在php中我们要删除一个指定的文件我们可以使用unlink函数来实现,下面我给大家详细介绍unlink函数删除一个指定文件的具体方法,有需要了解的朋友可参考参考。

unlink() 函数删除文件。

若成功,则返回 true,失败则返回 false。

 代码如下 复制代码

unlink("test.txt");
?>

 代码如下 复制代码

$file = "test.txt";if (!unlink($file))  {
 echo ("Error deleting $file");  }else  { 
echo ("Deleted $file");  }
?>

加上判断

 代码如下 复制代码

$file = "test.txt";
if(unlink($file))
{
  echo "文件 $file 删除成功!";
}
else
{
  echo "文件 $file 删除失败!";
}
?>
