PHP文件操作方法汇总
这篇文章主要介绍了PHP文件操作方法汇总的相关资料,需要的朋友可以参考下
在data文件中写入数据:
- <?php
- /**
- * Created by PhpStorm.
- * User: Administrator
- * Date: 2015/6/29
- * Time: 17:05
- */
- header("Content-type: text/html; charset=utf-8");
- //write data
- $f = fopen('data','w');//打开文件
- fwrite($f,'Hello PHP');//写入数据
- fclose($f);//关闭文件
- echo 'OK';
- //windows环境暂时不考虑权限问题
写入成功后可以在页面看到“OK”,接下来读取data文件里的数据
- <?php
- /**
- * Created by PhpStorm.
- * User: Administrator
- * Date: 2015/6/29
- * Time: 17:05
- */
- header("Content-type: text/html; charset=utf-8");
- //read data
- $f = fopen('data','r');
- $content = fgets($f);
- echo $content;
- fclose($f);
如果有多行数据该怎么读取?
方法一 while:
- <?php
- /**
- * Created by PhpStorm.
- * User: Administrator
- * Date: 2015/6/29
- * Time: 17:05
- */
- header("Content-type: text/html; charset=utf-8");
- $f = fopen('data','r');
- //读取多行数据 while
- while(!feof($f)){//feof() 函数检测是否已到达文件末尾
- $content = fgets($f);
- echo $content;
- }
- fclose($f);
方法二 file_get_contents():
echo file_get_contents('data');
