This is the heredoc syntax

For what - so as not to bother with shielding, hyphenation within the lines and so on. For convenience, in short)

    I will give an example where you can use this function. Well, for example, in PHP code you wrote an if-else condition, like this:

    if(!isset(переменная)) { и сделай что нибудь; } else //и хотим, ну например здесь прикрепить HTML форму,тогда пишем! { print<<<HERE наша форма HERE; }

    Only carefully, this is a capricious function, make sure that after print<<<HERE and HERE; there was not a single space, otherwise the function may not work.

      It is in the version

       print <<< HERE HERE;

      "this feature" does not make sense. To display a large amount of text, simply close the PHP tag and continue to write what should be displayed. It will be more convenient, easier and more understandable.

      Use heredoc only makes sense if a large chunk of text needs to be stored in a variable.
