<?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");$f = fopen('data','r');//读取多行数据 whilewhile(!feof($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()：
