PHP从txt列表发送邮件时延迟

我有这个脚本从emails.txt列表发送邮件，并且工作正常，但是有没有办法延迟从列表中发送邮件？任何帮助表示赞赏，谢谢！PHP从txt列表发送邮件时延迟

这是PHP发送脚本：

if($_POST) 
{ 

    $recipient_email = ''; 

     $name = filter_var($_POST["name"], FILTER_SANITIZE_STRING); 
     $from_email = filter_var($_POST["sender_email"], FILTER_SANITIZE_STRING); 
    $bcc = filter_var($_POST["bcc"], FILTER_SANITIZE_STRING); 
    $reply_to_email = filter_var($_POST["email"], FILTER_SANITIZE_STRING); 
    $subject  = filter_var($_POST["subject"], FILTER_SANITIZE_STRING); 
    $message  = filter_var($_POST["message"], FILTER_SANITIZE_STRING); 
     $mesaj  = filter_var($_POST["message"], FILTER_SANITIZE_STRING); 

     //Get uploaded file data 
    $file_tmp_name = $_FILES['my_file']['tmp_name']; 
    $file_name  = $_FILES['my_file']['name']; 
    $file_size  = $_FILES['my_file']['size']; 
    $file_type  = $_FILES['my_file']['type']; 
    $file_error  = $_FILES['my_file']['error']; 

     $lista = $_FILES['lista']['tmp_name']; 

    if($file_error > 0) 
    { 
     die('Upload error or No files uploaded'); 
    } 

     $handle = fopen($file_tmp_name,'rb'); 

     // Now read the file content into a variable 
     $content = fread($file,filesize($file_tmp_name)); 

     // close the file 
     fclose($handle); 

     // Now we need to encode it and split it into acceptable length lines 
     $encoded_content = chunk_split(base64_encode(file_get_contents($file_tmp_name))); 

      $uid = md5(date('r', time())); 

     //header 
     $headers = "From: ".$name." <".$from_email.">\r\n"; 
     $headers .= "Bcc: $bcc\r\n"; 
     $headers .= "Reply-To: ".$reply_to_email."\r\n"; 
     $headers .= "MIME-Version: 1.0\r\n"; 
     $headers .= "Content-Type: multipart/mixed; boundary=\"PHP-mixed-".$uid."\"\r\n\r\n"; 

$message = "--PHP-mixed-$uid\r\n"."Content-Type: multipart/alternative; boundary=\"PHP-alt-$uid\"\r\n\r\n"; 
$message .= "--PHP-alt-$uid\r\n"."Content-Type: text/plain; charset=\"iso-8859-1\"\r\n"."Content-Transfer-Encoding: 7bit\r\n\r\n"; 

//Insert the html message. 
$message .= $mesaj; 
$message .="\r\n\r\n--PHP-alt-$uid--\r\n\r\n"; 

//include attachment 
$message .= "--PHP-mixed-$uid\r\n"."Content-Type: $file_type; name=\"$file_name\"\r\n"."Content-Transfer-Encoding: base64\r\n"."Content-Disposition: attachment\r\n\r\n"; 
$message .= $encoded_content; 
$message .="Content-Transfer-Encoding: base64\r\n"; 
$message .="X-Attachment-Id: ".rand(1000,99999)."\r\n\r\n"; 
$message .= "/r/n--PHP-mixed-$uid--"; 

    $list = fopen($lista, "r"); 

    if ($list) { 
     while (($line = fgets($list)) !== false) { 

      if (!mail($line, $subject, $message, $headers)) 
      { 
       echo "Eroare! Nu am putut trimite mailurile."; 
      } 
      else 
      { 

       echo "Mailurile au fost trimise!"; 
      } 


      } 
fclose($list); 
     } 
}

HTML表单字段：

<form enctype="multipart/form-data" method="POST" action=""> 
<label>Name <input type="text" name="sender_name" /> </label> 
</br><label>Mail <input type="email" name="sender_email" /> </label> 
<label>Bcc <input type="text" name="bcc" /> </label> 
</br><label>Subject <input type="text" name="subject" /> </label> 
</br> <label>Message <textarea name="message"></textarea> </label> 
</br><label>attachment <input type="file" name="my_file" /></label> 
</br><label>Mail list <input type="file" name="lista" /></label> 

</br> <label><input type="submit" name="button" value="Fire :)" /></label> 
</form>

使用'sleep（）'函数暂停脚本。 – Barmar

例如，您可以使用睡眠（3）将其暂停三秒钟。然后继续循环 – ATechGuy

使用sleep（）添加的任何延迟也会延迟对用户的响应时间。我注意到一切都包含if（$ _ POST）。用户是否通过在线表单发布到此脚本？您是否想延迟将电子邮件发送到更晚的预定时间？ –

可以使用睡眠（）命令暂停它

while (($line = fgets($list)) !== false) { 

     if (!mail($line, $subject, $message, $headers)) 
     { 
      echo "Eroare! Nu am putut trimite mailurile."; 
     } 
     else 
     { 

      echo "Mailurile au fost trimise!"; 
     } 

     sleep(3) 
     }

例如
