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