Raxos

Appearance

UserAgent ​

Raxos\Http\UserAgent

Parses a User-Agent header string into a browser, platform and version. It is immutable and implements JsonSerializable and Stringable.

php
readonly class UserAgent implements JsonSerializable, Stringable

Constructor ​

php
public function __construct(protected string $userAgent)

Parses the given user agent string. The parsed pieces are available as the public readonly properties browser, platform and version, each of which may be null when it could not be determined.

HttpRequest::userAgent() builds this object for you from the request header, so you rarely construct it by hand.

Methods ​

php
public function isChrome(): bool

Returns true when the browser is Google Chrome.

php
public function isFirefox(): bool

Returns true when the browser is Mozilla Firefox.

php
public function isSafari(): bool

Returns true when the browser is Apple Safari.

php
public function isInternetExplorer(): bool

Returns true when the browser is Microsoft Internet Explorer.

php
public function isMicrosoftEdge(): bool

Returns true when the browser is Microsoft Edge.

php
public function versionAtLeast(string $version): bool

Returns true when the parsed browser version is at least the given version.

Example ​

php
<?php
declare(strict_types=1);

use Raxos\Http\HttpRequest;

$request = HttpRequest::createFromGlobals();
$agent = $request->userAgent();

if ($agent !== null && $agent->isChrome() && $agent->versionAtLeast('120')) {
    // serve the modern bundle
}
