PHP Core

<?php
$result = "Hello World" |> strlen(...);
print $result . PHP_EOL;  // Prints "11"

<?php

#[\NoDiscard]
function concat(string $a, string $b): string {
     return $a . $b;
}

// Warning: The return value of function concat() should either be used or
// intentionally ignored by casting it as (void) in xxx.php
concat("a", "b");

// No warning, because the return value is consumed by the assignment.
$results = concat("a", "b");

// No warning, because the (void) cast is used.
(void)concat("a", "b");

<?php
const T1 = (int) 0.3; // Previously: "Fatal error: Constant expression contains invalid operations"
print T1 . PHP_EOL;   // Prints "0"

cURL

Added support for share handles that are persisted across multiple PHP requests, safely allowing for more effective connection reuse.

Added support for CURLINFO_USED_PROXY (libcurl >= 8.7.0), CURLINFO_HTTPAUTH_USED, and CURLINFO_PROXYAUTH_USED (libcurl >= 8.12.0) to the curl_getinfo() function. When curl_getinfo() returns an array, the same information is available as "used_proxy", "httpauth_used", and "proxyauth_used" keys. CURLINFO_USED_PROXY gets zero set if no proxy was used in the previous transfer or a non-zero value if a proxy was used. CURLINFO_HTTPAUTH_USED and CURLINFO_PROXYAUTH_USED get bitmasks indicating the HTTP and proxy authentication methods that were used in the previous request. See CURLAUTH_* constants for possible values.

Added CURLOPT_INFILESIZE_LARGE Curl option, which is a safe replacement for CURLOPT_INFILESIZE. On certain systems, CURLOPT_INFILESIZE only accepts a 32-bit signed integer as the file size (2.0 GiB) even on 64-bit systems. CURLOPT_INFILESIZE_LARGE accepts the largest integer value the system can handle.

Added CURLFOLLOW_OBEYCODE, CURLFOLLOW_FIRSTONLY and CURLFOLLOW_ALL values for CURLOPT_FOLLOWLOCATION curl_setopt() option. CURLFOLLOW_OBEYCODE to follow more strictly in regard to redirect if they are allowed. CURLFOLLOW_FIRSTONLY to follow only the first redirect thus if there is any follow up redirect, it won't go any further. CURLFOLLOW_ALL is equivalent to setting CURLOPT_FOLLOWLOCATION to true.

Added support for CURLINFO_CONN_ID (libcurl >= 8.2.0) to the curl_getinfo() function. This constant allows retrieving the unique ID of the connection used by a cURL transfer. It is primarily useful when connection reuse or connection pooling logic is needed in PHP-level applications. When curl_getinfo() returns an array, this value is available as the "conn_id" key.

Added support for CURLINFO_QUEUE_TIME_T (libcurl >= 8.6.0) to the curl_getinfo() function. This constant allows retrieving the time (in microseconds) that the request spent in libcurl’s connection queue before it was sent. This value can also be retrieved by passing CURLINFO_QUEUE_TIME_T to the curl_getinfo() option parameter.

Added support for CURLOPT_SSL_SIGNATURE_ALGORITHMS to specify the signature algorithms to use for TLS.

DOM

Added Dom\Element::$outerHTML.

Added $children property to Dom\ParentNode implementations.

EXIF

Added support for OffsetTime* Exif tags.

Added support for HEIF/HEIC.

Filter

Added new FILTER_THROW_ON_FAILURE flag which can be passed to the filter functions and will force an exception to be triggered when validation fails. The new flag cannot be combined with FILTER_NULL_ON_FAILURE; trying to do so will result in a ValueError being thrown.

Intl

Added class constants NumberFormatter::CURRENCY_ISO, NumberFormatter::CURRENCY_PLURAL, NumberFormatter::CASH_CURRENCY, and NumberFormatter::CURRENCY_STANDARD for various currency-related number formats.

Added Locale::addLikelySubtags() and Locale::minimizeSubtags() to handle likely tags on a given locale.

Added IntlListFormatter class to format, order, and punctuate a list of items with a given locale, IntlListFormatter::TYPE_AND, IntlListFormatter::TYPE_OR, IntlListFormatter::TYPE_UNITS operands and IntlListFormatter::WIDTH_WIDE, IntlListFormatter::WIDTH_SHORT and IntlListFormatter::WIDTH_NARROW widths. It is supported from icu 67.

PDO_Sqlite

Added class constant Pdo\Sqlite::ATTR_BUSY_STATEMENT.

Added class constants Pdo\Sqlite::ATTR_EXPLAIN_STATEMENT, Pdo\Sqlite::EXPLAIN_MODE_PREPARED, Pdo\Sqlite::EXPLAIN_MODE_EXPLAIN, Pdo\Sqlite::EXPLAIN_MODE_EXPLAIN_QUERY_PLAN.

Added Pdo\Sqlite::ATTR_TRANSACTION_MODE connection attribute with possible values Pdo\Sqlite::TRANSACTION_MODE_DEFERRED, Pdo\Sqlite::TRANSACTION_MODE_IMMEDIATE, and Pdo\Sqlite::TRANSACTION_MODE_EXCLUSIVE, allowing to configure the transaction mode to use when calling beginTransaction().

Session

session_set_cookie_params(), session_get_cookie_params(), and session_start() now support partitioned cookies via the "partitioned" key.

SOAP

Enumeration cases are now dumped in SoapClient::__getTypes().

Added support for Soap 1.2 Reason Text xml:lang attribute.

The signature of SoapFault::__construct() and SoapServer::fault() therefore now have an optional lang parameter. This support solves compatibility with .NET SOAP clients.

Standard

mail() now returns the actual sendmail error and detects if the sendmail process was terminated unexpectedly. In such cases, a warning is emitted and the function returns false. Previously, these errors were silently ignored. This change affects only the sendmail transport.

getimagesize() now supports HEIF/HEIC images.

getimagesize() now supports SVG images when ext-libxml is also loaded. Similarly, image_type_to_extension() and image_type_to_mime_type() now also handle IMAGETYPE_SVG.

The array returned by getimagesize() now has two additional entries: "width_unit" and "height_unit" to indicate in which units the dimensions are expressed. These units are px by default. They are not necessarily the same (just to give one example: one may be cm and the other may be px).

setcookie() and setrawcookie() now support the "partitioned" key.

URI

An always enabled uri extension is added that can be used for handling URIs and URLs according to RFC 3986 and WHATWG URL.

XSL

The namespace argument of XSLTProcessor::getParameter(), XSLTProcessor::setParameter() and XSLTProcessor::removeParameter() now actually works instead of being treated as empty. This only works if the name argument does not use Clark notation and is not a QName because in those cases the namespace is taken from the namespace href or prefix respectively.

Zlib

flock() is now supported on zlib streams. Previously, this always failed to perform any locking action.
