PHP連接MYSQL數(shù)據(jù)庫代碼

<?php

$mysql_server_name='localhost'; //改成自己的mysql數(shù)據(jù)庫服務(wù)器

$mysql_username='root'; //改成自己的mysql數(shù)據(jù)庫用戶名

$mysql_password='12345678'; //改成自己的mysql數(shù)據(jù)庫密碼

$mysql_database='mycounter'; //改成自己的mysql數(shù)據(jù)庫名

$conn=mysql_connect($mysql_server_name,$mysql_username,$mysql_password,$mysql_da tabase);

$sql='CREATE DATABASE mycounter DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci; ';

mysql_query($sql);

$sql='CREATE TABLE `counter` (`id` INT(255) UNSIGNED NOT NULL AUTO_INCREMENT ,`count` INT(255) UNSIGNED NOT NULL DEFAULT 0,PRIMARY KEY ( `id` ) ) TYPE = innodb;';

mysql_select_db($mysql_database,$conn);

$result=mysql_query($sql);

//echo $sql;

mysql_close($conn);

echo "Hello!數(shù)據(jù)庫mycounter已經(jīng)成功建立!";

PHP連接ACCESS數(shù)據(jù)庫代碼方法

<?

$conn = new com("ADODB.Connection");

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

$conn->Open($connstr);

$rs = new com("ADODB.RecordSet");

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

while(! $rs->eof) {

$f = $rs->Fields(1);

echo $f->value;

$rs->MoveNext();

}

?>

PHP連接MS SQL數(shù)據(jù)庫代碼方法

1.安裝SQL服務(wù)器并添加PHP的MSSQL擴展

2.使用以下代碼連接并測試

<?php

$myServer = localhost; //主機

$myUser = sa; //用戶名

$myPass = password; //密碼

$myDB = Northwind; //MSSQL庫名

$s = @mssql_connect($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>;

}

?>

PHP連接Oracle數(shù)據(jù)庫

PHP提供了兩套函數(shù)與Oracle連接,分別是ORA_和OCI函數(shù)。其中ORA_函數(shù)略顯陳舊。OCI 函數(shù)更新?lián)f更好一些。兩者的使用語法幾乎相差無幾。你的PHP安裝選項應(yīng)該可以支持兩者的使用。

連接

< ? if ($conn=Ora_Logon("user@TNSNAME","password"))

{ echo "SUCCESS ! Connected to database ";

}else

{echo "Failed :-( Could not connect to database ";}

Ora_Logoff($conn);

phpinfo();

?>

以上代碼使用TNSNAME(在你的tnsnames.ora文件中指明)定義的Oracle數(shù)據(jù)庫名稱、用戶名稱和密碼連接數(shù)據(jù)庫。在成功連接的基礎(chǔ)上,ora_logon函數(shù)返回一個非零的連接ID 并儲存在變量$conn中。
