Can we limit the #ifdeferry to the nxt_php_disable() function itself?

[andypost]

Yes, it could be cleaner to limit ifdef to the function only but there's no zend structure anymore so yoou need to change calling code anyway.

src/nxt_php_sapi.c:715:33: error: use of undeclared identifier 'zend_disable_class'

Another option could be deprecation of disable_classes in php mod as it will be removed in php 9 anyway so this setting will gone someday...

So ATM it's not clear which way is preferable, moreover disabled_functions also full of ifdeffery(

[ac000]

It was just a thought.

I will probably squeeze this into 1.35.0 (which is likely to be the
final release for the foreseeable future...)
