imap_open()的奇怪问题

<?php
  session_start();
  $hostname="{".$_POST[hostname].":110/pop3}";
  $username=$_POST[username];
  $userpwd=$_POST[userpwd];
  if(!$mbox=@imap_open("$hostname","$username","$userpwd")){
     echo "<script>alert('登录失败!');history.back();</script>";
  
  }else{
  session_register("host");
  session_register("user");
  session_register("pwd");
  $_SESSION[host]=$hostname;
  $_SESSION[user]=$username;
  $_SESSION[pwd]=$userpwd;
  
    echo "<script>window.location.href='indexs.php?lmbs=登录';</script>"; }
?>
文件执行后,显示空白页,无法转到页面:"indexs.php?lmbs=登录".
我如果改成
<?php
  session_start();
  $hostname="{".$_POST[hostname].":110/pop3}";
  $username=$_POST[username];
  $userpwd=$_POST[userpwd];
  session_register("host");
  session_register("user");
  session_register("pwd");
  $_SESSION[host]=$hostname;
  $_SESSION[user]=$username;
  $_SESSION[pwd]=$userpwd;
  
    echo "<script>window.location.href='indexs.php?lmbs=登录';</script>"; 
?>
即不使用"  if(!$mbox=@imap_open("$hostname","$username","$userpwd")){
     echo "<script>alert('登录失败!');history.back();</script>";
  
  }"语句,
则可正常转到页面:"indexs.php?lmbs=登录",并由:"indexs.php?lmbs=登录"跳转到"lookmail.php"."lookmail.php"文件里也有"if(!$mbox=@imap_open("$hostname","$username","$userpwd")){
   echo "<script>alert('登录超时，请重新登录!');history.back();</script>";
   exit;
}"语句,且能正常执行.
请问哪里出问题了?
以下是indexs.php文件中的关联部分:
switch($lmbs){
     case "连接短信" :
     include "short_note.php";     break;
 case "连接邮件":    
         include "mail.php";
     break;
 case "登录":    
         include "lookmail.php";
     break;
以下是"lookmail.php"文件:
<?php session_start();
$hostname=$_SESSION[host];
$username=$_SESSION[user];
$userpwd=$_SESSION[pwd];
if(!$mbox=@imap_open("$hostname","$username","$userpwd")){
   echo "<script>alert('登录超时，请重新登录!');history.back();</script>";
   exit;
}
?>

解决方案 »

  1.   

    再看了一下原文件,"lookmail.php"文件中使用"if(!$mbox=@imap_open("$hostname","$username","$userpwd")){ 
      echo " <script>alert('登录超时，请重新登录!');history.back(); </script>"; 
      exit; 
    } "页面也有问题.那应该是$mbox=@imap_open("$hostname","$username","$userpwd")执行有问题.
      

  2.   

    php.ini文件";extension-=php_imap.dll"前的";"我已去掉(文件夹php及windows内).POP3服务的域为mymail.com,邮箱名为master,密码为"m88299gh".测试文件如下:
    <?php 
    if(!$mbox =@imap_open("{10.0.0.208:110/pop3}","[email protected]","m88299gh"))
    { 
    echo "登入失败"; 
    }else{ 
    echo "登入成功"; 
    } 
    ?>
    问题依旧.
      

  3.   

    <?php 
    if(!$mbox =@imap_open("{10.0.0.208:110/pop3}INBOX","[email protected]","m88299gh")) 
    { 
    echo "登入失败"; 
    }else{ 
    echo "登入成功"; 
    } 
    ?> 
    问题依旧
      

  4.   

    这样行不行？
    <?php
    $mbox =@imap_open("{10.0.0.208:110/pop3}INBOX","[email protected]","m88299gh")
    if($mbox) 
    { 
        echo "登入成功";  
    }else{ 
        echo "登入失败";
    } 
    ?>
