# Code sample / snippet.
/* In the right circumstances, emailing from a web server is useful.
In the wrong circumstances, it's annoying to the recipient and it
may also be illegal. See module A213 for some further guidance on
this under British (and specifically English) law. If in any
doubt, check with a qualified law firm (which we are NOT) */
$f = "/etc/httpd/logs/access_log";
$boundary = md5(uniqid(time()));
$handle = fopen($f,"r");
$content = chunk_split(base64_encode(fread($handle, filesize($f))));
$head = "MIME-Version: 1.0\r\n".
"Content-type: multipart/mixed; boundary=\"$boundary \"".
"\r\n\r\nThis is a multipart message in MIME format".
$msg = "--$boundary\n".
"Content-type: text/plain; charset=ascii\r\n".
"Content-transfer-encoding: 8 bit\r\n\r\n".
"Access Log file from PHP - sample\r\n".
"Content-type: application/octet-stream; name=access_log\r\n".
uniqid ... provides a unique ID based on the time
md5 ... calculates the md5 hash of a string
base64_encode ... encodes a string to the base 64 standard
chunk_split ... divides a line of text into 76 character
chunks, separating each with a new line sequence
The $boundary variable is set to be a unique 32-character
string which acts as a separator between each of the multiple
parts in the document. Each document part has a header stating
the content type and the encoding method, followed by a body
of data. The boundary is repeated at the very end, with -- on
the end of it to tell the mail reader that it's done.
