It needs to be "object".
This is because first- and third-party extension can register custom
node types using `php_libxml_register_export`. So we don't know upfront
what types can be expected.
This also changes the error to a TypeError everywhere.
In master I use ZEND_DIAGNOSTIC_IGNORED_START, but that doesn't exist on
8.2 or 8.3 (8.3 has a similar macro though).
So to unbreak CI I just made a variation of this directly in the
php_libxml.h header.

* Define doXInclude for XSLTProcessor, and test the property
This was added in 8d1427dd98, but never defined on the stub.
It was more or less fine when dynamic properties were not deprecated,
but now they throw a deprecation warning. To fix it, define on the stub.
This should also help discoverability of the functionality.
* Define cloneDocument for XSLTProcessor, and test the property
This was introduced in 5c039bbad9, but never defined on the stub.

This reimplements the parameter handling. Instead of quoting the strings
manually, adding them to an array, and passing that as input; use the
libxslt API to pass data verbatim to the processor.
This also simplifies the code a lot.
Closes GH-12331.
* PHP-8.2:
Fix GH-10008: Narrowing occurred during type inference of ZEND_ADD_ARRAY_ELEMENT
Fix type error on XSLTProcessor::transformToDoc return value with SimpleXML
* PHP-8.1:
Fix GH-10008: Narrowing occurred during type inference of ZEND_ADD_ARRAY_ELEMENT
Fix type error on XSLTProcessor::transformToDoc return value with SimpleXML
The return type is wrong. You can also use this method with SimpleXML.
In fact, PHP provides a way that even third party libraries can hook
into its XML handling. Therefore, we cannot even use the
SimpleXML|DOMDocument|false union type as third party extensions may
extend the possibilities.
Broke in 8.1 in 1b35056a33.
Closes GH-12315.
We may OOM during object initialization. In this case, free_obj needs to guard
against NULL values. There may be more cases where this is an issue, these were
the ones I was able to discover via script.
Fixes GH-11734

To parse a document with libxml2, you first need to create a parsing context.
The parsing context contains parsing options (e.g. XML_NOENT to substitute
entities) that the application (in this case PHP) can set.
Unfortunately, libxml2 also supports providing default set options.
For example, if you call xmlSubstituteEntitiesDefault(1) then the XML_NOENT
option will be added to the parsing options every time you create a parsing
context **even if the application never requested XML_NOENT**.
Third party extensions can override these globals, in particular the
substitute entity global. This causes entity substitution to be
unexpectedly active.
Fix it by setting the parsing options to a sane known value.
For API calls that depend on global state we introduce
PHP_LIBXML_SANITIZE_GLOBALS() and PHP_LIBXML_RESTORE_GLOBALS().
For other APIs that work directly with a context we introduce
php_libxml_sanitize_parse_ctxt_options().
Upon freeing libxslt's context, every document which is not the *main*
document will be freed by libxslt. If a node of a document which is not
the main document gets returned to userland, we'd free the node twice:
- first by the cleanup of the xslt context
- and then by our own refcounting mechanism.
This was reported in bug 49634, and was fixed by always copying the
node (and later re-fixed in bug 70078).
The original fix is not entirely correct unfortunately because of the
following two main reasons:
- modifications to the node will only modify the copy, and not the original
- accesses to the parent, path, ... will not work
This patch fixes it properly by only copying the node if it origins from
a document other than the main document.

This reverts commit 94ee4f9834.
The commit was a bit too late to be included in PHP 8.2 RC1. Given it's a massive ABI break, we decide to postpone the change to PHP 8.3.
- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
