### Description
It seems that anonymous class names change based on the opcache status of the PHP file that includes
the anonymous class declaration. Here is an example:
```php
<?php // A.php
var_dump(get_class(require 'B.php'));
var_dump(get_class(require 'B.php'));
var_dump(get_class(require 'B.php'));
var_dump(get_class(require 'B.php'));
<?php // B.php
return new class {};
```
Resulted in this output:
```
# First Scenario "Without opcache":
➜ php -d "opcache.enable_cli"=0 A.php
/Users/nunomaduro/demo/A.php:3:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$5"
/Users/nunomaduro/demo/A.php:4:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$6"
/Users/nunomaduro/demo/A.php:5:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$7"
/Users/nunomaduro/demo/A.php:6:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$8"
```
```
# Second Scenario "With opcache" (and after running the script once, so the file gets
cached)
➜ php -d "opcache.enable_cli"=1 A.php
/Users/nunomaduro/demo/A.php:3:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$5"
/Users/nunomaduro/demo/A.php:4:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$5"
/Users/nunomaduro/demo/A.php:5:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$5"
/Users/nunomaduro/demo/A.php:6:
string(48) "class@anonymous\000/Users/nunomaduro/demo/B.php:3$5"
```
It's unclear to me whether the "expected" output should correspond to the first or
the second scenario. However, the fact that the generated class names vary depending on the opcache
status of the file is what prompted me to create the issue.
