Removing excess spaces?

[zeroblitzt]

Hey all, i'm a total regex beginner (never used it), but someone recommended that I use it. What I need to do with it is remove excess spaces from a string (for my message boards).

So if I were to have, say:
[pre]Hello    Everyone[/pre]

it would shorten it down to
[pre]Hello Everyone[/pre]

I'm not sure how to go about doing it though. Any tips?

[xec]

its very easy ,

(\040)+  -- this is the meta character represent space.. and + sign represent if you want to remove multiple spaces. ;)

You can use this little preg_replace:
[code=php]<?php
$string = trim (preg_replace ('`[\s]+`', ' ', $string));
?>[/code]

Hope it helps ;)
