actually it does... james' solution will work but I forgot to mention a
\s is whitespace, not a space, therefore it will get tabs, newlines, and
spaces. look at http://www.cs.tut.fi/~jkorpela/perl/regexp.html
" \s matches any whitespace character (space, tab, newline)"
therefore my suggestion works:
$t = preg_replace('/\s+/',' ',$text);
its quicker to code, easier to understand, and will run faster because
it doesn't have to match and remember or do alternation...

The example Jack gave you will clear up spaces well, though to get both
newlines and spaces into one:
$input = preg_replace("/([ ]|\n){1,}/", "\\1", $input);
