<?php
/*
this class encapsulates the PHP mail() function.
implements CC, Bcc, Priority headers
@version 1.3
- added ReplyTo( $address ) method
- added Receipt() method - to add a mail receipt
- added optionnal charset parameter to Body() method. this should fix charset problem on some mail clients
@example
$m= new Mail; // create the mail
$m->From( "leo@isp.com" );
$m->To( "destination@somewhere.fr" );
$m->Subject( "the subject of the mail" );
$message= "Hello world!\nthis is a test of the Mail class\nplease ignore\nThanks.";
$m->Body( $message); // set the body
$m->Cc( "someone@somewhere.fr");
$m->Bcc( "someoneelse@somewhere.fr");
$m->Priority(4) ; // set the priority to Low
$m->Attach( "/home/leo/toto.gif", "image/gif" ) ; // attach a file of type image/gif
//alternatively u can get the attachment uploaded from a form
//and retreive the filename and filetype and pass it to attach methos
$m->Send(); // send the mail
echo "the mail below has been sent:<br><pre>", $m->Get(), "</pre>";
