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');
以上所述就是本文的全部内容了,希望大家能够喜欢。
