本篇文章是对用PHP实现邮件群发的代码进行了详细的分析介绍,需要的朋友参考下
// 请求 PHPmailer类 文件
require_once("class.phpmailer.php");
//发送Email函数
function smtp_mail ( $sendto_email, $subject, $body, $extra_hdrs, $user_name) {
$mail = new PHPMailer();
$mail->IsSMTP(); // send via SMTP
$mail->Host = "smtp.163.com"; // SMTP servers
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username = "jessiejl"; // SMTP username 注意:普通邮件认证不需要加 @域名
$mail->Password = "1983106"; // SMTP password
$mail->From = ""; // 发件人邮箱
$mail->FromName = "WWW.NIUTW.COM"; // 发件人 ,比如 唯美搭配网
$mail->CharSet = "GB2312"; // 这里指定字符集!
$mail->Encoding = "base64";
$mail->AddAddress($sendto_email,$user_name); // 收件人邮箱和姓名
$mail->AddReplyTo("","Web之家");
//$mail->WordWrap = 50; // set word wrap
//$mail->AddAttachment("/var/tmp/file.tar.gz"); // attachment 附件1
//$mail->AddAttachment("/tmp/image.jpg", "new.jpg"); //附件2
$mail->IsHTML(true); // send as HTML
$mail->Subject = $subject;
// 邮件内容 可以直接发送html文件
$mail->Body = <<
EOT;
$mail->AltBody ="text/html";
if($mail->Send())
{
info_write("ok.txt","$user_name 发送成功");
}
else {
info_write("falied.txt","$user_name 失败,错误信息$mail->ErrorInfo");
}
}
// 发送Email函数结束
// 写入发送结果函数,错误日志记录
function info_write($filename,$info_log)
{
$info.= $info_log;
$info.="\r\n";
$fp = fopen ($filename,a);
fwrite($fp,$info);
fclose($fp);
}
//定时跳转页面 函数 其中 1000是时间,1秒, 您可以自定义
function redirect($url)
{
echo "<script> <br> function redirect() <br> { <br> window.location.replace('$url'); <br> } <br> window.setTimeout('redirect();', 15000); <br> </script>";
}
//读取文本 邮件地址 您也可以读 数据库
$filename = "email.txt";
$fp = fopen($filename,"r");
$contents = fread($fp,filesize($filename));
$list_email=explode("\r\n",$contents);
$len=count($list_email);
fclose($fp);
// 参数说明(发送到, 邮件主题, 邮件内容, 附加信息, 用户名)
$i = $_GET['action'];
$i++;
if ($i<$len)
{
$rs=explode("@",$list_email[$i]);
$user_name = $rs['0'];
echo "正在发送第{$i}封({$list_email[$i]})邮件......{$user_name}";
smtp_mail($list_email[$i], 'Treasurery Online 周刊第十二期', $body, 'http://www.yem120.com/', $user_name);
redirect("?action=$i");
}
else {
echo "邮件全部发送完毕";
exit;
}
?>
小思维:
上面的读取文章email.txt,也可以直接是qq号码,每行一个号码,然后用fget()读取每行qq号码,最后在加上qq邮箱后缀 @qq.com即可

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
