title: Find whole word with strpos()
body: <p>Hello people :)
  I'm trying to use strpos() to find whole words in a sentence. But at the moment, it also find the word if it just are a part of another word. For example:</p>
  
  <pre><code>$mystring = "It's a beautiful morning today!";
  $findme   = "a";
  
  $pos = strpos($mystring, $findme);
  </code></pre>
  
  <p>In this example it would find "a" in the word "a" (as it should do), but also in "beautiful" because there is an a in it.</p>
  
  <p>How can i find only whole words and not if it is a part of other words?</p>
