What are some common error messages encountered when working with file uploads in PHP?

One common error message when working with file uploads in PHP is "UPLOAD_ERR_INI_SIZE", which indicates that the uploaded file exceeds the upload_max_filesize directive in php.ini. To solve this, you can increase the upload_max_filesize value in your php.ini file or use the ini_set() function in your PHP script to temporarily change the value. 

// Increase upload_max_filesize in php.ini
upload_max_filesize = 20M;
```

Another common error message is "UPLOAD_ERR_FORM_SIZE", which occurs when the uploaded file exceeds the MAX_FILE_SIZE directive in the HTML form. To fix this, you can increase the MAX_FILE_SIZE value in your HTML form.

```php
// Increase MAX_FILE_SIZE in HTML form
<input type="hidden" name="MAX_FILE_SIZE" value="20971520" /> <!-- 20MB -->
