PHP使用POP3读取邮箱接收邮件的示例代码

直接上代码：

<?php
$array_values['host'] = "host";
$array_values['port'] = 110;
$array_values['user'] = '用户名';
$array_values['password'] = '密码';
$array_values['checkmail'] = 'xxx@xxx.xxx';

ganji_get_test_mail($array_values);

function ganji_get_test_mail($array_values)
{
 $host = $array_values['host'];
 $port = $array_values['port'];
 $user = $array_values['user'];
 $password = $array_values['password'];
 $checkmail = $array_values['checkmail'];
 $msg = '';
 $return_msg = '';
 // ini_set('memory_limit', '80M');
 if (! ($sock = fsockopen(gethostbyname($host), $port, $errno, $errstr))) {
   exit($errno . ': ' . $errstr);
 }

set_socket_blocking($sock, true);

$command = "USER " . $user . "\r\n";
 fwrite($sock, $command);
 $msg = fgets($sock);
 $command = "PASS " . $password . "\r\n";
 fwrite($sock, $command);
 $msg = fgets($sock);

$command = "stat\r\n";
 fwrite($sock, $command);
 $return_msg = fgets($sock);

$msg = fgets($sock);

$command = "LIST\r\n";
 fwrite($sock, $command);
 $all_mails = array();
 while (true) {
   $msg = fgets($sock);
   if (! preg_match('/^\+OK/', $msg) && ! preg_match('/^\./', $msg)) {
     $msg = preg_replace('/\ .*\r\n/', '', $msg);
     array_push($all_mails, $msg);
   }
   if (preg_match('/^\./', $msg))
     break;
 }

// 获取邮件列表
 $ganji_mails = array();
 foreach ($all_mails as $item) {
   fwrite($sock, "TOP $item 0\r\n");
   while (true) {
     $msg = fgets($sock);
     // echo $msg . "<Br><Br>";
     if (preg_match('/^\./', $msg)) {
       array_push($ganji_mails, $item);
       break;
     }
   }
   continue;
 }

$mail_content = '';
 $array_ganji_mails = array();

//逐行遍历
 foreach ($ganji_mails as $item) {
   fwrite($sock, "RETR $item\r\n");
   while (true) {
     $msg = fgets($sock);
     $mail_content .= $msg;
     if (preg_match('/^\./', $msg)) {
       array_push($array_ganji_mails, iconv_mime_decode_headers($mail_content, 0, "UTF-8"));
       $mail_content = '';
       break;
     }
   }
 }

// 直接获取第一封邮件全部信息 9999长度
 fwrite($sock, "RETR 1\r\n");
 $mail_contents = fread($sock, 9999); // 直接获取全部

echo "<br>";
 var_dump($mail_contents);
 echo "<br>";

$command = "QUIT\r\n";
 fwrite($sock, $command);
 $msg = fgets($sock);

return $mail_contents;
}
