Problem I'm having is I've inherited a PHP page that contains sections of PHP/Javascript/HTML/CSS all inside of a PHP echo tag.  My PHP and JS skill are rudimentary at best so when it comes to a block of code 40 to 50 lines in length, it becomes daunting to reverse the ' with ".  Each echo block starts with a " and the html inside uses a '.  JS also uses '.

Below is an actual block in more detail with JS in it.  Is it still recommended to switch with " with ' and ' with "?

	  <p>Click on a picture to view that color:</p>";
