$file = "data.dat"; "data file
if(file_exits($file)){ 🎜> fclose($fp);
unset($fp);
}
$listnumber = 20; //Number of items displayed per page
$fp = file ($file); // Read data into the content
$number ){
print "No records yet, please leave a message";
/*+-------------------------------- ---+
|Print the FORM form here or connect to the form |
| URL, |

+------------------- -------------+*/
}else{
if(empty($_POST["page"])){ //This paragraph IF...ELSE.. .It was written to be compatible with the default settings of php4.20 and prevent invalid global variables.
🎜> }else{
$page = $_POST["page"]
}

if($page<0 || $page>pagenumber){ //Error detection processing, when the page parameter jumps out of the total page or is less than the home page (0), it will return to the first page
$page=0;
}

$startnote = $page*$listnumber; //Start recording position
$endnote =$startnote+$listnumber; //End recording position

//for($int_a=$startnote;$int_a<$endnote;$int_a++){ //The sorting display is similar to ASC mode

pirnt "

"

for($ int_a=$endnote;$int_a>=$startnote;$int_a--){ //Sorting is similar to DESC mode
To obtain the detailed data of each record, I used a TAB key to separate it
print "

User: $info[1] Title $info[2] Speech content: $info[3 ] Release time: $info[4] IP: $info[5]";
}

$prevpage = $page-1; //Number of PAGEs on the previous page
$nextpage = $page+1; >Homepage
Previous page
Next page
Last page< /a>
< There may be 20 pages appearing. Next page or
}
?>
---====EOF====---

Written in a hurry, and there are a lot of mistakes in the middle because of the consideration of using PHP4.20 So I changed it a bit, for example, PHP_SELF has adopted _SERVER["PHP_SELF"], etc.
