<?php  
if($_POST[button]){  

$sql="select * from doorsjk_about where id<12";  
$rs=$db->query($sql);  
while($row=$db->fetch_array($rs)){  

$path='list12'.$row[id].'.html';  

$fp=fopen("../group/about.html","r");  
$str=fread($fp,filesize("../group/about.html"));  
$str=str_replace("{title}",$row[title],$str);  
$str=str_replace("{name}",$system['name'],$str);  
$str=str_replace("{content}",$row[content],$str);  
$str=str_replace("{copyright}",$system['copyright'],$str);  
fclose($fp);  

$handle=fopen("../group/".$path,"w");   
fwrite($handle,$str);  
echo "<font color='red'>正在生成</font>";  
echo "$path";  
fclose($handle);  
}  
echo "<script>alert('生成成功！');window.location.href='Onlyhtml.php';</script>";
