Send mail with multiple PDF files php - php

Question

I'm trying to send more than one pdf and I didn't found any that works for me.
I tried this How to attach two or multiple files and send mail in PHP
My problem is that only one pdf is attached. Here is my code.
public function sendMultiple($from,$to,$subject,$files){
$eol = PHP_EOL;
$separator = md5(time());
$headers = "From: \"".$from."\" <".$this->replyTo.">\r\n";
$headers .= "MIME-Version: 1.0".$eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol.$eol;
$body = "Content-Transfer-Encoding: 7bit".$eol;
$body .= "This is a MIME encoded message.".$eol;
$body .= "--".$separator.$eol;
$body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
$body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$body .= $this->getMessage().$eol;
foreach ($files as $file ) {
$body .= "--" . $separator . $eol;
$body .= "Content-Type: application/octet-stream; name=\"" . $file['name'] . "\"" . $eol;
$body .= "Content-Transfer-Encoding: base64" . $eol;
$body .= "Content-Disposition: attachment" . $eol . $eol;
$body .= $file['file'] . $eol;
$body .= "--" . $separator . "--";
}
$mail = mail($to,$subject,$body,$headers);
if($mail){
return true;
}
return null;
}
//$files is an array of this
$file1 = array("name"=>"name".$name1.".pdf","file"=>chunk_split(base64_encode($pdf)));
$file2 = array("name"=>"name".$name2.".pdf","file"=>chunk_split(base64_encode($pdf2)));
array_push($files, $file1);
array_push($files, $file2);

I solved the problem, here is the code:
public function sendMultiple($from,$to,$subject,$files){
$eol = PHP_EOL;
$separator = md5(time());
$headers = "From: \"".$from."\" <".$this->replyTo.">\r\n";
$headers .= "MIME-Version: 1.0".$eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol.$eol;
$body = "Content-Transfer-Encoding: 7bit".$eol;
$body .= "This is a MIME encoded message.".$eol;
$body .= "--".$separator.$eol;
$body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
$body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$body .= $this->getMessage().$eol;
foreach ($files as $file ) {
$body .= "--" . $separator . $eol;
$body .= "Content-Type: application/octet-stream; name=\"" . $file['name'] . "\"" . $eol;
$body .= "Content-Transfer-Encoding: base64" . $eol;
$body .= "Content-Disposition: attachment" . $eol . $eol;
$body .= $file['file'] . $eol;
//This line is not needed, solved the issue
//$body .= "--" . $separator . "--";
}
$mail = mail($to,$subject,$body,$headers);
if($mail){
return true;
}
return null;
}
//$files is an array of this
$file1 = array("name"=>"name".$name1.".pdf","file"=>chunk_split(base64_encode($pdf)));
$file2 = array("name"=>"name".$name2.".pdf","file"=>chunk_split(base64_encode($pdf2)));
array_push($files, $file1);
array_push($files, $file2);
