Skip certain sentence in parsing text
<p>I wanna parse text. There's a strange sentence like <code>B R I E F I N G S I N B I O I N F O R M A T I C S</code> I wanna skip theat sentence. here's the code</p>

<pre><code>&lt;?php
$text = 'B R I E F I N G S I N B I O I N F O R M A T I C S. Because many biomedical entities have multiple names and abbreviations, it would be advantageous to have an automated means to collect these synonyms and abbreviations to aid users doing literature searches.';

$reg = '/(?&lt;=[.!?]|[.!?][\'"])\s+/';
foreach(preg_split($reg, $text, -1, PREG_SPLIT_NO_EMPTY) as $sentence){
    foreach(preg_split('/\s+/', $sentence) as $words){
       if (count(strlen($words)&gt;1)){
        //I don't know what to do
    }
    }
}
?&gt;
</code></pre>

<p>But, it still wrong, how to recognize pattern sentence like <code>B R I E F I N G S I N B I O I N F O R M A T I C S</code> ? thank you</p>
