explode text but returning each array piece as three words
<p>I'm getting troubles on a simple php function!
What i want to do is:</p>

<pre><code>$text = "this is my data content with many words on it";
</code></pre>

<p>I want to write a function that turns the variable string $text as an array like this:</p>

<pre><code>$array = array("this is my", "data content with", "many words on", "it");
</code></pre>

<p>In other words, each array piece should have 3 words on it!</p>
