PHP problems with scandir function

Question

dirdel.php:

<?php
//The name of the folder.
$dir = 'images';
//Get a list of all of the file names in the folder.
$arraydir = scandir($dir, 2);
print_r($arraydir);

//Loop through the file list.
foreach ($arraydir as $key => $value) { 
unlink($arraydir[2]); 
}  
?>

Array outputs:

Array ( [0] => . 
        [1] => .. 
        [2] => ana.png 
        [3] => ban.png 
        [4] => ing.png 
        [5] => maca.png 
        [6] => no.png 
        [7] => pret.png )

Warning: unlink(ana.png): No such file or directory in C:\phpdesktop- chrome-57.0-rc-php-7.1.3\www\dirdel.php on line 10

To investigate the error, I also tried something like:

require 'images/';

Output:

Warning: require(C:\phpdesktop-chrome-57.0-rc-php-7.1.3\www\images): failed to open stream: Permission denied in C:\phpdesktop-chrome-57.0-rc- php-7.1.3\www\dirdel.php on line 2

I want to delete the file "ana.png" represented by: "$arraydir[2]" (the file is found in www/images)

I already searched in several places, but I did not find anything, that help me to fix this problem.

Is there any solution for this?

Alternatives are valid, as long as they respect the structure of the arrays:

Array ( [0] => . 
        [1] => .. 
        [2] => ana.png 
        [3] => ban.png 
        [4] => ing.png 
        [5] => maca.png 
        [6] => no.png 
        [7] => pret.png )

Thanks for your attention.

Answer 1

Actually if you run your code you'll always unlink only index 2 of your array. You have to make use of the variables and references that you are using in your foreach loop. I suggest you try the below mentioned code:

<?php
    //The name of the folder.
    $dir = 'images';

    //Get a list of all of the file names in the folder.
    $arraydir = scandir($dir, 2);
    print_r($arraydir);

    //Loop through the file list.
    foreach ($arraydir as $key => $value) {
        if ($arraydir[$key] == 'ana.png' && file_exists($dir . DIRECTORY_SEPARATOR . $arraydir[$key])) {
            unlink($dir . DIRECTORY_SEPARATOR . $arraydir[$key]);
            break;
        } 
    }  
?>

Hope this helps.
