如何检查路径是PHP中的文件还是文件夹
问题描述：
我使用scandir()递归搜索文件.但是，如果文件路径指向文件而不是文件夹，则会出现警告.如何检查路径是直接引导文件还是文件夹?
I use scandir() to search files recursively. But if the file path directs to a file not a folder, there will be a warning. How can I check the path whether it directs a file or folder?
enter code here
<?php
$path = "C:\\test_folder\\folder2\\folder4";
$sub_folder = scandir($path);
$num = count($sub_folder);
for ($i = 2; $i < $num; $i++)
{
...//if $sub_folder[$i] is a file but a folder, there will be a warning.
How can I check $sub_folder[$i] before use it?
}
?>
谢谢！
答
看看is_dir()和is_file()
Have a look into is_dir() and is_file()
<?php
$path = "C:\\test_folder\\folder2\\folder4";
$sub_folder = scandir($path);
$num = count($sub_folder);
for ($i = 2; $i < $num; $i++)
{
if(is_file($path.'\\'.$sub_folder[$i])){
echo 'Warning';
}
}
?>
