写入文本文件txt的PHP代码
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"]; |
