title: Check a string for alphabetically ordered characters
body: <p>This seems so obvious , but I cannot find a way to do this.<br>
  I think there even is a regular PHP function to do this, but even that one stays well hidden after 1,5 hours of intensive Google searches.<br><br></p>
  <h1>What I want</h1>
  <ul>
  <li>A function that takes a string as input.<br></li>
  <li>Checks that string for the number of times it has alphabetical orderded sequences of more than 3 characters: <br></li>
  <li>returns true if a sequence of more than 3 has been found.<br><br></li>
  </ul>
  <h1>Example</h1>
  <p><b>&quot;youlookgreatbcdetoday&quot;</b> =&gt;  has &quot;bcde&quot; in it ... so has to return true<br>
  <b>&quot;youlookgreatklmtoday&quot;</b>  =&gt;  only has &quot;klm&quot; in it ... so that has to return false<br>
  <b>&quot;youlookgreattoday&quot;</b>     =&gt;  has no alphabetically ordered sequences in it, so returns false<br></p>
  <br>
  <h1>Possible usecase</h1>
  <ul>
  <li>password strength checker</li>
  <li>wordgame</li>
  <li>...</li>
  </ul>
  <p><i><b>disclaimer:</b> I wish I already had some code to show you, but I literally have nothing yet.<br>Only thing I could come up with was to split the string up in an array and do some magic on the array ... but even then I got stuck.</i><br></p>
  <p>Hope one of you will save me :)</p>
