PHP Array For Each not reading $_POST['item'] data - php

Question

The following code is not
<?php
$deletinglist = addQuotes($_POST['delimglist']);
$deletelist = array($deletinglist);
foreach ($deletelist as $filename) {
unlink(dirname(__FILE__) . "/uploads/" . $filename);
}
function addQuotes($string) {
return '"'. implode('","', explode(',', $string)) .'"';
}
?>
Here $_POST['delimglist'] = "C0d49a7de7b635477125ffffa8df7b932.jpg,C0d49a7de7b635477125ffffa8df7b934.jpg,C0d49a7de7b635477125ffffa8df7b935.jpg";
If I use $deletelist = array("C0d49a7de7b635477125ffffa8df7b932.jpg","C0d49a7de7b635477125ffffa8df7b934.jpg","C0d49a7de7b635477125ffffa8df7b935.jpg");
Its working fine but if I use $deletelist = array($deletinglist); its not working.
I am getting the following Warning when trying to use like the above
Warning: unlink(/home/...somepath.../uploads/"C0d49a7de7b635477125ffffa8df7b932.jpg","C0d49a7de7b635477125ffffa8df7b934.jpg","C0d49a7de7b635477125ffffa8df7b935.jpg"): No such file or directory in /home/...somepath.../deletefile.php on line 9

Answer 1

I'm not sure why do you add quotes around filename?
The code should be as simple as this:
<?php
$deletelist = explode(',', $_POST['delimglist']);
foreach ($deletelist as $filename) {
unlink(dirname(__FILE__) . "/uploads/" . $filename);
}
?>

Answer 2

All you're doing is putting $deleteList into an array as a single element. You want to separate the values by ','. Use $deleteList = explode(',', $deleteList);

Answer 3

The following are not the same thing:
$arr1 = Array("a", "b", "c");
$str = "a,b,c";
$arr2 = Array($str);
The commas in the first example are a language construct: writing them inside a single variable does not mean they magically gain language construct abilities; inside the string they are just characters.
Similarly, this:
$str = "a,b,c";
foo($str);
is the same as this:
foo("a,b,c");
and not this:
foo("a", "b", "c");
You will have to use a function that explicitly splits up the string $_POST['delimglist']:
$deleteList = explode(',', $_POST['delimglist']);
