PHP Chinese Text data page (Message book page)

MYSQ in the introduction of a lot of pages in the page, and Text data table-style page to introduce a few, here I simply say the page

Mainly introduce the following page thinking
1, the page of the message book
2, the Text forum page

————————————————————————
Page of the message book:
——————————————————————————————
This page in the Text data table is the simplest page to turn, which illustrates

Golbal file
Data.dat---NOTE FILE use
User.dat---Forum File use
Data.dat
_______________________________________________________________________
[1] [postuser] [TITLE] [MEM] [posttime] [IP]
[2] [postuser] [TITLE] [MEM] [posttime] [IP]
[3] [postuser] [TITLE] [MEM] [posttime] [IP]
[4] [postuser] [TITLE] [MEM] [posttime] [IP]
[5] [postuser] [TITLE] [MEM] [posttime] [IP]

Description
Among the [1,2,3,4,5 ...] I added it myself, mainly for the better understanding of everyone.

$fp = file ($file); Read the data into the content

$page = 0; Because it is read from the data text, stored in the array, there is an O subscript

$startnote = $page * $listnumber; Start record location
$endnote = $startnote + $listnumber; End Record Location

"; Here you can directly add the detection of the page here, so that others see is comfortable, but the effect is the same
For example, there may be 20 pages appearing on the next page or

Written in haste, and in the middle there are many because of the use of PHP4.20 so change a bit, such as Php_self has adopted _server["php_self"] and so on
