下面是一个简易的数据库留言簿程序(guestbook.php3):   我假设你机子上的MySQL数据库以及管理MYSQL数据库的工具 Phpmyadmin_2. 0.5都已经安装完成,并且可以正常工作。 我们要做的第一件事情是创建一个留言数据库,假定名字为: mydb。 1、启动浏览器,打开Phpmyadmin_2. 0.5 的管理WEB界面。 2、在“Create new database”文本框内输入数据库名称mydb,然后按create按键。   下一步,我们要在该留言数据库下创建一个数据表,假定名字为: guestboo 创建该数据表的命令如下所示: CREATE TABLE guestbook (ID INT NOT NULL AUTO_INCREMENT, name CHAR(250), email CHAR(250), job CHAR(250), comments BLOB, PRIMARY KEY(ID)); 最后,将下面的留言簿程序挎贝到你机子的可写目录下面,并保存成guestbook.php3文件。就这么简单,你已经有了自己的留言簿了。 10.2 留言簿程序(guestbook.php3): $#@60;?php /* $host : your MySQL-host, usually localhost */ /* $user : your MYSQL-username */ /* $password : your MySQL-password */ /* $database : your MySQL-database */ /* $table : your MySQL-table */ /* $page_title : the title of your guestbook-pages */ /* $admin_mail : email-address of the administrator to send the new entries to */ /* $admin_name : the name of the administrator */ /* $html_mail : say yes if your mail-agent can handle HTML-mail, else say no */ $host = "localhost"; $user = ""; $password = ""; $database = "mydb"; $table = "guestbook"; $page_title = "pert guestbook"; $admin_mail = "pert@21cn.com"; $admin_name = "Webmaster"; $html_mail = "no"; ?$#@62; $#@60;HTML$#@62; $#@60;HEAD$#@62; $#@60;TITLE$#@62;$#@60;?php echo $page_title; ?$#@62;$#@60;/TITLE$#@62; $#@60;/HEAD$#@62; $#@60;BODY BGCOLOR="#FFFFFF" LINK="#000000"$#@62; $#@60;FONT FACE="Verdana" SIZE="-2"$#@62; $#@60;?
