Fataling if `::__debugInfo()` doesn't return an array appears to be overly restrictive; we can handle that like returning null, namely by throwing an `Error` exception and returning an empty array instead.

Need to check the failing tests. |

zend_print_zval_r_to_buf didn't check for EG(exception) before, so I'm assuming it's probably fine not to start checking for EG(exception) (e.g. __debugInfo manually throwing, e.g. in a destructor in a local scope after return [];).
But it might be intuitive to stop IS_ARRAY/IS_OBJECT loops anyway if there is an exception?
It may be useful to test partial output behavior for throwing in nested values?

Possibly no longer needed if switch is comprehensive, haven't tested.

Not familiar enough with this code to be sure: Does this code predate zend_empty_array (which would be non-reference-counted and have to have *is_temp = 0)
#define ZVAL_EMPTY_ARRAY(z) do { \
zval *__z = (z); \
Z_ARR_P(__z) = (zend_array*)&zend_empty_array; \
Z_TYPE_INFO_P(__z) = IS_ARRAY; \
} while (0)

Does this need to be thrown if EG(exception) is already non-null after the call? It seems more intuitive (for userland expectations) to have the original exception than to replace it.

@cmb69 can you please reopen this PR or is there any big issue with the impl? |
|
There have been failing tests, and @TysonAndre's comments need to be addressed. I currently don't have time for this. Feel free to take over the patch, and submit a new PR. |

Sadly, my knowledge of php internals is limited :( |
|
@cmb69 when I will address the comments, can it target PHP 8.0 as a bugfix? |
New features should always target master. |

Errorexception and returning an empty array instead.PS: if null is returned, we don't throw an exception like before. Exception is only thrown if not array|null.
