In what ways can PHP developers utilize var_dump($_FILES) to identify and solve path-related problems with file uploads in PHP scripts?

When dealing with file upload issues in PHP scripts, developers can utilize var_dump($_FILES) to inspect the file upload data and identify any path-related problems such as incorrect file paths or permissions. By using var_dump($_FILES), developers can easily see the file upload information, including the file name, file type, file size, and temporary file path.

<?php
if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $uploadDir = 'uploads/';
    $uploadFile = $uploadDir . basename($_FILES['file']['name']);

    if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadFile)) {
        echo "File is valid, and was successfully uploaded.\n";
    } else {
        echo "Possible file upload attack!\n";
    }
} else {
    var_dump($_FILES);
}
?>
