Extra \r\n using include() on wamp

I imagine there is something inside that file that is outputting the carriage return and new line characters. Can we see what's in there?

note:though it is not required, it is always good practice to write constants in upper case, makes them easy to identify.

Thanks. Code looks like this. The extra CRLF after the closing <?php> code... <?> is the source of the problem.
I wonder why this is only a problem in WAMP but not on Linux. Further, I would think there would need to be explicit echo calls to output to responsetext, rather than just random \r\n at the end of the included files.

Code:

              url = $thisurl + '/checkfield.php?type='+type+'&name=' + field.value;
              checkitxmlhttp = new myXMLHttpRequest ();
              checkitxmlhttp.open ("GET", url, true);
              checkitxmlhttp.onreadystatechange = function () {
                      if (checkitxmlhttp.readyState == 4) {
                      responsestring = checkitxmlhttp.responseText;

Code:

       
      //checkfield.php -------------------------------------
      include_once('Smarty.class.php');
      $main_smarty = new Smarty;
      echo "1";
      include('config.php');
      echo "2";
      include(mnminclude.'html1.php');
      echo "3";

//output --------------------------------------------
"1\r\n\r\n2\r\n 3"

It could be anything from the way the operating-systems handles files to the way your PHP editor saves files. (Some of them trim trailing white-spaces, some don't).

It's best just to make sure there is no room for misinterpretati on by not leaving white-spaces where they shouldn't be.

Anything outside <?php ?> tags is usually considered HTML by Apache and added to the output accordingly.
Consider this:
[code=php]
<html>
<head><title>Te st</tile></head>
<body>
<table>
<?php
for($i = 0; $i < 5; ++$i) {
echo "<tr>";
for($j = 0; $j < 5; ++$j) {
echo "<td>", pow($j, $i), "</td>";
}
echo "</tr>";
}
?>
</table>
</body>
</html>[/code]
If nothing unless the echo statements made it to the output, this type of syntax could not be used.

And keep in mind that a HTML infused PHP code like that is often included. In fact, I'm pretty sure the Smarty template engine does a lot of that.

Well, the issue is say I have some code that expects well formatted XML. And then I add a module which has extra \r\n in the php file. Now those \r\n makes the XML un-parse-able. It's possible to catch this, but not a pretty solution, especially if you don't have control over 3rd party modules.

I have searched around, I am surprised that I haven't found other people with this issue.
