PHP 利用Mail

 重點為one_mail函數。利用Mail_mimeDecode類從郵件中提取郵件頭和郵件正文，具體實現如下

代碼如下: <?php  header("content-type:text/html; charset=UTF-8");  /*  * record kid words and insert into database  * user by sending email to publication kid words  *  */  include 'POP3.php';  include 'email_class.php';  include 'Mail_mimeDecode.php';  //include 'include/compatible.php';  include 'include/extend_common.php';  //include '../../htdocs/include/extend_common.php';  define('POST_FROM_EMAIL', 1);  define('DATABASE_CONNECTION_ERROR', 2); //數據庫連接失敗錯誤  define('EMAIL_CONNECTION_ERROR', 3); //郵箱連接失敗錯誤  define('ACCOUNT_ERROR', 4); //郵箱的賬號錯誤  define('SIGN_EMAIL_ERROR', 5); //郵件標記刪除錯誤  define('DELELET_ERROR', 6); //刪除郵件錯誤  define('INSERT_ERROR', 7); //插入數據失敗錯誤    class mail_data {    function mail_data() {  include 'config.php';  $mail_log = fopen("mail_log.txt", "a+");  $conn = @ mysql_connect($db_host, $db_user, $db_password);  if ($conn) {  mysql_select_db('t', $conn);  mysql_query("set names utf8");  $pop3 = new Net_POP3();  //判斷連接是否成功  if ($pop3->connect($host, 110)) {  //判斷登入是否成功  if ($pop3->login($user, $password) === true) {  $list = $pop3->_cmdList();  $sum = $pop3->_cmdStat();    //每次取多少郵件  $step = 2;  $r = 0;  //先對郵箱取$step郵件  for ($n = 0; $n < $sum[0]; $n += $step) {  $t = 0;  $users = array ();  $mail = array ();  $offset = ($sum[0] - $n) < $step ?
