換行有關問題

換行問題
$fp = fopen("log.txt","a ");
fwrite($fp,date("Y-m-d H:i:s"));
fwrite($fp," ");
fwrite($fp,$_SERVER[REMOTE_ADDR]);
fwrite($fp," ");
fwrite($fp,$_SERVER[HTTP_X_REWRITE_URL]);
fwrite($fp," ");
fwrite($fp,$_SERVER[HTTP_USER_AGENT]);
fwrite($fp," ");
fwrite($fp,$_SERVER["HTTP_REFERER"]);
fwrite($fp," ");
fclose($fp);
?>

這個是記錄訪問者ip的。怎麼讓寫在txt裡面換行啊，這是在一行顯示的

------解決方案--------------------
在每個要換行的地方加入分行符號就可以了。
fwrite($fp,"\t\r\n");
------解決方案--------------------

PHP code

$fp = fopen("log.txt","a ");fwrite($fp,date("Y-m-d H:i:s").PHP_EOL); //用PHP_EOL換行吧，跨平台的
------解決方案--------------------
PHP.EOL 和 \n都行的
------解決方案--------------------
fwrite($fp," ");
改為
fwrite($fp,PHP_EOL);
