Languages :: PHP :: Creating multipart emails with PHP

Quality : Excellent
Ok I know I'm reinventing the wheel but I'm trying to create a webmail application using PHP. I want it to be able to create emails with attachments, so far I have managed to create the email, use the multipart boundry stuff to create a mail that my email client (outlook;opera etc) recognises as an attachment and send it, so far so good. The problem comes when I try to attach binary files such as jpeg's, I am using this function:
function encodedata(){
$rawfilepointer=fopen($this->filename,'r');
//or die("Failed opening file");
if($rawfilepointer==0){

$this->errstr="Failed opening file";

return 0;

}

$rawfile=fread($rawfilepointer,filesize($this->filename));

fclose($rawfilepointer);

return chunk_split(base64_encode($rawfile));

}

to base64 encode the data but something isnt working. The email looks like it has an attachment but the client is failing to decode it properly.
Any clues on this issue recieved gratefully.

Thanks
Mal

no problem

see this as a basis :

this is for one attachment, but you will easily understand that looping on AddAttachment($filepathes) will do the trick.

Apologies for the lack of feedback, the functions do work perfectly well but I was trying to find out why my versions of the same were not working correctly. Since your code is commented in french, not my first language I didnt find your code to be particually helpful for debuging however I am grateful for your answer.
