Removing white space in the middle of a string

[Doc Thirst]

Hey, I found this snippet on in the manual. Could someone please explain how it works (specifically the ' +')

$string = ereg_replace (' +', ' ', $string);

Thanks!

[Doc Thirst]

I get it now:

'_+' = one or more
'__+' = two or more
'___+' = three or more

and so on.

Tip
preg_replace(), which uses a Perl-compatible regular expression syntax, is often a faster alternative to ereg_replace().

If you haven't yet learned about regular expressions, I'd recommend you learn about Perl-compatible ones. Here's a good tutorial on them: http://tote-taste.de/X-Project/regex/index.php
Good luck
