Stripping Whitespace PHP

Question

I have a Problem with RegEx and PHP, I have this string:

Panorama - SPIEGEL ONLINE - Nachrichten                                                                                                                                                Schlagzeilen                        Hilfe                        RSS                        Newsletter                        Mobil                        Wetter                        TV-Programm                                                            Dienstag, 26. Februar 2013                                    Panorama                                                                                                                                                                                                                                    NACHRICHTEN                                                                Home                                                                    Politik Deutschland                                                Ausland                                                &nbsp;                                                                                                                                                WirtschaftB

I would like to strip all spaces, which are not needed, so all spaces but one, so that the words are still seperated by one space.
I wrote this regex:

echo trim(preg_replace("/\s+/", " ", $lol));

And I'm very close:

What am I missing? Thank you very much!

Your code is basically right, you just used the wrong kind of quotes. Inside double quotes, you need to escape the backslash, `\\s`. — Barmar, Mar 04 '13 at 23:09

The problem is the  . This is a non-breakable space in your browser. Use this:

$string = "Panorama - SPIEGEL ONLINE - Nachrichten                                                                                                                                                Schlagzeilen                        Hilfe                        RSS                        Newsletter                        Mobil                        Wetter                        TV-Programm                                                            Dienstag, 26.

$string = str_replace("&nbsp;"," ",$string);

echo preg_replace('!\s+!', ' ', $string);
