Pages which need to be added/modified for complete documentation of PHP 8.3:

Note
This issue is still a Work In Progress

Core

• New features:

    • Readonly Properties can be reinitialized during cloning
  • Override attribute (Add Override Attribute stub #2996)
  • Typed Class constants (Part Update type system documentation #2798)
  • Closures created from magic functions accept named arg
  • final methods on trait
  • Fetch class constant syntax
  • Static Variable Initializer
  • Fallback value syntax for ini variables
• Deprecated
  • Saner Increment/Decrement operators (PHP 8.3: Describe increment/decrement operator changes #2841)
    • Using the increment operator (++) on empty, non-numeric, or non-alphanumeric strings is now deprecated. Moreover, incrementing non-numeric strings is soft deprecated and the new str_increment() function should be used instead.
    • Using the decrement operator (--) on empty or non-numeric strings is now deprecated.
  • get_class()/get_parent_class() call without arguments ([PHP 8.3] Update get_class and get_parent_class #3186)

  • proc_get_status() (Document PHP 8.3 proc_get_status() change #4112)
  • Uses of traits with static properties
  • Assigning a negative index to an empty array
  • Class constant visibility variance check

SAPI

• CLI:
  • It is now possible to lint multiple files. ([PHP 8.3] It is now possible to lint multiple files. #2917)

Extensions

• DateTime:

  • New methods:
    • DatePeriod::createFromISO8601String() (7d81260)
  • New error classes

• DBA:

  • Deprecated:
    • Calling dba_fetch() with $dba as the 3rd argument is now deprecated. ([PHP 8.3] Calling dba_fetch() with $dba as the 3rd argument is now deprecated. #2911)

  • BC Break: (Document DOM BC breaks in 8.3 #2984)
    • Calling DOMChildNode::after(), DOMChildNode::before(), DOMChildNode::replaceWith() on a node that has no parent is now a no-op instead of a hierarchy exception, which is the behaviour demanded by the DOM specification.

    • Calling DOMDocument::createAttributeNS() without specifying a prefix would incorrectly create a default namespace, placing the element inside the namespace instead of the attribute. This bug is now fixed.
    • DOMDocument::createAttributeNS() would previously incorrectly throw a DOM_NAMESPACE_ERRNAMESPACE_ERR DOMException when the prefix was already used for a different URI. It now correctly chooses a different prefix when there's a prefix name conflict.

    • mb_decode_mimeheader() interprets underscores in QPrint-encoded MIME encoded words as required by RFC 2047
    • mb_encode_mimeheader() no longer drops NUL (zero) bytes when QPrint-encoding the input string.

[Girgias]

Note: I did not add the WeakMap, the Zend Max Execution Timers, and the call stack overflowing to the todo list from the BC Break page, as those are engine changes to just make it more sensible.

[TimWolla]

New methods:

• Random\Randomizer::getBytesFromString()
• Random\Randomizer::nextFloat()
• Random\Randomizer::getFloat()

These already have stubs and I've started writing the first bits and pieces of the actual contents.

Somehow looks like #2602 doesn't have any mention in the upgrading document?

Somehow looks like #2602 doesn't have any mention in the upgrading document?

Going by memory. This was a fix for https://bugs.php.net/bug.php?id=47137. I.e. the constant was documented on the libxml constant page, but it didn't work for the DOM save methods. At one point the docs were updated on those save pages to mention only one option worked. When I fixed it, I felt like it was on the border of a fix vs feature request. That combined with the fact it was a non trivial change made me decide to only put the fix in master.

Deprecated:
assertions:
The assert_options() function is now deprecated.
The ASSERT_ACTIVE, ASSERT_BAIL, ASSERT_CALLBACK, ASSERT_EXCEPTION, and ASSERT_WARNING constants have been deprecated.
The assert.* INI settings have been deprecated.

I believe all this has been resolved

Missing the Other Changes page

I've added it.

[haszi]

* [ ]  DOMNameSpaceNode::contains()

I've checked the PHP-8.3.2 branch and the PR that was supposed to add this method but couldn't find DOMNameSpaceNode::contains. Maybe this was added to NEWS accidentally?

[nielsdos]

* [ ]  DOMNameSpaceNode::contains()

I've checked the PHP-8.3.2 branch and the PR that was supposed to add this method but couldn't find DOMNameSpaceNode::contains. Maybe this was added to NEWS accidentally?

Err yes, this method doesn't exist on that class, only on DOMNode. In fact it wouldn't make sense to add it on DOMNameSpaceNode...
So I added this to NEWS by mistake.
