1. 写入:

<&#63;php 
$filename = "Test//file.txt"; 
$file = fopen($filename, "w"); //以写模式打开文件 
fwrite($file, "Hello, world!/n"); //写入第一行 
fwrite($file, "This is a test!/n"); //写入第二行 
fclose($file); //关闭文件 
&#63;> 

2. 删除:

<&#63;php 
$filename = "Test//file.txt"; 
unlink($filename); //删除文件 
&#63;> 

3.复制:

<&#63;php 
$filename1 = "Test//file.txt";
