$str = preg_replace('/\s+/', ' ', $str);

You don't need both space characters, as the + symbol matches one or
more, which is just what you want.

Be careful about the word "spaces" do you mean exactly " "; or white spaces
defined by "\s", which include spaces, tabs CRLFs.

If you want specifically spaces and not all white spaces, then use "\x20"

reg_replace("%\x20+%", " ", $str);//note the space between the quotes in the
replace.

If our string has CRLFs [i.e., newlines] then they will all will be reduced to
one. e.g., " \n\n\n" will end up as " \n" if you use \s.

Also take into account the pattern modifier "m" (PCRE_MULTILINE). It may apply
in your case.
