For the most part the developers of the PHP language have tried to be backwards compatible, so a script written for an older version should run (ideally) without changes in a newer version of PHP, in practice some changes will usually be needed.	現在、PHPは有名なスクリプト言語まで成長しており、各自のスクリプトで再利用可能な多くのコードとして公開されているリソースが存在します。PHP言語の開発者の大部分は、過去のバージョンとの互換製を保とうとしており、過去のバージョン用に書かれたスクリプトは(理想的には)より新しいバージョンのPHPで変更せずに動作するはずです。しかし、実際には、通常、いくつかの変更が必要となります。

In order to do that we check the user agent string that the browser sends as part of its HTTP request.	次により実用的なことをしてみましょう。ページを見ているユーザが使用しているブラウザの種類を確認してみます。これを行なうには、ブラウザが HTTPリクエストの一部として送信したuser agent文字列を調べます。この情報は、変数に保存されています。PHPでは、変数名は常にドル記号で始まります。今、使用する変数は、 $_SERVER["HTTP_USER_AGENT"] です。
The variable we are interested in right now is $_SERVER[ "HTTP_USER_AGENT"].	PHPのオートグローバルに関する注意 $_SERVER は、 Webサーバ関連情報を全て保持するPHPの特別な予約変数です。詳細は、オートグローバル (スーパーグローバルとも呼ばれます) を参照して下さい。これらの特別な変数は、PHP 4.1.0で導入されました。これ以前は、 $HTTP_SERVER_VARS のような古い配列 $HTTP_*_VARS を代わりに使用していました。古いとはいえ、これらの変数はまだ存在しています。 (古いコードに関する注記も参照して下さい。)

テキストエディタに関する注意 PHPファイルを作成、編集、監理する際に使用できる、多くのテキストエディタのや統合開発環境(IDE)があります。これらのツールのリストの一部は、 PHP エディタのリストで監理されています。あるエディタを推薦したい場合、上記のページを訪れ、ページの監理者にそのエディタをリストに加えてくれないかとたずねてみてください。

A partial list of these tools is maintained at PHP Editor 's List.

ワードプロセッサに関する注意 StarOffice Writer, Microsoft Word およびAbiwordのようなワードプロセッサは、PHPファイルの編集には不適です。

If you wish to use one for this test script, you must ensure that you save the file as PLAIN TEXT or PHP will not be able to read and execute the script.

このテストスクリプトの１つを使用したい場合、プレーンテキストとしてファイルを保存していることを確認して下さい。さもないと、PHP は、スクリプトを読み込んで実行できません。

You can then enter your filename without quotes.

ファイルを保存する際に、ファイル名を入力するプロンプトでファイル名を引用符で括ります。(すなわち、"hello.php"とします。)

Make a call to the phpinfo() function and you'll see a lot of useful information about your system and setup such as available Predefined Variables, loaded PHP modules, and configuration settings.

もしくは、保存ダイアログボックスにおいてドロップダウンメニュー"テキスト文書"をクリックし、"すべてのファイル"に設定を変更します。これにより、引用符を付けずにファイル名を入力することができます。

Please read the manual section on Variables from outside of PHP for more information and examples on using forms with PHP.

PHPの最も強力な機能の一つは、HTMLフォームを処理する手段です。理解するべき重要な基本概念は、あるフォームの中の全てのフォーム要素は、自動的にPHPスクリプトで利用可能になるということです。詳細は、マニュアルのセクション PHPの外部からくる変数およびPHPでフォームを使用する例を参照してください。以下にHTMLフォームの例を示します。

Example 2-6.

例 2-6簡単なHTMLフォーム

There is nothing special about this form.

このフォームに関して特別なところはありません。これは通常のHTML フォームで特殊なタグは全く使用していません。ユーザがこのフォームを記入し、投稿ボタンを押した時、 action.php ページがコールされます。このファイルには、以下のようなコードを記述します。

When the user fills in this form and hits the submit button, the action.php page is called.

例 2-7フォームからのデータを出力する

Earlier we used the $_SERVER autoglobal, now above we just introduced the $_POST Earlier we used the $_SERVER autoglobal, now above we just introduced the $_POST autoglobal which contains all POST data.

このスクリプトの出力例は次のようになります。

In this tutorial we assume that your server has support for PHP activated and that all files ending in .php are handled by PHP.

ここで、PHPの基礎の基礎について簡単なチュートリアルで説明したいと思います。ここでは、PHPはWebページを作成する機能だけを有しているわけではありませんが、PHPで動的なWebページを作成することのみを扱います。詳細は、 PHPでできることと題するセクションを参照して下さい。

Think of these PHP-enabled files as simple HTML files with a whole new family of magical tags that let you do all sorts of things.

PHPを使用できるWebページは、通常のHTMLページと全く同様に扱われ、通常のHTMLページを作成するのと同様の方法で編集することができます。

For the most part the developers of the PHP language have tried to be backwards compatible, so a script written for an older version should run (ideally) without changes in a newer version of PHP, in practice some changes will usually be needed.

現在、PHPは有名なスクリプト言語まで成長しており、各自のスクリプトで再利用可能な多くのコードとして公開されているリソースが存在します。PHP言語の開発者の大部分は、過去のバージョンとの互換製を保とうとしており、過去のバージョン用に書かれたスクリプトは(理想的には)より新しいバージョンのPHPで変更せずに動作するはずです。しかし、実際には、通常、いくつかの変更が必要となります。

The deprecation of the old $HTTP_*_VARS arrays (which need to be indicated as global when used inside a function or method).

古いコードに影響を与える最近の重要な二つの変更点を以下に示します。

The preferred method of accessing these values is via the autoglobal arrays mentioned above.

$HTTP_*_VARS 配列が過去のものとなったこと。 (これは、関数またはメソッドの中で使用する際にグローバル変数として宣言を行なう必要がありました。) 以下のオートグローバル配列がPHP 4.1.0で導入されました。これらを以下に示します。 $_GET, $_POST, $_COOKIE, $_SERVER, $_ENV, $_REQUEST, $_SESSION. 従来の$HTTP_POST_VARSのような配列 $HTTP_*_VARS もまだ存在し、PHP 3以来維持されています。

In order to do that we check the user agent string that the browser sends as part of its HTTP request.

次により実用的なことをしてみましょう。ページを見ているユーザが使用しているブラウザの種類を確認してみます。これを行なうには、ブラウザが HTTPリクエストの一部として送信したuser agent文字列を調べます。この情報は、変数に保存されています。PHPでは、変数名は常にドル記号で始まります。今、使用する変数は、 $_SERVER["HTTP_USER_AGENT"] です。

The variable we are interested in right now is $_SERVER[ "HTTP_USER_AGENT"].

PHPのオートグローバルに関する注意 $_SERVER は、 Webサーバ関連情報を全て保持するPHPの特別な予約変数です。詳細は、オートグローバル (スーパーグローバルとも呼ばれます) を参照して下さい。これらの特別な変数は、PHP 4.1.0で導入されました。これ以前は、 $HTTP_SERVER_VARS のような古い配列 $HTTP_*_VARS を代わりに使用していました。古いとはいえ、これらの変数はまだ存在しています。 (古いコードに関する注記も参照して下さい。)

See the related manual page on Autoglobals for more information.

この変数を表示するには、以下のようにします。

Before this time, we used the older $HTTP_*_VARS arrays instead, such as $HTTP_SERVER_VARS.

例 2-2変数を出力する (配列要素)

To display this variable, we can simply do:

このスクリプトの出力例は以下のようになります。

In the above example we printed an Array In the above example we printed an Array element.

PHPで利用可能な変数の型には多くの種類があります。上の例では、配列の要素を出力しています。配列は、非常に有用です。

A list can be seen in the Reserved Variables section of the manual or you can get a complete list of them by creating a file that looks like this:

$_SERVER は、自動的にPHPで利用可能な変数の一つに過ぎません。マニュアルの予約変数のセクションでリストを参照することができます。また、以下のようなファイルを作成することにより、完全なリストを入手することができます。
