How can the PHP documentation on file uploads help in resolving issues related to passing files from HTML to PHP?

Issue: When passing files from HTML to PHP, it is important to correctly set the enctype attribute of the form to "multipart/form-data" to ensure that files are properly uploaded and accessible in PHP.

```php
<form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Upload File">
</form>
```

By setting the enctype attribute to "multipart/form-data" in the HTML form, files can be successfully uploaded and accessed in PHP using the $_FILES superglobal array. This ensures that the file data is properly passed from the HTML form to the PHP script for processing.
