实例说明制作一个php+mysql留言本
代码如下:

  1. <?php
  2. $hostname_conn = "localhost";
  3. $database_conn = "test";
  4. $username_conn = "root";
  5. $password_conn = "1981427";
  6. $conn = mysql_connect($hostname_conn, $username_conn, $password_conn);
  7. ?>
复制代码

代码如下:


  2. <?php
  3. //该函数用于将一般字符串转换成SQL语句所需要的格式
  4. function GetSQLValueString($theValue, $theType)
  5. {
  6. $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;
  7. switch ($theType) {
  8. case "text":
  9. $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
  10. break;
  11. case "int":
  12. $theValue = ($theValue != "") ? intval($theValue) : "NULL";
  13. break;
  14. }
  15. return $theValue;
  16. }
  17. ?>
复制代码

代码如下:


  2. <?php
  3. session_start();
  4. //如果Session不存在，则跳转到Admin.php
  5. if (!(isset($_SESSION['MM_Username']))) {
  6. header("Location: admin.php");
  7. exit;
  8. }
  9. ?>
复制代码

代码如下:
