如何阅读gmail imap邮件内容

Question

<?php

$stuff = fsockopen('ssl://imap.gmail.com',993);
$reply = fgets($stuff,4096);
echo 'connection: '.$reply.'<br/>';

$request = fputs($stuff,"a1 LOGIN ozgununlu91@gmail.com password\r\n");
$receive = fgets($stuff, 4096);

echo 'login: '.$receive.'<br/>';
$request = fputs($stuff,"a2 LIST '' '*'\r\n");
$response= fgets($stuff, 1024);
echo $response . "<br />";

$request = fputs($stuff,"a3 EXAMINE INBOX\r\n");
$response = '';
$end_of_response = false;
while(!$end_of_response){
$response.= fgets($stuff, 1024);
if(preg_match("/a3 (OK|NO|BAD)/", $response, $responsecode))
 $end_of_response = true;
}
print_r( $response);
echo "<br />";
$request = fputs($stuff, "a4 FETCH 1 BODY[]\r\n");
$response = fgets($stuff, 1024);
echo $response. "<br />";

?>

输出：

connection: * OK Gimap ready for requests from 95.9.132.93 n45if17443282eef.165

我在这个网站上使用了相同的命令; http://www.anta.net/misc/telnet-troubleshooting/imap.shtml

但在（* 1 FETCH（BODY [] {7098}）此行后，我看不到我的邮件内容。

注意：我不想使用imap_list命令，我应该这样做。
