1. On Unix platformIU - installed and configured sendmail. If the path
   not in the environment, then you need to specify php.ini sendmail_path = / path / to / sendmail
   -t-i in the section [mail function].
   
2. On the Windows platform - have a SMTP server. Its parameters must be specified in
   php.ini section [mail function]:
   
   SMTP = 192.168.1.1
   
   sendmail_from = admin@example.com
   

<font color="#0000CC"> mail </ font> <font color="#006600"> (</ font> <font color = "# CC0000 "> whom </ font>, <font color="#CC0000"> Theme </ font>, <font color="#CC0000"> body </ font>, [<font color="#CC0000"> additional
headers </ font>, [<font color="#CC0000"> parameters </ font>]] <font color = "# 006600 ">)</ font>

1. To (copy and Bcc specified additional headers):
   
   
   
   • nobody@example.com
     
   • John Smith<nobody@example.com>
     
   • nobody@example.com, pupkin@example.com
     
   • John Smith <nobody@example.com>, Ivan Pupkin <pupkin@example.com>
     
   • Theme - a text without newline characters
     
   • The body - any text, including HTML or MIME
     
   • Headers - here you can use these headers: From: Cc: Bcc: MIME-Version:
     Content-type: Reply-To: X-Mailer: X-Priority: Date: Content-Transfer-Encoding:
     
     
     
     • From - From: "pupkin@example.com" or "Ivan Pupkin <pupkin@example.com>"
       
     • Cc - Cc: as well as "who"
       
     • Bcc - Bcc: as well as "Who" works only on
       Unix
       Reply-To - if you need to substitute the recipient's response, other than the sender
       
     • X-Priority - the importance of the message (default 3)
       
     
     

     Titles are separated by <font color="#0000CC"> \ r \ n </ font> (on Unix, you can
     only the <font color = & quot; # 0000CC "> \ n </ font>)

     
     

If a letter is sent in HTML format, you must set the following
2 lines in the headlines: <br>
<blockquote> MIME-Version: 1.0 \ r \ n; <br>
Content-Type: text / html; charset = & quot; windows-1251 "</ blockquote>

I want to send a letter to attachmentom (s) (such as HTML with images)

MIME-Version: 1.0 \ r \ n <br>
Content-Type: multipart / mixed; boundary = "$ delimiter" Where $ delimiter - any line, can be random. multipart / mixed, you can replace
for multipart / alternative.

$ delimiter ="----=_ Razdelitel_Blokov_ =----"

And in the body of the message to divide the different types of data boundary ($ delimiter) and indicate their Content-Type:

<? php
$ body = "This is a multi-part message in MIME format."; <br>
$ body .= "\ r \ n \ r \ n". $ delimiter; <br>
$ body .= "Content-Type: text / plain; charset = \" windows-1251 \ "\ r \ n \ r \ n"; <br>
$ body .= "Content-Transfer-Encoding: quoted-printable "; <br>
$ body .= "Hello, Ivan! I send you as promised to the picture and summary"; <br>
$ body .= "\ r \ n \ r \ n". $ delimiter; <br>
$ body .= "Content-Type: image / jpeg; name = \" meeting.jpg \ ""; <br>
$ body .= &quot; Content-Transfer-Encoding: base64 "; <br>
$ body .= "Content-Disposition: attachment; filename = \" meeting.jpg \ "\ r \ n \ r \ n"; <br>
$ body .= base64_encode ($ file1); <br>
$ body .= "\ r \ n \ r \ n". $ delimiter; <br>
$ body .= "Content-Type:application / msword; name = \ "referat.doc \" ";
<br>
$ body .= "Content-Transfer-Encoding: base64"; <br>
$ body .= "Content-Disposition: attachment; filename = \" referat.doc \ "\ r \ n \ r \ n"; <br>
$ body .= base64_encode ($ file2); <br> <br /> $ body .= "\ r \ n \ r \ n". $ delimiter;
