推荐答案
我相信问题在于您正在打开目录，而对句柄没有任何处理.相反，您可以尝试使用scandir()，这将导致目录中的文件数组而不是目录对象.
I believe the problem is that you're opening a directory and not doing anything with the handle. You might instead try using scandir() which will result in an array of the files in the directory, instead of a directory object.
您可以尝试执行以下操作:
you might try something like this:
...
is_dir($categorydir[$_POST['category']])){
$files = scandir($categorydir[$_POST['category']]);
}else{
echo 'target directory not found';
}
echo 'Results of search:<br></br>';
foreach($files as $file){
echo($file);
}
