以SQL为例。使用PHP MySQL 函数可以编辑数据库。
mysql_connect() 函数打开MySQL 连接。举例
?php
$con = mysql_connect("localhost","mysql_user","mysql_pwd");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}// 一些代码...mysql_close($con);
?
mysql_connect()三个参数分别是服务器名，连接账号，连接密码。
连接之后，可以使用mysql_select_db()设置要处理的数据库，后面则是用数据库语句处理数据。SQL语法简介网页链接
几种常用PHP连接数据库的代码示例
PHP连接数据库之PHP连接MYSQL数据库代码
?php $mysql_server_name= localhost ; //改成自己的mysql数据库服务器 $mysql_username= root ; //改成自己的mysql数据库用户名 $mysql_password= ; //改成自己的mysql数据库密码 $mysql_database= mycounter ; //改成自己的mysql数据库名 $conn=mysql_connect($mysql_server_name $mysql_username $mysql_password $mysql_database); $sql= CREATE DATABASE mycounter DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci; ; mysql_query($sql); $sql= CREATE TABLE `counter` (`id` INT( ) UNSIGNED NOT NULL AUTO_INCREMENT `count` INT( ) UNSIGNED NOT NULL DEFAULT PRIMARY KEY ( `id` ) ) TYPE = innodb; ; mysql_select_db($mysql_database $conn); $result=mysql_query($sql); //echo $sql; mysql_close($conn); echo "Hello!数据库mycounter已经成功建立！"; ?
PHP连接数据库之PHP连接ACCESS数据库代码方法
? $conn = new ("ADODB Connection"); $connstr = "DRIVER={Microsoft Access Driver (* mdb)}; DBQ=" realpath("data/db mdb"); $conn Open($connstr); $rs = new ("ADODB RecordSet"); $rs Open("select * from szd_t" $conn ); while(! $rs eof) { $f = $rs Fields( ); echo $f value; $rs MoveNext(); } ?
PHP连接数据库之PHP连接MS SQL数据库代码方法
安装SQL服务器并添加PHP的MSSQL扩展
使用以下代码连接并测试
?php $myServer = localhost; //主机 $myUser = sa; //用户名 $myPass = password; //密码 $myDB = Northwind; //MSSQL库名 $s = @mssql_connect($myServer $myUser $myPass) or die(Couldnt connect to SQL Server on $myServer); $d = @mssql_select_db($myDB $s) or die(Couldnt open database $myDB); $query = SELECT TitleOfCourtesy+ +FirstName+ +LastName AS Employee ; $query = FROM Employees ; $query = WHERECountry=USA AND Left(HomePhone ) = ( ); $result = mssql_query($query); $numRows = mssql_num_rows($result); echo h $numRows Row ($numRows == ? : s) Returned / h ; while($row = mssql_fetch_array($result)) { echo li $row[Employee] /li; } ?
PHP连接数据库之PHP连接Oracle数据库
PHP提供了两套函数与Oracle连接 分别是ORA_和OCI函数 其中ORA_函数略显陈旧 OCI函数更新据说更好一些 两者的使用语法几乎相差无几 你的PHP安装选项应该可以支持两者的使用
? if ($conn=Ora_Logon("user@TNSNAME" "password")) { echo "SUCCESS ! Connected to databasen"; }else {echo "Failed : ( Could not connect to databasen";} Ora_Logoff($conn); phpinfo(); ? lishixinzhi/Article/program/PHP/201405/30761
php连接mysql,如何用php代码将数据写入数据库?》??
连接：mysql_connect("主机","用户","密码");
mysql_select_db("数据库名");
写入数据：mysql_query("insert
into
表名
(字段1，字段2)
values
("数据1","数据2")");
你的问题太含糊，只能给你这个答复，不明白再追问。
