The high resolution timer (hrtime()) on macOS now
uses the recommended
clock_gettime_nsec_np(CLOCK_UPTIME_RAW) API instead of
mach_absolute_time().
The -z or --zend-extension option has been removed as it was non-functional. Use -d zend_extension=[path] instead.
The fetch behaviour for larger columns has been changed. Rather than fetching 256 byte blocks, PDO_ODBC will try to fetch a larger block size; currently, this is the page size minus string overhead. Drivers that return SQL_NO_TOTAL in SQLGetData are also better handled as well. This should improve compatibility and performance.
Trying to set a process title that is too long with cli_set_process_title() will now fail instead of silently truncating the given title.
Added a new --ini=diff option to print INI settings changed from the builtin default.
FPM with httpd ProxyPass optionally decodes the full script path. Added fastcgi.script_path_encoded INI setting to prevent this new behavior.
FPM access log limit now respects log_limit value.
grapheme_extract() properly assigns
$next value when skipping over invalid starting bytes.
Previously there were cases where it would point to the start of the
grapheme boundary instead of the end.
transliterator_get_error_code(),
transliterator_get_error_message(),
TransLiterator::getErrorCode(),
and TransLiterator::getErrorMessage()
have dropped false from the return type union. Returning false
was actually never possible.
The following functions now support a $locale argument:
grapheme_strpos(),
grapheme_stripos(),
grapheme_strrpos(),
grapheme_strripos(),
grapheme_substr(),
grapheme_strstr() and
grapheme_stristr()
ldap_get_option() now accepts a null connection,
like ldap_set_option(), to allow retrieval of global
options.
libxml_set_external_entity_loader() now has a formal return type of true.
openssl_public_encrypt() and
openssl_private_decrypt() have a new parameter
$digest_algo that allows specifying the hash
digest algorithm for OAEP padding.
openssl_sign() and openssl_verify()
have a new parameter $padding to allow using more
secure RSA PSS padding.
openssl_cms_encrypt() $cipher_algo
parameter can be a string with the cipher name.
That allows to use more algorithms including AES GCM cipher algorithms for
auth enveloped data.
pcntl_exec() now has a formal return type of false.
pcntl_waitid() takes an additional resource_usage argument to gather various platform specific metrics about the child process.
Pdo\Pgsql::copyFromArray() now supports iterable inputs.
Pdo\Pgsql::setAttribute() and
Pdo\Pgsql::prepare() support setting
PDO::ATTR_PREFETCH to 0 which enters lazy fetch mode.
In this mode, statements cannot be run in parallel.
pg_copy_from() now supports iterable inputs.
pg_connect() checks if the connection_string argument contains any null byte.
pg_close_stmt() checks if the statement_name argument contains any null byte.
posix_ttyname() sets last_error to EBADF when encountering an invalid file descriptor.
posix_isatty() raises an E_WARNING
message when encountering an invalid file descriptor.
posix_fpathconf() checks invalid file descriptors and
sets last_error to EBADF and raises an E_WARNING message.
The output of ReflectionClass::__toString() for enums has changed to better indicate that the class is an enum, and that the enum cases are enum cases rather than normal class constants.
The output of ReflectionProperty::__toString() for properties with hooks has changed to indicate what hooks the property has, whether those hooks are final, and whether the property is virtual. This also affects the output of ReflectionClass::__toString() when a class contains hooked properties.
socket_create()/socket_bind() can
create AF_PACKET family sockets.
socket_getsockname() gets the interface index and its
string representation with AF_PACKET socket.
The $use_include_path argument for the
gzfile(), gzopen() and
readgzfile() functions has been changed
from int to boolean.
gzfile(), gzopen() and readgzfile() functions now respect the default stream context.
curl_setopt() with
CURLOPT_FOLLOWLOCATION option's value
no longer is treated as boolean but integer to handle
CURLFOLLOW_OBEYCODE and
CURLFOLLOW_FIRSTONLY.
Upgraded file from 5.45 to 5.46.
The return type of finfo_close() has been changed to true, rather than bool.
Intl's internal error mechanism has been modernized so that it indicates more accurately which call site caused what error. Moreover, some ext/date exceptions have been wrapped inside a IntlException now.
An always enabled lexbor extension is added. It contains the lexbor library that was separated from ext/dom for being reused among other extensions. The new extension is not directly exposed to userland.
The Opcache extension is now always built into the PHP binary and is always loaded. The INI directives opcache.enable and opcache.enable_cli are still honored.
Upgraded pcre2lib from 10.44 to 10.46.
Increased minimum release version support from 3.7.7 to 3.7.17.
The return types of readline_add_history(), readline_clear_history(), and readline_callback_handler_install() have been changed to true, rather than bool.
ReflectionConstant is no longer final.
Added fatal_error_backtraces to control whether fatal errors should include a backtrace.
Added startup-only max_memory_limit INI setting to control the maximum memory_limit that may be configured at startup or runtime. Exceeding this value emits a warning, unless set to -1, and sets memory_limit to the current max_memory_limit instead.
Added opcache.file_cache_read_only to support a read-only
opcache.file_cache directory,
for use with read-only file systems (e.g. read-only Docker containers).
Best used with opcache.validate_timestamps=0,
opcache.enable_file_override=1,
and opcache.file_cache_consistency_checks=0.
Nota: A cache generated with a different build of PHP, a different file path, or different settings (including which extensions are loaded), may be ignored.
The default value of opcache.jit_hot_loop is now 61 (a prime) to prevent it from being a multiple of loop iteration counts. It is recommended that this parameter is set to a prime number.
Changing opcache.memory_consumption when OPcache SHM is already set up will now correctly report a failure instead of silently doing nothing and showing misleading values in PHPInfo.
Added openssl.libctx to select the OpenSSL library context type. Either custom libctx for each thread can be used or a single global (default) libctx is used.
Remove OPcodes for identity comparisons against booleans, particularly
for the match(true) pattern.
Add OPcode specialization for === [] and
!== [] comparisons.
Creating exception objects is now much faster.
The parts of the code that used SSE2 have been adapted to use SIMD with ARM NEON as well.
Introduced the TAILCALL VM, enabled by default when compiling with Clang>=19 on x86_64 or aarch64. The TAILCALL VM is as fast as the HYBRID VM used when compiling with GCC. This makes PHP binaries built with Clang>=19 as fast as binaries built with GCC. The performance of the CALL VM, used with other compilers, has also improved considerably.
Now avoids creating extra string copies when converting strings for use in the collator.
The parts of the code that used SSE2 have been adapted to use SIMD with ARM NEON as well.
Improved performance of fetching TLS variables in JIT'ed code in non-Glibc builds.
Improved performance of the following methods:
Improved performance of dimension accessors and methods of SplFixedArray.
Improved performance of array functions with callbacks (array_find(), array_filter(), array_map(), usort(), ...).
Improved performance of urlencode() and rawurlencode().
Improved unpack() performance with nameless repetitions by avoiding creating temporary strings and reparsing them.
Improved pack() performance.
Minor improvements in array_chunk() performance.
