A simple template engine class, which is not perfect for research purposes only. I hope some friends can join in the study.
This is the first post code here. this code is mainly used for PHP template engine technology research. Currently, only the compiled version is available. I hope you will provide more comments and optimization skills.
It consists of three files. I don't know how to copy them as files. sorry!
Index. php is a configuration file. you can see it.
Index.html examples
Templates. class. php base class
A well-developed version with a cache will be released later, but I hope it will not be written to the cache. some friends or experts may advise that this template engine only needs to process compilation and cache, and other considerations will not be considered for the time being, of course, the regular expression replacement mode also requires f, w, and so on...
I hope a friend can study me. Q: 76376931

The Copy_3_of_Templates.class.php file has been added to the cache mode. if you refresh the page again, the cache will not be generated. if you do not want to cache some pages in the project, you will use this class to add them gradually. I hope you can communicate with me!

  1. Header ('content-Type: text/html; charset = utf-8 ');
  2. Define ('root _ host', dirname (_ FILE __));
  3. Define ('HTML _ dir', ROOT_HOST. '/moban /');
  4. Define ('compiled _ dir', ROOT_HOST. '/data/COMPILED /');
  5. Define ('cache _ dir', ROOT_HOST. '/data/CACHE /');
  6. // Whether to enable the buffer
  7. Define ('New _ cache', false );
  8. // Determine whether the buffer zone is enabled
  9. NEW_CACHE? Ob_start (): null;
  10. // Introduce the template class
  11. Require ROOT_HOST. '/lib/Templates. class. php ';
  13. $ _ Moban = new Templates ();
  15. $ Array = array (a => 'Hi! ', B =>' I am not very good, but I miss you very much ', c =>' You are all at home, why do you still miss me? ');
  16. $ Xcvu = 'Hello, this is an xcvu ';
  17. $ Zmq = "hi ";
  18. $ Title = "this is a template engine custom method! ";
  19. $ Ling = "because a" function "???????????????? ";
  21. $ _ Moban-> assign ('ling', $ ling );
  22. $ _ Moban-> assign ('title', $ title );
  23. $ _ Moban-> assign ('zrabbit', $ zmq );
  24. $ _ Moban-> assign ('xcvu', $ xcvu );
  25. $ _ Moban-> assign ('ABC', 5> 4 );
  26. $ _ Moban-> assign ('array', $ array );
  27. $ _ Moban-> display('index.html ');
