PHP 8.5 is a major update of the PHP language. It contains many new features, such as the new URI extension, support for modifying properties while cloning, the Pipe operator, performance improvements, bug fixes, and general cleanup.
PHP 8.5 is here, faster, cleaner, and built for developers.
PHP 8.5 introduces the |> operator to chain callables left-to-right, passing values smoothly through multiple functions natively.
Retrieve the first or last value of any array effortlessly, without changing internal pointers or writing extra helper code.
Clone objects and update properties with the new clone() syntax, making the "with-er" pattern simple for readonly classes.
PHP 8.5 adds a built-in URI extension to parse, normalize, and handle URLs following RFC 3986 and WHATWG standards.
The #[\NoDiscard] attribute warns when a return value isn’t used, helping prevent mistakes and improving overall API safety.
New CurlSharePersistentHandle class, curl_multi_get_handles(), curl_share_init_persistent() functions.
PHP 8.5 adds a new operator, the pipe operator |> to chain multiple callables from left to right, taking the return value of the left callable and passing it to the right.
$input = ' Some kind of string. ';
$output = strtolower(
str_replace(['.', '/', '…'], '',
str_replace(' ', '-',
trim($input)
)
)
);
var_dump($output);
// string(19) "some-kind-of-string"$input = ' Some kind of string. ';
$output = $input
|> trim(...)
|> (fn($str) => str_replace(' ', '-', $str))
|> (fn($str) => str_replace(['.', '/', '…'], '', $str))
|> strtolower(...);
var_dump($output);
// string(19) "some-kind-of-string"PHP 8.5 adds two new functions for retrieving the first and last values of an array. These functions complement the array_key_first and array_key_last functions.
$php = [
'php-82' => ['state' => 'security', 'branch' => 'PHP-8.2'],
'php-83' => ['state' => 'active', 'branch' => 'PHP-8.3'],
'php-84' => ['state' => 'active', 'branch' => 'PHP-8.4'],
'php-85' => ['state' => 'upcoming', 'branch' => 'PHP-8.5'],
];
$upcomingRelease = null;
foreach ($php as $key => $version) {
if ($version['state'] === 'upcoming') {
$upcomingRelease = $version;
break;
}
}
var_dump($upcomingRelease);$php = [
'php-82' => ['state' => 'security', 'branch' => 'PHP-8.2'],
'php-83' => ['state' => 'active', 'branch' => 'PHP-8.3'],
'php-84' => ['state' => 'active', 'branch' => 'PHP-8.4'],
'php-85' => ['state' => 'upcoming', 'branch' => 'PHP-8.5'],
];
$upcomingRelease = array_first(
array_filter(
$php,
static fn($version) => $version['state'] === 'upcoming'
)
);
var_dump($upcomingRelease);It is now possible to update properties during object cloning by passing an associative array with the updated to the clone() function. This enables straight-forward support of the "with-er" pattern for readonly classes.
