Porcjowanie wynikow Opcje

[stal-sw]

Jak zauwazylem bardzo wiele osob ma problemy z porcjowaniem wynikow z bazy danych (ja tez z tym mialem problem).
Ale po dlugich poszukiwaniach znalazlem bardzo ciekawa klase do porcjowania (na http://www.phpclasses.org/)
Sklada sie ona z 2 plikow:
page.inc.php (tego pliku nie trzeba nic modyfikowac)
example.php (ten plik wyswietla rezultaty z bazy i je porcjuje)

Mysle ze kazdy majac te pliki poradzi sobie z porcjowaniem wynikow !

page.inc.php

* Useage:

* $p->file="ttt.php"; // Set used the class name,default to the PHP_SELF
* $p->pvar="pagecount"; // Set the page parameter,default to "p"
* $p->setvar(array("a" => '1', "b" => '2')); // Set the parameter u wanta pass, Note:used it above the $p->set
* $p->set(20,2000,1); // Set the object parameter,total 3,1st is the pagesize,2nd is the total record count,3rd is the currerent page count,default is will auto read the GET variable
* $p->output(0); // Output,the parameter is true will return a string
* echo $p->limit(0); // Out put the limit.eg. "SELECT * FROM TABLE LIMIT {$p->limit()}"; set it true,will return a array
