How can someone with limited PHP knowledge effectively incorporate an upload feature into their PHP forum?

To incorporate an upload feature into a PHP forum with limited PHP knowledge, the individual can use a simple HTML form to allow users to select and upload files. They can then use PHP to handle the file upload process, including checking file types, sizes, and moving the uploaded file to a designated folder on the server. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_FILES["file"])) {
    $target_dir = "uploads/";
    $target_file = $target_dir . basename($_FILES["file"]["name"]);

    if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {
        echo "The file has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">
    Select file to upload:
    <input type="file" name="file" id="file">
    <input type="submit" value="Upload File" name="submit">
</form>
