1) heredoc is great for not caring about escaping ' or ". Whether or
not you like the syntax it's not hard to use in any way.
2) stay away from eval. Just don't use it unless you have no other choice
3) the include+output buffering solution is much better. Another
option would be to use markers in your templates and then just replace
them with content. Whether or not that would suit you depends on what
kinds of templates you're making and for what purpose
