สอบถามเรื่องการส่ง E-mail แบบมีการแนบไฟล์หน่อยครับ

header('Content-Type: text/html; charset=UTF-8');
	$mail_send=$_POST["to_sender"];
	$from_sender=$_POST["from_sender"];
	$subject_sender=iconv("UTF-8","windows-874",$_POST["subject_sender"]);
	$message_sender=iconv("UTF-8","windows-874",$_POST["message_sender"]);
	
	$strTo =$mail_send."@ctu.ac.th";
	$strSubject = $subject_sender;
	$strHeader = "From: ".$from_sender;
	$strMessage = $message_sender;
	
	// Attachment
	if($_FILES["fileAttach"]["name"] != ""){
		$strFilesName = $_FILES["fileAttach"]["name"];
		$strContent = chunk_split(base64_encode(file_get_contents($_FILES["fileAttach"]["tmp_name"]))); 
		$strHeader .= "\n";
		$strHeader .= "Content-Type: application/octet-stream; name=\"".$strFilesName."\"\n"; 
		$strHeader .= "Content-Transfer-Encoding: base64\n";
		$strHeader .= "Content-Disposition: attachment; filename=\"".$strFilesName."\"\n\n";
		$strHeader .= $strContent."\n\n";
	}
	
	$flgSend = @mail($strTo,$strSubject,$strMessage,$strHeader);  // @ = No Show Error //
	if($flgSend){
			echo 1;	
		}else{
			echo 0;
		}
