php常用的幾種發送郵件代碼

下面這些發送電子郵件代碼，用了一個imap與php教程自帶的mail函數來實例，非常方法的，還有一種就是協力廠商外掛程式哦，phpmailer來發送郵件。

<?php
連接 IMAP 伺服器連結，IMAP 的埠為 143。
$mbox = imap_open("{localhost:143}INBOX","user_id","password");
連接POP3 伺服器連結，POP3 的埠為 110。
$mbox = imap_open("{localhost/pop3:110}INBOX","user_id","password");
連接NNTP 伺服器連結，NNTP 的埠為 119。
$nntp = imap_open("{localhost/nntp:119}comp.test","","");
?>

<?php
連接IMAP伺服器
$mbox = imap_open("{imap.example.org}", "username", "password", OP_HALFOPEN)
or die("連接失敗: " . imap_last_error());
$list = imap_getmailboxes($mbox, "{imap.example.org}", "*");
if (is_array($list)) {
foreach ($list as $key => $val) {
echo "($key) ";
echo imap_utf7_decode($val->name) . ",";
echo "'" . $val->delimiter . "',";
echo $val->attributes . "<br />n";
}
} else {
echo "imap_getmailboxes 失敗: " . imap_last_error() . "n";
}
關閉imap連接
imap_close($mbox);
?>

<?php
mail( "163@163.com", "歡迎你", "hello,你好! " );
?>

<?php
//定義邊界線
$boundary = uniqid( "" );
//生成郵件頭
$header = "From: $fromnContent-type: multipart/mixed;
boundary="$boundary"nX-Mailer:PHPnX-Priority:3";
//獲取附件檔的MIME類型
$mimetype = mime_content_type('test.zip')
//獲取附件檔的名字
$attach = 'test.zip'
//對附件檔 進行編碼和切分
$fp = fopen($attach, "r");
$content = fread($fp, filesize($attach));
$content = chunk_split( base64_en code($content) );
//生成郵件主體
$body ="
--$boundary
Content-type: text/plain; charset=iso-8859-1
Content-transfer-encoding: 8bit
$message
--$boundary
Content-Type: $mimeType; name=$filename
Content-Disposition: attachment; filename=$filename
Content-Transfer-Encoding: base64
$content
--$boundary--";
//發送郵件
mail( $to, $ subject, $body, $header );
?>

<?php
$mbox=imap_open("{localhost:143}INBOX","myid","mypw");
$message=imap_body($mbox,1);
imap_ close($mbox);
echo$message;
?>
