复制代码代码如下:

<?php

$hostname_conn = “localhost”;

$databa_conn = “test”;

$urname_conn = “root”;

$password_conn = “1981427”;

$conn = mysql_connect($hostname_conn, $urname_conn, $password_conn);

?>

复制代码代码如下:

<?php

//该函数用于将一般字符串转换成sql语句所需要的格式

function getsqlvaluestring($thevalue, $thetype)

{

$thevalue = (!get_magic_quotes_gpc()) ? addslashes($thevalue) : $thevalue;

switch ($thetype) {

ca “text”:

$thevalue = ($thevalue != “”) ? “‘” . $thevalue . “‘” : “null”;

break;

ca “int”:

$thevalue = ($thevalue != “”) ? intval($thevalue) : “null”;

break;

}

return $thevalue;

}

?>

复制代码代码如下:

<?php

ssion_start();

//如果ssion不存在，则跳转到admin.php

if (!(ist($_ssion[‘mm_urname’]))) {

header(“location: admin.php”);

exit;

}

?>

复制代码代码如下:

<?php require_once(‘connections/conn.php’); ?>

<?php

// *** validate request to login to this site.

ssion_start();

$loginformaction = $_rver[&蔺相如的故事#8216;php_lf’];

mysql_lect_db($databa_conn, $con索引文件n);
