Deprecated ✅

• Implicitly nullable parameter (Mention deprecation of implicit nullable types in function docs #4008)

BC Break:

• exit() behavioural changes (PHP 8.4: exit() is now a function #4070)
• Recursion during comparison
• Indirect Modification of readonly Properties
• Temporary Filename Length
• Removal of E_STRICT error level This is an internal engine change

New Functions:

• request_parse_body

New Classes:

• Deprecated (Document #[\Deprecated] #3894)
• RequestParseBodyException

New Constants: ✅

• PHP_OUTPUT_HANDLER_PROCESSED (Update output control constants #3039, Fix GH-3384 #3587)
• PHP_SBINDIR (Add PHP_SBINDIR (PHP-8.4) #3423)

  i.e. if the last path component contained a period.
  In that case, a 404 error was returned.
  The behavior has been changed to look for an index file in all cases.

  • The curl_getinfo() now returns an additional posttransfer_time_us key, containing the number of microseconds from the start until the last byte is sent. When a redirect is followed, the time from each request is added together. This value can also be retrieved by passing CURLINFO_POSTTRANSFER_TIME_T to the curl_getinfo() option parameter. This requires libcurl 8.10.0 or later ([PHP 8.4] Curl new options and constants #4069)

Date:

• Deprecated:

  • DOMImplementation::createDocument() now has a tentative return type of DOMDocument (Document DOMImplementation::createDocument() change for PHP 8.4 #3901)
  • No longer possible to clone DOMXPath objects (Document clone behaviour of DOMXPath #3925)

GMP:

• BC Break:
  • GMP is now final (gmp: GMP is marked final #3990)
• Other Changes:
  • Now possible to cast GMP to bool, before was a E_RECOVERABLE_ERROR

Hash:

• Deprecated:
  • Passing invalid options to hash functions is now deprecated.
• Other changes:
  • hash_update() now has a tentative return type of true instead of bool

Intl:

• Deprecated:
  • Calling intlcal_set() or IntlCalendar::set() with more than 2 arguments is deprecated, use IntlCalendar::setDate() or IntlCalendar::setDateTime() instead.
  • Calling intlgregcal_create_instance() or IntlGregorianCalendar::__construct() with more than 2 arguments is deprecated, use IntlGregorianCalendar::createFromDate() or IntlGregorianCalendar::createFromDateTime() instead.

LDAP:

• Deprecated: (PHP-8.4: LDAP changes #4066)
  • Calling ldap_connect() with more than 2 arguments is deprecated, use ldap_connect_wallet() instead.

  • libxml_set_streams_context() now immediately throws a TypeError when a non-stream-context resource is passed to the function, instead of throwing later when the stream context is used.

MBString:

• BC Break:
  • On invalid strings (those with encoding errors), mb_substr() now interprets character indices in the same manner as most other mbstring functions. This means that character indices returned by mb_strpos() can be passed to mb_substr().
  • For SJIS-Mac (MacJapanese) strings, character indices passed to mb_substr() now refer to the indices of the Unicode codepoints which are produced when the string is converted to Unicode. This is significant because around 40 SJIS-Mac characters convert to a sequence of multiple Unicode codepoints.
• Other changes:
  • The behavior of mb_strcut() is more consistent now on invalid UTF-8 and UTF-16 strings. There is no behavioural change for valid UTF-8 and UTF-16 strings.

• Other changes:
  • The extra_attributes in openssl_csr_new() sets the CSR attributes instead of subject DN, which incorrectly done previously.
  • The dn in openssl_csr_new() allows setting an array of values for a single entry.

[nielsdos]

The TODO lists:

DOMImplementation::getFeature() has been removed

However, this function was never documented and never showed up in the PHP docs, so I guess there's nothing to do here?

Indeed, how convenient. :D

[driade]

Hi, good morning.

May I suggest updating tokens.xml and constants.xml to add T_PUBLIC_SET, T_PROTECTED_SET and T_PRIVATE_SET?

#3936

[iluuu1994]

@Girgias Thank you for working on this! @Crell Do you have any capacity to help out with documentation of our features?

[Crell]

@iluuu1994 Already in progress: #3898, #3828. More to come.

[iluuu1994]

Great to hear, thank you Larry!

[Girgias]

@Ayesh could you look into the cURL docs?

@devnexen could you document the POSIX/Socket/PCNTL/Intl constants?

@bukka can you document the FPM and OpenSSL changes?

@haszi can you document the Output Buffering changes?

@KentarouTakeda (or possibly @devnexen) can you document the PGSQL/PDO_PGSQL changes?

@mbeccati can you document the PDO custom parsers?

@SakiTakamachi can you document the BCMath changes?

@kamil-tekiela can you document the new MySQLi constant, and possibly the MySQLnd changes?

[devnexen]

Sure Gina, will get to it sometime this weekend :)

[Girgias]

@derickr can you document the new DateTime methods?

[mbeccati]

Hey Gina! Not sure exactly what to document about custom parsers atm, but I'll check the current docs and I'll think about something. Perhaps a compatibility list extracted from the RFC page. Cheers

[Ayesh]

Hi @Girgias, thanks for the ping :)
I created #4069 to add all of the missing Curl constants and changes. All of the changes are in separate commits, but in the same PR to prevent potential merge conflicts. I also updated this issue's description with links to the PR. Please do take a look when you get some time. Thank you.

[Ayesh]

I updated the issue text to tick all Curl-related changes. I think that was all of them for Curl.

[nielsdos]

@Ayesh you accidentally wiped my linking, please refresh before making changes

[Ayesh]

@nielsdos I'm so sorry, I will make sure to refresh from now on :(

[nielsdos]

@Ayesh
Dw too much abt it, it's more the fault of GH not auto refreshing properly and being slow to edit a large issue.

[Crell]

Added a link to the WIP hooks doc PR.

[nielsdos]

@Crell I don't know what you did but take a look at your edit history diff, looks like a lot of boxes were unticked and a lot of things were changed.

[Crell]

FFS... I reloaded the page before hitting edit to avoid that!

I don't seem to have access to the history diff. (I'm just a member here, not admin.)

[nielsdos]

Looks like you had an old version cached, and GH doesn't have a "restore old edit" button ffs. See also https://superuser.com/questions/1381271/restore-previous-version-of-my-comment-on-github but I'm on my phone rn...

[Girgias]

I had it saved in my IDE as I got bitten by this already multiple times. So should be fixed now.

[SakiTakamachi]

I am currently creating documentation for the class and new functions regarding bcmath.
