  short_open_tag
  

  Is the property you seek.

  Syom : @Bisko Thanks man;) it can be `On` or `Off` ?

  bisko : Sure, It must be ON to allow

  Syom : ie. it doesn't work in versions >= 5.3.0 ???

  Richard Knop : No it doesn't work for version >= 5.3.0.

• It is:

  short_open_tag

  Make sure to read:

  • PHP Short Open Tag: Convenient Shortcut or Short Changing Security?

• It's already been said how to do it, but I'm just saying that it might not be such a great idea. Almost anyone you ask will tell you not to use short tags. Unless you have a specific reason to use short tags, you should just type <?php. It's only 3 more characters.
