How to use PHP to send mail _php tutorials

PHP's small program for sending mail is simple, but there are a few things to keep in mind. First on the code:

!--? php $to = "gonnsai@163.com"; $user = "Gonn"; $date = Date ("Y year M D Day"); $headers = ' mime-version:1.0 '. "RN"; $headers. = ' content-type:text/html; Charset=utf-8 '. "RN"; $headers. = "To: $to RN"; $headers. = "Cc:252211974@qq.com rn"; $headers. = ' from:gonnsai@163.com '.    "RN";  $subject = "Zhuhai Life Circle"; $subject = "=? UTF-8? B? ". Base64_encode ($subject). "?     ="; $content = ' Dear '. " $user ". ' ：'.'  
 ';  $content. = ' 
 '; $content. = "Thank you for registering in Zhuhai Life Circle, the Wonderful Life starts from Zhuhai Life circle!" ".'      
 '; $content. = "In Zhuhai Life Circle, you can:".  
 '; $content. = "Check the business situation in Zhuhai, convenient for you to live and play." ".'  
 '; $content. = "Learn more about the recent events in Zhuhai to enrich your life. ".'  
 '; $content. = "Browse news hotspots and expand your knowledge. ".'  
 ';  $content. = ' 
 '; $content. = "Zhuhai Life Circle--to build Zhuhai's largest merchant database and constantly strive. ".' Www.zhuhailife.net '. '  
 '; $content. = ' 
 '; $content. = "Zhuhai Life Circle Team". 
 '; $content. = "$date". '      
 ';  $result = Mail ($to, $subject, $content, $headers); if ($result) {echo ' message sent successfully! ';}? > 

There are a few places to be aware of. If the above code is not $subject = "=? UTF-8? B? ". Base64_encode ($subject). "? ="; In this sentence, you will find that the title of the message is garbled, and the message body is correct. The message header needs to be preceded by the function Base64_encode (), which is to encode the data using MIME base64. The title string is pre-encoded type such as: =? UTF-8? B?.

There is also the type of message set to $headers = ' mime-version:1.0 '. "RN";.

Explanation of the wiki: Multipurpose Internet Mail Extensions (mime,multipurpose) is an Internet standard that expands e-mail standards to support non-ASCII characters, mail messages in a variety of formats, such as binary format attachments. This standard is defined in RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049, and so on. RFC 2822, which is a transition from RFC 822, stipulates that e-mail standards do not allow the use of characters other than the 7-bit ASCII character set in mail messages. Because of this, some non-English character messages and binary files, images, sounds and other non-text messages cannot be transmitted in e-mail. MIME defines a symbolic method for representing a wide variety of data types. In addition, a MIME framework is used in the HTTP protocol used in the World Wide Web.

MIME is implemented by standardizing the fields of the header of an e-mail message, and the additional areas of these headers describe the content and organization of the new message type.

$headers. = ' content-type:text/html; Charset=utf-8 '. "RN"; When the type is HTML, the message body can use the HTML tag.

Several common types:

• Text/plain (plain text)
• text/html (HTML document)
• Application/xhtml+xml (XHTML documentation)
• Image/jpeg (JPEG image) "PHP: Image/pjpeg"
• Image/gif (GIF image)
• Image/png (PNG image) "PHP: Image/x-png"
• Video/mpeg (MPEG animation)
• Application/pdf (PDF document)
• Application/msword (Microsoft Word file)
• Application/octet-stream (arbitrary binary data)
• Application/x-www-form-urlencoded (Form submitted using the Post method of HTTP)
• Multipart/form-data (IBID., but mainly used when the form submission is accompanied by file upload)

In addition, subtype, which has not yet been accepted as a formal data type, can use an X-starting independent name (for example, Application/x-gzip). The intrinsic name of the vnd-can also be used (example: application/vnd.ms-excel).

Parameter can be used to specify additional information, and in more cases, charset parameters that specify the way text is encoded, such as Text/plain and text/htm. MIME has a default subtype based on type, and when the client cannot determine the subtype of the message, the message is treated as the default subtype. Text default is text/plain,application default is Application/octet-stream and multipart is considered multipart/mixed by default.
