| 11 | * Class FilterVarValidateUrl |
| 12 | * |
| 13 | * Since php 8.0, requiring scheme (e.g. the protocol, the "http" part of http://www.somewhere.com) and requiring |
| 14 | * hostname ("www.somewhere.com") have been removed because scheme and hostname have always been required. It is |
| 15 | * possible to configure web servers so that if the scheme is missing, the server will assume a scheme (usually http). |
| 16 | * |
| 17 | * If you look at the documentation for FILTER_VALIDATE_URL, you will see a flag called FILTER_NULL_ON_FAILURE, which |
| 18 | * is meant to tell filter_var to return null instead of false. This class does not support that - the validate method |
| 19 | * returns a pure boolean. |
