以下に段落がありますが、そこから欲しいのは、ピリオドの終わりごとの最初の単語です。

$paragraph="Microsoft is writing down $6.2 billion of the goodwill within its OSD. It's worth noting that at the time of the acquisition, the company recorded $5.3 billion of goodwill assigned to the OSD, bringing its total carrying balance up to $5.9 billion in September of that year. The goodwill in the OSD had climbed up to $6.4 billion by March of this year, so this accounting charge is wiping out the vast majority of that figure.";

たとえば、私はこれを行うことができます。

$sentences=explode('.',$paragraph);
print_r( $sentences);

そしてそれは印刷します
