幾種常用PHP連接數(shù)據(jù)庫的代碼示例

PHP連接數(shù)據(jù)庫之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_database);???

$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連接數(shù)據(jù)庫之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();???

}???

用PHP做多項(xiàng)選擇題,數(shù)據(jù)庫怎么設(shè)計(jì), 代碼怎么寫....

數(shù)據(jù)庫的設(shè)計(jì)本人認(rèn)為可以這樣，提交表單應(yīng)該再設(shè)置一個(gè)隱藏域，儲存題目ID，例如

" name="an_id"

處理頁面可以使用將獲取到的答案數(shù)組

$_POST['itm']進(jìn)行遍歷，用循環(huán)$value查找question，可以使用函數(shù)strpos()，該函數(shù)如果返回?cái)?shù)字，則是正確答案，如果返回false，則是錯(cuò)誤答案

if(isset($_POST['an_id'])){

$an_id = $_POST['an_id'];

$qus_sql = "select `question` from `vote_answer` where id = $an_id";

$query = mysql_query($qus_sql);

while($row = mysql_fetch_row($query)){

$question = $row[0];

}

$user_question = $_POST['itm'];

foreach($user_question as $value){

if(strpos($question,$value){

echo '正確答案';

}else{

echo '錯(cuò)誤答案';

}

}

}全手寫代碼，有錯(cuò)誤請百度HI我！
