写入文本文件txt的PHP代码

Jun 13, 2016 am 11:26 AM
php txt consistent code write function and document text use of language read

PHP写入文本文件和C语言非常类似,用的函数也一致,读取文件用fopen,写入文件用fwrite,结束用fclose。要注意的是打开并写入新的文件用"w"标识,读取文件用"r"标识,在原有文件上继续写入用"a"标识

,同时windows换行符是"rn",linux换行符是"n"
    PHP记录IP的函数是 $_SERVER["REMOTE_ADDR"]

    PHP获取当前时间函数date("Y-m-d H:i:s", time())

    PHP获取来路网址函数$_SERVER['HTTP_REFERER'] 首先要判断其是否为空值,即用isset进行判断,比如我们直接从浏览器敲入网址则不会有来路网址记录,最后代码很简单,如下:

 代码如下 复制代码

$ip = $_SERVER["REMOTE_ADDR"];
$time = date("Y-m-d H:i:s", time());
$from = '';
if(isset($_SERVER['HTTP_REFERER']))
{
   $from = $_SERVER['HTTP_REFERER'];
}
$myfile = 'wtndata/statistic.txt';
$str = "ip='".$ip."' from='".$from."' time='".$time."'rn";
$file_pointer = fopen($myfile,"a");
fwrite($file_pointer,$str);
fclose($file_pointer);
