Can anyone suggest or provide a suitable regex. I have tried several variations of

\b\w*\b\s+(\b\w*+\b\s?

but I can’t seem to get an expression which returns the complete expected result set.

$s = "the fox jumped over the rabbit";
$s = split(' ', $s);
$result = array();
foreach ($s as $key => $word)
{
    $r = array();
    for ($i = $key; $i < count($s); $i++)
    {
        $r[] = $s[$i];
        if(count($r) > 1) $result[] = implode(' ', $r);
    }
}
