When using the cakephp framework, there is always the cakephp logo in the generated html page (there is a big title CakePHP Rapid Development above, and there is a cakephp icon below). Although it is a cakephp thing, put it in your own project. It always looks unpleasant.
The way to remove it is
to modify cakelibsviewtemplateslayoutsdefault.thtml, which is a general template framework for view files (with header and footer).
In addition:
The extensions of cakephp view files are all thtml. This is the default value. If you want to modify the suffix name, you can also change it.
The modification method is:
find cakelibscontrollercontroller.php and change var $ext='.thtml' to html.
