PHP define the destination folder for an upload - php

Question

I use the following PHP script to upload an image to my server. Actually it moves the file in the same folder where my script is (root). I would like to move it into the folder root/imageUploads. Thank you for your hints!
$source = $_FILES["file-upload"]["tmp_name"];
$destination = $_FILES["file-upload"]["name"];
...
if ($error == "") {
if (!move_uploaded_file($source, $destination)) {
$error = "Error moving $source to $destination";
}
}

Answer 1

You will need to check if the destination folder exists.
$destination = $_SERVER['DOCUMENT_ROOT'] . '/imageUploads/'
if (! file_exists($destination)) { // if not exists
mkdir($destination, 0777, true); // create folder with read/write permission.
}
And then try to move the file
$filename = $_FILES["file-upload"]["name"];
move_uploaded_file($source, $destination . $filename);

Answer 2

So now your destination looks like this:
some-file.ext
and it's dir is same as file that executes it.
You need to append some dir path to current destination. E.g.:
$path = __DIR__ . '/../images/'; // Relative to current dir
$path = '/some/path/in/server/images'; // Absolute path. Start with / to mark as beginning from root dir
And then move_uploaded_file($source, $path . $destination)

Answer 3

Full path to the destination folder should be provided to avoid and path issue for moving uploaded files, I have added three variations for destination paths below
$uploadDirectory = "uploads";
// Gives the full directory path of current php file
$currentPath = dirname(__FILE__);
$source = $_FILES["file-upload"]["tmp_name"];
// If uploads directory exist in current folder
// DIRECTORY_SEPARATOR gices the directory seperation "/" for linux and "\" for windows
$destination = $currentPath.DIRECTORY_SEPARATOR.$uploadDirectory.DIRECTORY_SEPARATOR.$_FILES["file-upload"]["name"];
if (!move_uploaded_file($source, $destination)) {
echo $error = "Error moving $source to $destination";
}
// If to current folder where php script exist
$destination = $currentPath.DIRECTORY_SEPARATOR.$_FILES["file-upload"]["name"];
if (!move_uploaded_file($source, $destination)) {
echo $error = "Error moving $source to $destination";
}
// If uploads directory exist outside current folder
$destination = $currentPath.DIRECTORY_SEPARATOR."..".DIRECTORY_SEPARATOR.$uploadDirectory.DIRECTORY_SEPARATOR.$_FILES["file-upload"]["name"];
if (!move_uploaded_file($source, $destination)) {
echo $error = "Error moving $source to $destination";
}
