title: Does someone have a PHP function to properly capitalize people names?
body: <p>I'm looking for a function to properly capitalize names like McDonald, FitzGerald, MacArthur, O'Lunney's, Theo de Raadt, etc.</p>
  
  <p>Does anyone know of one that works resonably well? I'm guessing any function is not going to support every possibility.</p>
  
  <p>Of course ucwords alone doesn't work for this because it just capitalize the first letter of every word.</p>
  
  <p><strong>Edit:</strong> I know there are going to be problems and all the possibility are not going to be supported. But the issue right now is I have a database of around 50 000 names that are mostly entered in all caps and it would be a pain in the ass to have to edit each one without causing spelling errors. Having a script that causes a problem with 20% would be a whole lot faster and result in a lot fewer errors.</p>
