在data文件中写入数据:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
|
<?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:
1
2
3
4

<?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' ); |
