PHP scandir not working for relative path

Question

I have a folder called images in my current directory but when I try to run the code below I get the following error:

PHP Warning: scandir(../images,../images): The system cannot find the file specified. (code: 2) in C:\Program Files (x86)\Ampps\www\dev\php\recolor_png\dir.php on line 4

<?php
$dir = "../images";

$a = scandir($dir);

print_r($a);

I've tried every variation of the path I can think of (images, /images/, "images", 'images' etc. but no joy.

var_dump (is_dir('/images')); also gives false

Please help?

Answer 1

I think your $dir is not correct.you can use

$dir = __DIR__ . "/images";

or

$dir = "./images";

Both are working. If its not working show me your image folder structure.

Answer 2

Try to use __DIR__ constant

$dir = __DIR__ . "/images";
