PHP mail()函數

 

語法

 

    $to：指定郵件的接收者或接收者。 收信者格式:
        user@example.com
        user@example.com, anotheruser@example.com
        User user@example.com
        User user@example.com, User2 anotheruser@example.com
    $subject: 郵件主題。
    $message: 發送的郵件內容
    $additional_headers(可選)：指定附加頭，如From，CC，BCC等。附加頭也用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個字符。

 

PHP郵件範例

 

文件：mailer.php

 

<?php 
   ini_set("sendmail_from", "rh3@dyhms.no-ip.org"); 
   $to = "joke111.y@gmail.com"; //receiver address 
   $subject = "郵件主旨"; 
   $message = "從 localhost 轉 NAT server 發信"; 
   $header = "發信者: rh3@dyhms.no-ip.org\r\n"; 

 

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

 

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

 

如果在運行服務器上運行此代碼，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. 則需在消息標題中提及Content-type text/html。

 

<?php 
   $to = "joke111.y@gmail.com";//change receiver address 
   $subject = "This is subject"; 
   $message = "<h1>This is HTML heading</h1>"; 

 

   $header = "From: rh3@dyhms.no-ip.org\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

 

要發送附件, 則需提及許多標題信息，參示例:

 

<?php 
  $to = "joke111.y@gmail.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 .= "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..."; 
   } 
?>
