search query parsing - regexp help

[Anon]

I'm trying to create a google-like query parser.

I want:

$string = 'foo bar "you betcha"';
$word = split('<<some regexp>>', $string);
while (list($index, $s) = each($word)){
echo "$index =&gt; $s<br>";
}

to print the following:

0 => foo
1 => bar
2 => you betcha

but I can't seem to figure out the right regular expression. I tried this one, but it didn't work at all (it just returned the entire string unaltered):

(^[ ].[ ]$)|(^["].["]$)

What am I doing wrong?

Thanks!!!
