title: phpStorm showing php syntax in just some .ctp files
body: <p>I am using phpStorm a while, and now I am experiencing something that doesn't make sense.
  I always used .ctp files as HTML and php syntax. And it work pretty fine.</p>
  
  <p>But now, I've declared a function as "<em>between</em>", and phpStorm cannot help with any syntax in the between.ctp file.</p>
  
  <p>I mean, if I rename the file to something like "_<em>between</em>", it works, and any other name the syntax works. Just this name doesn't, I do not have any idea of why.</p>
  
  <p>Ok, probably a bug.
  But I need to figure it out why, and resolve it. I need this function name to be "<em>between</em>"</p>
  
  <p>Thanks in advance.</p>
