is_uploaded_file() returns always FALSE

Question

I've created a form for multi-file upload. I report here only the required code, of it.

when I upload one or more files, the array

$_FILES['shopImage']

has the date related the one or more files, and I can see it through the var_dump() I put into the PHP code here below I can spot the uploaded file.

however, the function

is_uploaded_file($_FILES['shopImage']['tmp_name'])

returns always FALSE.

Please here the HTML code that generates the $_FILES array:

<form method="POST" action="upload.php" enctype="multipart/form-data">
...
...
...
    <div class="pics">
        <input type="file" name="shopImage[]">
        <input type="file" name="shopImage[]">
        <input type="file" name="shopImage[]">
        <input type="file" name="shopImage[]">
    </div>
...
...
...
    <input type="submit" name="submit" value="UPDATE"><input type="reset" value="RESET">
</form>

Here the PHP code I used to test it:

<?
require_once $_SERVER['DOCUMENT_ROOT'].'include/setup.php';

if (!empty($_POST['submit']) and $_POST['submit'] == "UPDATE") {

    var_dump($_FILES['shopImage']);
    if(is_uploaded_file($_FILES['shopImage']['tmp_name'])){
        echo "TRUE";
        exit;
    } else {
        echo "FALSE";
        exit;
    }
}
?>

And here here the var_dump()

array(5) {
  ["name"]=>
  array(10) {
    [0]=>
    string(11) "Logo.png"
    [1]=>
    string(0) ""
    [2]=>
    string(0) ""
    [3]=>
    string(0) ""
  }
  ["type"]=>
  array(10) {
    [0]=>
    string(9) "image/png"
    [1]=>
    string(0) ""
    [2]=>
    string(0) ""
    [3]=>
    string(0) ""
  }
  ["tmp_name"]=>
  array(10) {
    [0]=>
    string(14) "/tmp/php2TOmvR"
    [1]=>
    string(0) ""
    [2]=>
    string(0) ""
    [3]=>
    string(0) ""
  }
  ["error"]=>
  array(10) {
    [0]=>
    int(0)
    [1]=>
    int(4)
    [2]=>
    int(4)
    [3]=>
    int(4)
  }
  ["size"]=>
  array(10) {
    [0]=>
    int(21947)
    [1]=>
    int(0)
    [2]=>
    int(0)
    [3]=>
    int(0)
  }
}

NOTE: I did check a quite similar issue here, but the conditions described, are not the same of mine. I didn't implement yet move_upload_file() etc ...

Could you help me please to figure out a solution?

Thanks a lot in advance

As you can see from your var_dump your $_FILES['shopImage']['tmp_name'] is array. So you should check elements of this array, and not the array itself. For example:

foreach ($_FILES['shopImage']['tmp_name'] as $tmp_name) {
    if (is_uploaded_file($tmp_name)) {
        echo 'Yes';
    } else {
        echo 'No';
    }
}
