扩展应用,比如记录每次请求的url内容
function writeGetUrlInfo()
{
//获取请求方的地址,客户端,请求的页面及参数
$requestInformation = $_SERVER['REMOTE_ADDR'].', '.$_SERVER['HTTP_USER_AGENT'].', http://'.$_SERVER['HTTP_HOST'].htmlentities ($_SERVER['PHP_SELF']).'?'.$_SERVER['QUERY_STRING']."\n";
$fileName = RootPath.'/log/'.date('Y-m-d').'.log'; //网站根目录RootPath是在配置文件里define('RootPath', substr(dirname(__FILE__)));
writeFile($fileName, $requestInformation, 'a'); //表示追加
}
orther Eg:
$date = date("Y-m-d",time());
$time = date('H:i:s',time());
$dir = root."data/GamePay/{$paycord}/";
isdir($dir,0777);
$payfile = $dir."pay_$date.log";
$fp = @fopen($payfile,'a+');
if($fp){
@fwrite($fp,"$date $time member_id:$member_id\n");
@fwrite($fp,"$date $time username:$username\n");
@fwrite($fp,"$date $time order_id:$order_id"\n");
@fwrite($fp,"$date $time gold:$gold\n");
@fwrite($fp,"$date $time url:$url\n\n");
fclose($fp);
}
