Sending Mails with Attachment in PHP

Here is the code for sending for mails with Attachments in PHP.

$email_from = "Anil Kumar"; // Who the email is from
$email_subject = "Email with Attachment"; // The Subject of the email
$email_message = "Is the File Attached."; // Message that the email has in it

$email_to = "anilbuddha@gmail.com"; // Who the email is too

$headers = "From: ".$email_from;


$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";

$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_message . "\n\n";

/********************************************** First File ********************************************/


$fileatt = "../reports/users.pdf"; // Path to the file
$fileatt_type = "application/pdf"; // File Type
$fileatt_name = "users"; // Filename that will be used for the file as the attachment

$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);


$data = chunk_split(base64_encode($data));

$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}\n";
unset($data);
unset($file);
unset($fileatt);
unset($fileatt_type);
unset($fileatt_name);
$ok = mail($email_to, $email_subject, $email_message, $headers);

if($ok) {
echo "Email With Attachment has been Sent Successfully";
} else {
echo "Sending Email with Attachment has Failed. Please check the Code Added";
