This question already has an answer here:
Trying to make a uploads correct. But when using var_dump on my upload folder there are two dots by default ['.', '..'] . What could be causing this ?
<?php
$render = '';
$filenames = '';
$dir = './upload';
$aFilenames = scandir($dir);
if(isset($_FILES["file"]["error"]) > 1){
echo "Error: ".$_FILES["file"]["error"]."<br />";
} elseif (isset($_FILES["file"]["name"])) {
$filename = basename($_FILES['file']['name']);
move_uploaded_file($_FILES['file']['tmp_name'],'upload/'.$filename);
$render .= "name file: " .$_FILES['file']['name'] .'<br>';
$render .= "type file: " .$_FILES['file']['type'] .'<br>';
$render .= "size: " .($_FILES['file']['size']/1024) .'kb <br>';
$render .= "saved in: " .$_FILES['file']['tmp_name'] .'<br>';
$render .= '<img src="upload/'.$_FILES['file']['name'].'" height="40px">';
}
else {
echo 'Upload a file';
}
foreach ($aFilenames as $key) {
$filenames .= $key . '<br>';
}
var_dump($aFilenames);
?>
Thanks in advance !

That's the parent directory and the previous directory
You can see this behavior also, when you do a simple directory structure listing in cmd:
C:\data>dir
Volume in drive C has no label.
Volume Serial Number is CEAE-5F97
Directory of C:\data
12.01.2017 17:02 .
12.01.2017 17:02 ..
27.12.2016 11:10 db
08.12.2016 14:46 keys
01.12.2016 11:08 531 368 putty.exe
11.01.2017 13:00 www
1 File(s) 531 368 bytes
5 Dir(s) 133 482 266 624 bytes free
You can just unset those values, when using directory scans.
