Calling AddAttachment in PHPMailer does not send mail - php

Question

I am implementing mail utility in my PHP web application. It works fine for simple email. But if try to attach any file, send function of PHPMailer is not called i.e. mail is not sent and it is not showing any error also. Below is my sample code:
HTML Form
<form action="Email.php" enctype="multipart/form-data" method="POST">
<input type="text" name = "to" id="to">
<br>
<input type="file" name="file" id="file">
<br>
<input type="text" name="subject" id="subject" size="155"><br>
<textarea rows="10" cols="50" name="msg" id="msg">
</textarea>
<br>
<input type="submit" value="Send Mail">
</form>
PHP Code
include 'library.php';
include "class.phpmailer.php";
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 1;
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;
$mail->Username = USERNAME;
$mail->Password = USERPASS;
$mail->SetFrom(USERNAME);
$mail->Subject =$_POST['subject'];
$mail->MsgHTML($_POST['msg']);
$mail->IsHTML(true);
$mail->AddAddress($_POST['to']);
if (!empty($_FILES['file']['tmp_name']))
{
move_uploaded_file($_FILES["file"]["tmp_name"],"Upload/" . $_FILES["file"]["name"]);
if(!$mail->AddAttachment("Upload/" . $_FILES['file']['name']))
{
echo "Error in attachments";
}
else
{
echo "File Attached";
}
}
$result = $mail->Send();
echo $result;
if(!$result) {
echo 'Error sending email' . $mail->ErrorInfo;
}
else{
echo "Email Sent";
}
Output of this code is following:
File Attached
After this no message is displayed and also mail is not sent from the id provided. But if I don't add any attachments it will work fine.

I have resolved this problem. Solution is I was trying to add file with 350KB which was taking more time and was throwing error of exceeded 30 sec. I just increased my time limit and problem is solved. Thank you all for helping.
