まず PHP の基礎を学び、次に Baidu にアクセスして必要な機能の原理を確認し、実験が成功したら Web サイトで使用してください。
これらの 4 つのステップを完了すると、このテクノロジーの機能を学習したことになります。
PHP を学べない人のほとんどは、最初のステップを繰り返しています。
w3school のチュートリアルは非常に基本的でわかりやすいので、最初に読むことをお勧めします。次に、php100のビデオチュートリアルをご覧ください。このビデオチュートリアルは非常に詳細でわかりやすく、私もこれを見て勉強しました。
前にも言いましたが、チュートリアルを見ているだけでは、掛け算の公式を暗記しているだけです。掛け算の公式しか知らない生徒は、それを使って初めて本当の学習ができるのです。
最も単純なプログラムは次のとおりです:
echo 'Hello, world!';
?>
ダウンロード PHP は www.php.net でダウンロードでき、Windows でバイナリ コードを選択すると、ダウンロードできます。インストール パッケージと ZIP パッケージ。私は ZIP パッケージが好きです。c:\php\ などのフォルダーに解凍するだけです。上記で保存した PHP ファイル (メモ帳で編集しました) をダブルクリックし、ロックを解除した c:\php\php.exe へのリンクを選択します。
