如何检查路径是PHP中的文件或文件夹

Question

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.如何检查路径是否指向文件或文件夹？

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!

Answer 1

看看is_dir()和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';
    }

}
?>
