1. $_SERVER['HTTP_USER_AGENT'] を通じてブラウザの種類を決定する PHP メソッドを作成しましょう。
$_SERVER['HTTP_USER_AGENT'] は主にここで使用され、ページを閲覧している訪問者が使用しているオペレーティング システムを確認します。ブラウザ (バージョン番号を含む) とユーザーの個人設定。使い方は非常に簡単で、プログラムから印刷するだけで理解できます。
2. さらに、PHP は、PHP システム関数 get_browser() 関数を通じてブラウザの種類を決定することもできます。この関数は、ユーザーのブラウザのパフォーマンス データを返します。
この関数は、ユーザーの browscap.ini ファイルを参照して、ユーザーのブラウザのパフォーマンスを測定します。成功した場合、関数はユーザーのブラウザ情報を含むオブジェクトまたは配列を返し、失敗した場合は false を返します。 get_browser 構文 get_browser(user_agent, return_array) この関数には 2 つのパラメータがあります。パラメータの意味は次のように説明されます。 user_agent はオプションです。 HTTP ユーザー エージェントの名前を指定します。デフォルトは $HTTP_USER_AGENT の値です。 NULL を設定すると、このパラメータをバイパスできます。
return_array オプション。このパラメータが true に設定されている場合、この関数はオブジェクトの代わりに配列を返します。 PHP が $_SERVER['HTTP_USER_AGENT'] および get_browser を通じて取得するブラウザー情報については、次の例で理解できます。
[browser_name_regex] => ^mozilla/. .0
警告: get_browser() [function.get-browser]: browscap ini ディレクティブが設定されていません...
By php マニュアルを参照すると、次のように説明されています。 この関数を使用するには、php.ini ファイル内の browscap.ini ファイルに構成ポイントを追加する必要があります。browscap.ini ファイルには、既存のすべてのブラウザの種類と情報が記録されます。最新のファイルをダウンロードし、browscap.ini をサーバー上のどこかに配置する必要があります。 get_browser() を使用すると、取得したクライアント情報がこのファイルと比較され、見つかった場合は対応するタイプが返されます。上記のことから、ブラウザの種類を取得するために get_browser() を使用するのはコストが高いようです。
3. PHP でブラウザの種類を判断する別の方法は、外国の専門家によって書かれたオープン ソース コードを使用することです。海外には mavrick というブラウザ プロジェクトがあり、作成した Browser クラスは更新され続けており、私が見た最新のクラスは iPhone、BlackBerry、win、mac、linux、OS、BeOS などのプラットフォームで入手できます。ブラウザ情報機能は非常に強力だと言えます。
さて、PHP でブラウザの種類を判断する方法をまとめました。方法は 3 つありますが、要求される精度がそれほど高くない場合は、最初の方法で十分です。 2 番目の方法と 3 番目の方法は、信頼性が判断されていないにもかかわらず、少し詳細すぎるため、複雑であることは明らかです。
