PHP与各种数据库连接代码整理

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='888888';//改成自己的MysqL数据库密码

$MysqL_database='studyPHP';//改成自己的MysqL数据库名

$conn=MysqL_connect($MysqL_server_name,$MysqL_username,$MysqL_password,$MysqL_database); 

//以下为开始建立数据库及表，如果你已经有请略过此步

$sql='create database studyPHP default character set gbk collate gbk_chinese_ci; 

'; 

MysqL_query($sql); 

$sql='create table `lwpcms_news` (`id` int(255) unsigned not null auto_increment,`title` int(255) unsigned not null default 0,`content` text,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studyPHP已经成功建立！"; 

?>

PHP连接ACCESS数据库代码

<?

$conn = new com("ADODB.Connection"); 

$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("db1.mdb"); 

$conn->Open($connstr); 

$rs = new com("ADODB.RecordSet"); 

$rs->Open("select * from News",$conn,1,1); 

while(! $rs->eof) { 

$f = $rs->Fields(1); 

echo '<br />';

echo $f->value; 

$rs->MoveNext(); 

} 

?>

PHP连接MS sql数据库代码

1.安装sql服务器并添加PHP的MSsql扩展

2.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 .= WHERE Country=USA AND Left(HomePhone,5) = (206); 

$result = mssql_query($query); 

$numRows = mssql_num_rows($result); 

echo <h1> . $numRows . Row . ($numRows == 1 ? : s) . Returned </h1>; 

while($row = mssql_fetch_array($result)) 

{ 

echo <li> . $row[Employee] . </li>; 

} 

?>
