簡素なログインプログラム(パスワード認証のCGI)の作成

Abstract

Web通信やサーバーの動きの理解の一助のため、
「ただログインするだけのWebページを作ってみるとよい」
という助言を受け、実行してみることにした。

ログイン画面のhtmlは簡単にできたが、
本丸のバックエンドプログラムの作成でてこづっている。

ここでは、
「パスワード認証をするだけの簡素なCGI」
を作ることを目標にして、同時進行で様子をレポートしていきたいと思う。

自己紹介

プログラミング経験数週間の初心者。簡単なスマホアプリを作ることを目標にしています。
仕事にするかはわからないが、とにかく知識や技術をつけて、生きる力にしたいと思っています。

要件定義

・パスワード認証機能（管理人が定めた固定パスワードによるもの）

設計

１．ログインページのhtml(login.html)のformタグのメソッド"POST"を使ってブラウザによって送られてきたパスワード入力情報を、サーバーのCGI(login.php)にて受け取る。

２．受け取ったパスワード入力が、管理人が定めたパスワード"mintia"と一致するかどうか確かめ、
　　　　一致する場合はブラウザにログイン先のページ(youkoso.html)を返して、
　　　　一致しない場合はブラウザに「パスワードが間違っています」と表示させる。

【WordPress】分割された記事（投稿）の最後のページかどうかを判定する

記事分割した時、カスタムフィールドで追加した項目を記事の一番最後にだけ表示させる

記事を分割した際に、最後のページだけコンテンツを表示させるために、
記事の最後のページかを判定する関数がWordPressの標準関数であるのかと思ったらなかった。
（is_paged()がそうかと思ったらアーカイブページとかで使う用でした）
なんでそれ用の関数を作ってみました。

ソース

テーマ以下のfunctions.phpに以下を追加
functions.php
// 投稿ページの分割ページの最後か
function is_post_page_end() {
    global $numpages;
    $paged = (get_query_var('page')) ? get_query_var('page') : 1;
    return $paged == $numpages;
}
使用例

分割された記事の最後のページだとtrueが返ります
single.php
<?php if ( is_post_page_end() ) : ?>
<p>この記事はこのページで最後です。</p>
<?php endif; ?>
おわり

もしかすると調べ切れてないだけで標準関数あったりするんですかね？

php-master-changes 2019-03-17

今日はビルドシステムのリファクタリングがあった！

2019-03-17

nunoplopes: check for bison binary, not yacc

https://github.com/php/php-src/commit/495a46aa1dc564656bf919cb49aae48a31ae15f4

[7.4~]

ビルドシステムで、AC_PROG_YACC を AC_CHECKPROG で bison をチェックする形に修正

Bison 3.3 で bison -y の挙動が厳格化されて posix yacc に沿わないコードを弾くようになったらしい

petk: [ci skip] Remove make install step from README

https://github.com/php/php-src/commit/86f2681460c7ebd28eefc82f32b879e1e26454c9

[7.4~]

README の「ソースからのビルド」の項から make install の部分を削除

他のとこに詳しく書くべきでないか、ということらしい

nunoplopes: snmp: remove unused var

https://github.com/php/php-src/commit/2619b138c0f3fe501f2b5b3924244237f02b7042

[7.4~]

昨日の修正の 7.4 へのバックポート

やった人が git 移行後の PHP のワークフロー（下位バージョンのブランチに当ててから上位バージョンへマージしていく）に慣れてない人だったのでこうなった

今だと開発版が 7.4 と 8.0 と両方あって、8.0 専用の修正以外には常に必要だしな

petk: Enhance the buildconf script

https://github.com/php/php-src/commit/78ab79b9164420679da7aba1f7195335d656afda

[7.4~]

ビルドシステムで、buildconf を改善

何をやるスクリプトなのかの説明を追加

-h、--help の追加

メッセージを修正して次に何やればいいか分かるように

他ディレクトリから実行できるよう、実行時にプロジェクトルートへ cd するよう修正

make があるかのチェック追加

petk の人、これ系の開発環境の地ならしでめっっっっっっっっちゃ色々頑張ってて、またコミットメッセージが丁寧でほぼ毎度元実装の背景調査して変更理由きっちり書いてて、開発への参入障壁下げ続けてるので、機能面は全然触ってない人だけど長い目で見て結構なヒーローだと思う

petk: Move distribution generator script to scripts/dev

https://github.com/php/php-src/commit/e525ce30a56767cb5bd71221dd98bdc09f3ee60f

[7.4~]

ビルドシステムで、makedist、genfiles をプロジェクトルートから scripts/dev へ移動

プロジェクトルートに入るもの限定した方がとりあえず何見ればいいか分かりやすく、リリース/パッケージ用スクリプトは普通の人そんなに使わないでしょ、ということらしい

実際現状でかなりスッキリしてて、5.6系のを比較用に見ると、おーという気持ちになる

あとドキュメント系を整理できればもっと減りそう

petk: Remove duplicate PHP_C_BIGENDIAN check

https://github.com/php/php-src/commit/20af19b9b3cbaf2821e56a4252c3b946e04b3190

[7.4~]

ext/hash で、config.m4 の不要な PHP_C_BIGENDIAN を削除

ビッグエンディアンチェックは configure.ac で済んでるから、ということらしい

nunoplopes: remove unneeded AC_REQUIRE([AC_PROG_YACC])

https://github.com/php/php-src/commit/33d428252699b679e420d414507fb0c5db4b3eac

[7.4~]

ビルドシステムで、不要な AC_REQUIRE([AC_PROG_YACC]) を削除

「これもいらないんじゃない？」とコミットへのコメントで petk の人が言ってた奴

【トラブルシューティング】xamppにおけるPHP7.3を使ってSymfonyをインストール

はじめに

今回のエラー

ProjectsというフォルダにSymfonyのインストローラーをインストールしようとしたところ…
C:\>cd Projects
C:\Projects>php -r "readfile('http://symfony.com/installer');" > symfony.phar
以下のようなエラーが出た。
PHP Warning:  failed loading cafile stream: `C:\xampp\apache\bin\curl-ca-bundle.crt' in Command line code on line 1
PHP Warning:  readfile(): Failed to enable crypto in Command line code on line 1
PHP Warning:  readfile(http://symfony.com/installer): failed to open stream: operation failed in Command line code on line 1
以下のサイト

⇒https://curl.haxx.se/docs/caextract.html
C:\Projects>php -r "readfile('http://symfony.com/installer');" > symfony.phar
C:\Projects>php symfony.phar
インストーラーをインストールできた。
```
Symfony Installer (1.5.11)
==========================

This is the official installer to start new projects based on the
Symfony full-stack framework.

To create a new project called blog in the current directory using
the latest stable version of Symfony, execute the following command:

symfony.phar new blog

Create a project based on the Symfony Long Term Support version (LTS):

symfony.phar new blog lts

Create a project based on a specific Symfony branch:

symfony.phar new blog 2.8 or symfony.phar new blog 3.0

Create a project based on a specific Symfony version:

symfony.phar new blog 2.8.1 or symfony.phar new blog 3.0.1

Create a demo application to learn how a Symfony application works:

symfony.phar demo

Updating the Symfony Installer

New versions of the Symfony Installer are released regularly. To update your
installer version, execute the following command:

symfony.phar self-update

C:\Projects>php symfony.phar new classic-symfony 3.4

【エラー解決法】xamppにおけるPHP7.3を使ってSymfony3.4をインストール

はじめに

ProjectsというフォルダにSymfonyのインストローラをダウンロードしようとしたところ・・・
C:\Projects>php -r "readfile('http://symfony.com/installer');" > symfony.phar
次のエラーが出た。
これは、『curl-ca-bundle.crt』という名のSSL証明書が見つからないという意味らしい。
PHP Warning:  failed loading cafile stream: `C:\xampp\apache\bin\curl-ca-bundle.crt' in Command line code on line 1
PHP Warning:  readfile(): Failed to enable crypto in Command line code on line 1
PHP Warning:  readfile(http://symfony.com/installer): failed to open stream: operation failed in Command line code on line 1
（１）SSL証明のダウンロード

赤枠をクリックし、SSL証明書をダウンロードする。
リンク：https://curl.haxx.se/docs/caextract.html

（２）SSL証明書を指定のフォルダに置く

cacert.pemをca-bundle-curl.crtというファイル名に変更。
『C:\xampp\apache\bin\』に置く。

（３）インストーラのダウンロード

再度、インストーラをダウンロードしてみると・・・
```
C:\Projects>php -r "readfile('http://symfony.com/installer');" > symfony.phar

//成功
```

（４）インストーラの実行

インストーラを実行してみると・・・
```
C:\Projects>php symfony.phar

Symfony Installer (1.5.11)
==========================

//成功
```

（５）プロジェクトフォルダの作成

Symfonyのプロジェクトフォルダを作成し、Symfonyのバージョンを指定
C:\Projects>php symfony.phar new classic-symfony 3.4
ここで次のエラーが出たが、これはPHP7.3を用いたアプリで表示されるらしい。
致命的なものではなく、警告らしい。

【エラー解決法】xamppのPHP7.3でSymfony3.4をインストールしたいけど、SSL-CA証明書が無い

はじめに

ProjectsというフォルダにSymfonyのインストローラをダウンロードしようとしたところ・・・
C:\Projects>php -r "readfile('http://symfony.com/installer');" > symfony.phar
次のエラーが出た。
これは、『curl-ca-bundle.crt』という名のSSL-CA証明書が見つからないという意味らしい。
『C:\xampp\apache\bin』を探してみても、『curl-ca-bundle.crt』というファイルが同梱されていない・・・
PHP Warning:  failed loading cafile stream: `C:\xampp\apache\bin\curl-ca-bundle.crt' in Command line code on line 1
PHP Warning:  readfile(): Failed to enable crypto in Command line code on line 1
PHP Warning:  readfile(http://symfony.com/installer): failed to open stream: operation failed in Command line code on line 1
SSL-CA証明書をcurl公式サイトからダウンロードし、フォルダに入れてみる。
リンク：https://curl.haxx.se/

（１）curl公式サイトからSSL-CA証明書をダウンロード

赤枠をクリックし、SSL-CA証明書をダウンロードする。
リンク：https://curl.haxx.se/docs/caextract.html

（２）SSL-CA証明書を指定のフォルダに置く

cacert.pemをca-bundle-curl.crtというファイル名に変更。
『C:\xampp\apache\bin\』に置く。

（３）インストーラのダウンロード

再度、インストーラをダウンロードしてみると・・・
C:\Projects>php -r "readfile('http://symfony.com/installer');" > symfony.phar

//成功
（４）インストーラの実行

インストーラを実行してみると・・・
C:\Projects>php symfony.phar

 Symfony Installer (1.5.11)
 ==========================

//成功
（５）プロジェクトフォルダの作成

Symfonyのプロジェクトフォルダを作成し、Symfonyのバージョンを指定
C:\Projects>php symfony.phar new classic-symfony 3.4
ここで次のエラーが出たが、これはPHP7.3を用いたアプリで表示されるらしい。
致命的なものではなく、警告らしい。

PHPからMySQLを利用する

1. はじめに

PHPからMySQLへ接続し，ブラウザ上にデータベースの内容を表示する．
例として，商品表を扱う．

前提条件

MAMPが起動済み（PHPとMySQLの利用が可能である）

データベースtestが作成済み

テーブルshouhinが作成済み

サーバはlocalhostとする

MySQLのユーザ名とパスワードはともにrootとする（mampのMySQLにおけるデフォルトのもの）

PHPでのエラーチェック

PHPでエラーが発生した際にブラウザ画面に表示する関数を記載しておく．
ただし，表示されないエラーもあるため注意すること．
<?php
    ini_set('display_errors',1);
?>
参考

PHPのエラー表示設定について

2. 内容

2.1. データ

テーブル shouhin には以下のデータが登録されている．
列numと列hinmeiはTEXT型，列kakakuはINTEGER型である．

num hinmei kakaku

010 pc 80000

011 display 35000

020 printer 25000

025 keyboard 1000

030 mouse 3000

2.2. ソースコード

2.2.1. 先頭1行目のデータを表示
showtable.php
<!DOCTYPE html>
<html lang="ja">
<head>
    <meta charset="utf-8">
    <title>商品表</title>
    <style></style>
</head>
<body>
    <?php
        //MySQLのデータベースサーバへ接続（サーバ名，接続ユーザ名，パスワード，データベース名 の順に指定）
        $link=mysqli_connect("localhost","root","root","test");

        //SQL文を指定
        $query="SELECT * FROM shouhin";

        //PHPからSQL文を実行（接続名 $link に対して $query のSQL文を実行）
        //結果は$resultに格納される
        $result=mysqli_query($link,$query);

        //$result から1行取り出して，1項目ごとに配列 $row (フィールド名をキーとした連想配列)に格納
        $row=mysqli_fetch_assoc($result);

        //$row 配列の中身を表示
        echo "番号：".$row['num']."<br>";
        echo "品名：".$row['hinmei']."<br>";
        echo "価格：".$row['kakaku']."<br>";
    ?>
</body>
</html>
2.2.2. 全データを表示
showtable.php
<!DOCTYPE html>
<html lang="ja">
<head>
    <meta charset="utf-8">
    <title>商品表</title>
    <style>
            table,th,td {
                border-collapse:collapse;
                border:1px solid black;
                line-height:1.5;
            }
        </style>
</head>
<body>
    <h1>商品表</h1>
    <?php
        $link=mysqli_connect("localhost","root","root","test");
        $query="SELECT * FROM shouhin";
        $result=mysqli_query($link,$query);

        echo "<table>";
        echo "<tr bgcolor=#87cefa>
                  <th>番号</th>
                  <th>品名</th>
                  <th>価格</th>
              </tr>";
        while($row=mysqli_fetch_assoc($result)){
            echo "<tr>
                      <td>{$row['num']}</td>
                      <td>{$row['hinmei']}</td>
                      <td>{$row['kakaku']}</td>
                  </tr>";
        }
        echo "</table>";
    ?>
</body>
</html>
※関数はmysql_･･･ではなくmysqli_･･･であることに注意
※本来はtry-catch文で例外（MySQLへ正常に接続できなかった場合）を考慮するが，分かりやすくするためにあえて例外を考慮しない
※区別しやすくするためにあえて字下げしている．タグごとにecho文で分けても良い．

全てを1つのecho文にまとめた例と分けた時の例を下に示す．どちらも同じ意味を持つ．
<?php
    echo "<div><p>あいうえお</p></div>";
?>
<?php
    echo "<div>";
    echo "<p>";
    echo "あいうえお";
    echo "</p>";
    echo "</div>";
?>
3. おわりに

さらに，

データ登録画面

データ削除画面

データ更新（編集）画面

hinmeiやkakakuの絞り込み検索機能（表示画面に追加）

などがあると便利ですね．気が向いたら記事を作成します．
プログラムは既に作成してあるんですけどね･･･．

num	hinmei	kakaku
010	pc	80000
011	display	35000
020	printer	25000
025	keyboard	1000
030	mouse	3000
