mail with attachment not being sent (wierd case)? - php

Question

This code to send an html file as an attachment is working properly. However in the next code snippet,when I cahnge the attachment to an image it is not being sent.Why is it so?I don't want to use phpmailer or swift mail!
<?php
$file_path = "file.html"; // server path where file is placed
$file_path_type = "text/html"; // File Type
$file_path_name = "newfilename.html"; // this file name will be used at reciever end
$from = "xyz#gmail.com"; // E-mail address of sender
$to = "abc#gmail.com"; // E-mail address of reciever
$subject = "Please check the Attachment."; // Subject of email
$message = "This is the message body.<br><br>Thank You!<br><a href='http://7tech.co.in'>7tech.co.in Team</a>";
$headers = "From: ".$from;
$file = fopen($file_path,'rb');
$data = fread($file,filesize($file_path));
fclose($file);
$rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message .= "\n\n";
$data = chunk_split(base64_encode($data));
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$file_path_type};\n" .
" name=\"{$file_path_name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$file_path_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";
if(#mail($to, $subject, $message, $headers)) {
echo "File send!";
} else {
echo 'Failed';
}
?>
Now when I change the attached file to an image i.e. screenshot.png it fails to send the message.
<?php
$file_path = "screenshot.png"; // server path where file is placed
$file_path_type = "image/png"; // File Type
$file_path_name = "screenshot.png"; // this file name will be used at reciever end
$from = "xyz#gmail.com"; // E-mail address of sender
$to = "abc#gmail.com"; // E-mail address of reciever
$subject = "Please check the Attachment."; // Subject of email
$message = "This is the message body.<br><br>Thank You!<br><a href='http://7tech.co.in'>7tech.co.in Team</a>";
$headers = "From: ".$from;
$file = fopen($file_path,'rb');
$data = fread($file,filesize($file_path));
fclose($file);
$rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message .= "\n\n";
$data = chunk_split(base64_encode($data));
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$file_path_type};\n" .
" name=\"{$file_path_name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$file_path_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";
if(#mail($to, $subject, $message, $headers)) {
echo "File send!";
} else {
echo 'Failed';
}
?>
Can you guys point out the error.I've tried to cahnge content type too at 1-2 places but it wasn't working.Am I missing anything?

Use
file_get_contents('http://www.example.com/');
Instead of
$file = fopen($file_path,'rb');
$data = fread($file,filesize($file_path));
fclose($file);
and try with this code..
$random_hash = md5(time());
$headers .= "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\"";
$headers .= "\r\nMIME-Version 1.0";
$attachment = chunk_split(base64_encode(file_get_contents($filename)));
$message =
"--PHP-alt-$random_hash
Content-Type: text/plain

--PHP-alt-$random_hash

Content-Disposition: attachment
$attachment

#mail($to, $subject, $message, $headers);
