It can be said to be a non-technical method:
Copy and rename Page.class.php, such as nPage.class.php.
And in nPage.calss.php Lieutenant General
$this->varPage=C('VAR_PAGE')?C('VAR_PAGE'):'p'
is changed to
$this->varPage=C('VAR_PAGE')?C('VAR_PAGE'):'np'
Of course, remember to change the class name to nPage.class.php, and then just add it in php If you directly reference this class paging, it will not conflict with the original...
