PHP發送電子郵件（Email）

PHP mail()函數用於在PHP中發送電子郵件。 您可以使用PHP mail()函數來發送短信，HTML消息和附件與消息。

PHP mail()函數

語法

• $to：指定郵件的接收者或接收者。 接收器必須指定以下格式之一。
  • user@example.com
  • user@example.com, anotheruser@example.com
  • User user@example.com
  • User user@example.com, User2 anotheruser@example.com
• $subject: 代表郵件的主題。
• $message: 表示要發送的郵件的消息。
• $additional_headers(可選)：指定附加頭，如From，CC，BCC等。額外的附加頭也應該用CRLF(\r\n)分隔。

注意：消息的每一行應使用CRLF(\r\n)分隔，並且行不應大於70個字元。

PHP郵件示例

檔：mailer.php

<?php
   ini_set("sendmail_from", "maxsujaiswal@xuhuhu.com");
   $to = "maxsujaiswal1987@gmail.com";//change receiver address
   $subject = "This is subject";
   $message = "This is simple text message.";
   $header = "From:maxsujaiswal@xuhuhu.com \r\n";

   $result = mail ($to,$subject,$message,$header);

   if( $result == true ){
      echo "Message sent successfully...";
   }else{
      echo "Sorry, unable to send mail...";
   }
?>

如果在運行伺服器上運行此代碼，它將向指定的接收方發送電子郵件。

PHP郵件：發送HTML消息

要發送HTML消息，您需要在消息標題中提及Content-type text/html。

<?php
   $to = "abc@example.com";//change receiver address
   $subject = "This is subject";
   $message = "<h1>This is HTML heading</h1>";

   $header = "From:xyz@example.com \r\n";
   $header .= "MIME-Version: 1.0 \r\n";
   $header .= "Content-type: text/html;charset=UTF-8 \r\n";

   $result = mail ($to,$subject,$message,$header);

   if( $result == true ){
      echo "Message sent successfully...";
   }else{
      echo "Sorry, unable to send mail...";
   }
?>

PHP郵件：使用附件發送郵件

要使用附件發送消息，您需要提及許多標題資訊，在下面給出的示例中使用。

<?php
  $to = "abc@example.com";
  $subject = "This is subject";
  $message = "This is a text message.";
  # Open a file
  $file = fopen("/tmp/test.txt", "r" );//change your file location
  if( $file == false )
  {
     echo "Error in opening file";
     exit();
  }
  # Read the file into a variable
  $size = filesize("/tmp/test.txt");
  $content = fread( $file, $size);

  # encode the data for safe transit
  # and insert \r\n after every 76 chars.
  $encoded_content = chunk_split( base64_encode($content));

  # Get a random 32 bit number using time() as seed.
  $num = md5( time() );

  # Define the main headers.
  $header = "From:xyz@example.com\r\n";
  $header .= "MIME-Version: 1.0\r\n";
  $header .= "Content-Type: multipart/mixed; ";
  $header .= "boundary=$num\r\n";
  $header .= "--$num\r\n";

  # Define the message section
  $header .= "Content-Type: text/plain\r\n";
  $header .= "Content-Transfer-Encoding:8bit\r\n\n";
  $header .= "$message\r\n";
  $header .= "--$num\r\n";

  # Define the attachment section
  $header .= "Content-Type:  multipart/mixed; ";
  $header .= "name=\"test.txt\"\r\n";
  $header .= "Content-Transfer-Encoding:base64\r\n";
  $header .= "Content-Disposition:attachment; ";
  $header .= "filename=\"test.txt\"\r\n\n";
  $header .= "$encoded_content\r\n";
  $header .= "--$num--";

  # Send email now
  $result = mail ( $to, $subject, "", $header );
  if( $result == true ){
      echo "Message sent successfully...";
   }else{
      echo "Sorry, unable to send mail...";
   }
?>
