用PHP生成html分页列表的代码

<?php
$db = mysql_connect("127.0.0.1","root","***") or die("cant't connect host");
$re = mysql_select_db("t",$db)or die ("can't open database");

$sql = "Select * FROM news";
$res = mysql_query($sql);
$row = mysql_num_rows($res);

$pagesize = 2; //分页
行数
if($row<$pagesize) $pages = 1;
if($row%$pagesize){
$pages = intval($row/$pagesize)+1;
}else{
$pages = intval($row/$pagesize);
}

for($i=1;$i<=$pages;$i++){
$page_turn="";
if($i==1){
$indexpath="index.html";
$pageturn.="First | Front";
}else{
$indexpath="index".$i.".html";
$pageturn.="First | <a href='index".($i-1).".html'>Front";
}
if($i==$pages){
$page_turn.=' | Behind | Last';
}else{
$pageturn.=" | <a href='index".($i+1).".html'>Behind | Last";
}
$search = $sql." LIMIT ".($i-1)*$pagesize .", $pagesize";
$result = mysql_query($search);
$rows = mysql_num_rows($result);
$j=1;
$list="";
while($j<=$rows){
$doc = mysql_fetch_array($result);
$id = $doc['0'];
$title = $doc['1'];
$path = $doc['3'];
$list .="".$title."
";
$j+=1;
}
$list.="

".$page_turn;
$fp = fopen("html/list.html","r");
$str = fread($fp,filesize("html/list.html"));
$str = str_replace("{content}",$list,$str);
fclose($fp);

$handle = fopen($path."/".$indexpath,"w");   
fwrite($handle,$str);   
fclose($handle);       

}
copy($path."/index.html",$path."/index_1.html");
?>
