function mod_rewrite(){
global $_GET;
$nav=?$_SERVER["REQUEST_URI"];
$script_name=?$_SERVER["SCRIPT_NAME"];
$nav=substr(ereg_replace("^$script_name","",urldecode(?$nav)),1);
$nav=preg_replace("/^.ht(m){1}(l){0,1}$/","",$nav);//这句是去掉尾部的.html或.htm
$vars = explode("/",$nav);
for($i=0;$i<Count($vars);$i+=2){
$_GET["$vars[$i]"]=$vars[$i+1];
}
return $_GET;
