New Features
PHP Core
Integer Octal Literal Prefix
Octal integers can now use an explicit
0o/0O
prefix in integer literals,
similarly to binary and hexadecimal integer literals.
<?php
014; // Non-prefix octal literal
0o14; // Prefixed octal literal
?>
Array Unpacking with String Keys
Added support for array unpacking with strings keys.
<?php
$arr1 = [1, 'a' => 'b'];
$arr2 = [...$arr1, 'c' => 'd']; //[1, 'a' => 'b', 'c' => 'd']
?>
Named Argument After Argument Unpacking
It is now possible to specify named arguments after an argument unpack. e.g. foo(...$args, named: $arg).
full-path Key for File Uploads
File uploads now provide an additional full_path key,
which contains the full path (rather than just the basename) of the uploaded file.
This is intended for use in conjunction with "upload webkitdirectory".
Enumerations
Support for Enumerations has been added.
Fibers
Support for Fibers has been added.
First Class Callable Syntax
Closures for callables can now be created using the syntax myFunc(...),
which is identical to Closure::fromCallable('myFunc').
Note: The
...is part of the syntax, and not an omission.
Intersection Types
Support for intersection types has been added.
Intersection types cannot be used together with union types
Never type
A new return only type never has been added. This indicates that a function either exit(), throws an exception, or doesn't terminate.
new in Initializers
It is now possible to use new ClassName() expressions as the
default value of a parameter, static variable, global constant initializers,
and as attribute arguments.
Objects can also be passed to define() now.
Readonly properties
Support for readonly has been added.
Final class constants
Added support for the final modifier for class constants. Also, interface constants become overridable by default.
CURL
Added the CURLOPT_DOH_URL option.
Added options for blob certificate when libcurl >= 7.71.0:
-
CURLOPT_ISSUERCERT_BLOB -
CURLOPT_PROXY_ISSUERCERT -
CURLOPT_PROXY_ISSUERCERT_BLOB -
CURLOPT_PROXY_SSLCERT_BLOB -
CURLOPT_PROXY_SSLKEY_BLOB -
CURLOPT_SSLCERT_BLOB -
CURLOPT_SSLKEY_BLOB
Added CURLStringFile, which can be used to post a file from a string rather than a file:
<?php
$file = new CURLStringFile($data, 'filename.txt', 'text/plain');
curl_setopt($curl, CURLOPT_POSTFIELDS, ['file' => $file]);
?>
FPM
Added openmetrics status format. It can be used by Prometheus to fetch FPM metrics.
Added new pool option for the dynamic process manager called
pm.max_spawn_rate. It allows to start a number of children
at a faster rate when dynamic pm is selected.
The default value is 32 which was the previous
hard coded value.
GD
Avif support is now available through imagecreatefromavif() and imageavif(), if libgd has been built with Avif support.
Hash
The following functions hash(),
hash_file(), and hash_init()
now support an additional optional options
argument, which can be used to pass algorithm specific data.
MurmurHash3
Added support for MurmurHash3 with streaming
support. The following variants are implemented:
- murmur3a, 32-bit hash
- murmur3c, 128-bit hash for x86
- murmur3f, 128-bit hash for x64
The initial hash state can be passed through the seed
key in the options array, for example:
<?php
$h = hash("murmur3f", $data, options: ["seed" => 42]);
echo $h, "\n";
?>
0
to the platform defined UINT_MAX, usually
4294967295.
xxHash
Added support for xxHash.
The following variants are implemented:
- xxh32, 32-bit hash
- xxh64, 64-bit hash
- xxh3, 64-bit hash
- xxh128, 128-bit hash
The initial hash state can be passed through the seed
key in the options array, for example:
<?php
$h = hash("xxh3", $data, options: ["seed" => 42]);
echo $h, "\n";
?>
secret
key in the options array, too:
<?php
$h = hash("xxh3", $data, options: ["secret" => "at least 136 bytes long secret here"]);
echo $h, "\n";
?>
MySQLi
New INI directive mysqli.local_infile_directory
The mysqli.local_infile_directory INI directive has been added, which can be used to specify a directory from which files are allowed to be loaded. It is only meaningful if mysqli.allow_local_infile is not enabled, as all directories are allowed in that case.
Binding parameters in execute
It is now possible to bind parameters by passing them as an array to mysqli_stmt::execute(). All values will be bound as strings. Only list arrays are allowed. This new feature is not available when MySQLi is compiled with libmysqlclient.
<?php
$stmt = $mysqli->prepare('INSERT INTO users(id, name) VALUES(?,?)');
$stmt->execute([1, $username]);
?>
New method mysqli_result::fetch_column()
mysqli_result::fetch_column()
has been added to allow fetching a single scalar value from the result set.
The new method accepts an optional 0-based column
parameter of type int specifying which column to fetch from.
<?php
$result = $mysqli->query('SELECT username FROM users WHERE id = 123');
echo $result->fetch_column();
?>
PDO
The PDO::MYSQL_ATTR_LOCAL_INFILE_DIRECTORY attribute
has been added, which can be used to specify a directory from which files
are allowed to be loaded.
It is only meaningful if PDO::MYSQL_ATTR_LOCAL_INFILE
is not enabled, as all directories are allowed in that case.
PDO_SQLite
SQLite's "file:" DSN syntax is now supported,
which allows specifying additional flags.
This feature is not available if open_basedir is set.
<?php
new PDO('sqlite:file:path/to/sqlite.db?mode=ro')
?>
POSIX
Added POSIX_RLIMIT_KQUEUES and POSIX_RLIMIT_NPTS.
These rlimits are only available on FreeBSD.
Standard
fputcsv() now accepts a new
eol argument which allows to define a custom
End of Line sequence, the default remains the same and is "\n".
SPL
SplFileObject::fputcsv() now accepts a new
eol argument which allows to define a custom
End of Line sequence, the default remains the same and is "\n".
