What are some common pitfalls when using the move_uploaded_file function in PHP?

One common pitfall when using the move_uploaded_file function in PHP is not checking if the file was successfully uploaded before moving it. To solve this issue, you should use the is_uploaded_file function to verify that the file was indeed uploaded before attempting to move it. 

if (is_uploaded_file($_FILES['file']['tmp_name'])) {
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
    echo 'File uploaded successfully!';
} else {
    echo 'Error uploading file.';
}
