* Page ([total number of records = 1], [page size = 20], [current page = 1], [display page size = 6], [paging parameter = 'page'], [paging link = current page], [static = false])
* Dynamic:
* Simple usage:
* $ Page = new page (50 );
* $ Page-> setpager ('zjj ','

Total {recordcount} items on the {pageindex} page/total {pagecount} page: {first} {prev} {list} {next} {last} to the {jump} page

', Array ("listlong" => "6", "first" => "homepage", "last" => "last page ", "prev" => "previous page", "next" => "next page", "list" => "page *", "jump" => "select "));
* Echo $ page-> getpager ('zjj ');
* Full parameter usage:
* $ Page = new page (50, 20, 'page', 'prrr. php', false );
* $ Page-> setpager ('zjj ','

Total {recordcount} items on the {pageindex} page/total {pagecount} page: {first} {prev} {list} {next} {last} to the {jump} page

', Array ("listlong" => "6", "first" => "homepage", "last" => "last page ", "prev" => "previous page", "next" => "next page", "list" => "page *", "jump" => "select "));
* Echo $ page-> getpager ('zjj ');
* Static:
* $ Page = new page(50,20,1,6, 'page', 'prrr?page=.html ', true );
* $ Page-> setpager ('zjj ','

Total {recordcount} items on the {pageindex} page/total {pagecount} page: {first} {prev} {list} {next} {last} to the {jump} page
