disk_free_space返回目录可用空间,这个可根据你当关硬盘的空间大小来判断
用法

disk_free_space($path);

注: 本函数不能作用于远程文件,被检查的文件必须通过服务器的文件系统访问。

本函数功能

本函数将根据相应的文件系统或磁盘分区返回可用的字节数

好了实例是很简单我们就来看看实例吧.


<?php
$a= disk_free_space("/");
echo $a;
?>

 

 


<?php
// $df 包含根目录下可用的字节数
$df = disk_free_space("/");
//在 Windows 下:
disk_free_space("C:");
disk_free_space("D:");
?>


返回的是文件系统或磁盘分区返回可用的字节数
