Using Pear Mail to mail with attachment - php

Question

I have a script I run to send emails with attachments.
On my old server it worked perfectly, But since moving a few days back. The script no longer works. As soon as it is supposed to send a mail, it bombs out.
I did find this error in the error log file,How can I locate the problem?
[08-Jul-2015 12:39:17 UTC] PHP Fatal error: Call to undefined function mime_content_type() in /home/username/public_html/editor/cronjob.php on line 79
My code more or less looks like the below:
function sendmailwithattachment($from,$to,$subject,$body,$host,$username,$password,$body_id,$port) {
$query = "SELECT * FROM `email_attachments` where `email_id`='$body_id';";
if($result = mysqli_query($this->link, $query)){
if($result->num_rows!=0){
$headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject);
$crlf = "\n";
$mime = new Mail_mime($crlf);
$mime->setHTMLBody($body);
while ($row = mysqli_fetch_array($result,1)) {
$attachment=$row['attachment'];
$mime->addAttachment($attachment, mime_content_type($attachment));
}
$body = $mime->get();
$headers = $mime->headers($headers);
} else {
$headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject,'Content-type' => 'text/html;charset=iso-8859-1');
$body = $body;
}
}
$smtp = Mail::factory('smtp',
array ('host' => $host,
'port' => $port,
'auth' => true,
'username' => $username,
'password' => $password));
$mail=$smtp->send($to, $headers, $body);
if (PEAR::isError($mail)) {
echo "<p>Message not sent:".$mail->getMessage()."</p>";
return $mail->getMessage();
} else {
//echo "<p>Message successfully sent!</p>";
return 'sent';
}
}

It looks like mime_content_type() is deprecated anyway, try replacing it with Fileinfo functions as they mention in the docs. It might solve your problem in the process (though hard to say, because we don't know what your code looks like).
