This regular expression matches either "the quick" or "brown fox".
However, as the regex is not anchored, it also matches "the brown fox",
for instance.

You can use non-capturing subexpressions[1] to group arbitrarily, e.g.

  preg_match('/^the (?:quick/brown) fox$/', $s, $m)

matches either "the quick fox" or "the brown fox".

Well, just try the following:

  preg_match_all("/^\s+(?:(the) (quick)|brown (fox))\s+$/", $s, $m)

Set $s = ' the quick ' and ' brown fox ', respectively, and then inspect
$m.  In the first case, $m[3] is empty, in the second case $m[1] and
$m[2] are empty, so you can distinguish between both cases by checking
these conditions.

Using named subpatterns might simplify the logic.
