I am just in the process of transferring a website, but on the new server I am getting garbage text at the top of the page. See http://46.32.231.136/~marblele/

The software used on this website is http://www.open-realty.org

Any idea why the garbage text is there and how to get rid of it?

Looks like Unicode characters in one of your pages.

Check you top level pages i.e. open them and have a look, (and make sure they are encoded as UTF-8 without BOM as this will make sure any Unicode will show up incase they are 'hidden')

Looks like invalid Unicode characters!

This will give you a little more guidance about character-encoding issues.

The fact that the pattern of junk is repeated four times might be an important clue.  How many include() steps are done before the browser output is started?  If it's four, you may find that all of your sub-scripts are spitting out a bit of junk.

Thanks for the advice all. I have narrowed the issue down to the code below...

error_reporting(E_ALL& ~E_NOTICE);
global $lang;
$lang = array();
if ($handle = opendir(dirname(__FILE__).'/versions')) {
	while (false !== ($file = readdir($handle))) {
		if ($file != "." && $file != ".." && $file != "CVS" && $file != ".svn") {
			if (!is_dir(dirname(__FILE__).'/versions/' . $file)) {
				include(dirname(__FILE__).'/versions/' . $file);
				}
			}
		}
	closedir($handle);
	}
if ($handle = opendir(dirname(__FILE__).'/custom')) {
	while (false !== ($file = readdir($handle))) {
		if ($file != "." && $file != ".." && $file != "CVS" && $file != ".svn") {
			if (!is_dir(dirname(__FILE__).'/custom/' . $file)) {
				include(dirname(__FILE__).'/custom/' . $file);
				}
			}
		}
	closedir($handle);
	}

Open in new window


Any idea what is wrong with the above?

There might be nothing wrong with the above.  All it does is include() some files.  You might want to look into those /versions/ and /custom/ directories.  Open each of the files in those directories with a text editor (not Notepad) and save them in UTF-8 without Byte Order Marks.  I am not sure this will fix it, but there is a chance it might.  

Another thing to look for would be garbage in the files themselves.

You might also want to rethink this:
error_reporting(E_ALL& ~E_NOTICE);

What that line of code means to you is that if you make a typographical error somewhere in that script or in any other script included after that script, PHP will not tell you about it.  Instead PHP will silently ignore reliance on undefined variables.  This is AntiPractice #4 -- it can make debugging very, very difficult.

You might also want to ask yourself what purpose the $lang variable plays.  It appears to be injected into the symbol table, and made global (why?) but not used in the script.
