Fedora 38 machine with PHP 8.2.5. Just pulled Phorge; trying to set up a local Phorge test installation.
After locally fixing T15260, I now run into:
```
RuntimeException: strlen(): Passing null to parameter #1 ($string) of type string is deprecated
```
triggered by `getPrefixedCookieName($name)` in https://we.phorge.it/source/phorge/browse/master/src/aphront/AphrontRequest.php .
Should probably replace
`if (strlen($this->cookiePrefix)) {`
with
`if (phutil_nonempty_string($this->cookiePrefix) && strlen($this->cookiePrefix)) {`
or such.
