<h1>Introdução</h1>
<p align="justify"><font face="Verdana">Programar é uma tarefa difícil. Difícil e trabalhosa. É uma arte, que exige experiência, dedicação, conhecimento, habilidade, criatividade, etc. O presente texto mostra, aos interessados, como preparar uma classe para manipular tabelas em bases de dados.</font></p>
<p align="justify"><font face="Verdana">Há três recomendações para tornar a difícil arte, menos traumática:</p>
<ol>
<li>Refinamentos sucessivos</li>
<li>Programação estruturada</li>
<li>Programação Orientada a Objetos</li>
</ol>
<p></font></p>
<p align="justify"><font face="Verdana">Além das recomendações acima, a disciplina e o conhecimento das técnicas associadas a linguagens específicas são fundamentais. E as ferramentas, finalmente. Para base de dados uso o MySQL Workench e o MySQL Administator. Para editar os programas em PHP, uso o PHPDezigner e o Enterprise Architect para modelar meus projetos de desenvolvimento, em UML (Unified Modeling Language). Uso UML, também, para modelagem de negócios e modelagem de topologias de redes, de longa distância ou complexas, sobre as quais aplica-se os protocolos BGP, OSPF, RIP e associados (MPLS, por exemplo). A UML é ótima para modelar, inclusive, os componentes dinâmicos envolvidos em tais protocolos. Falo sobre tais ferramentas não porque sejam as melhores. As melhores ferramentas são aquelas com as quais você projeta e desenvolve seu estilo, de forma gratificante.</font></p>
<p align="justify"><font face="Verdana">O principal objetivo deste trabalho é o desenvolvimento de programação orientada a objetos, em PHP. Usaremos o método direto, onde a didática tem valor significativo. Não é um texto para programadores muito experientes. É um texto para os iniciantes ou aqueles experientes interessados no aperfeiçoamento pessoal.</font></p>
<h1>Construção da classe</h1>
<p align="justify"><font face="Verdana">Inicio as classes, usualmente, com três componentes: a propriedade (variável) que irá identificar o número de instâncias abertas, e os métodos construtor e destrutor. O método construtor conta as instâncias. E, um pequeno programa serve para testar cada etapa do processo de refinamento sucessivo. Eis a primeira versão, abaixo:</font></p>
<pre>
&lt;?php
// Versão 1
class BancodeDados extends mysqli {

    static $idBancodeDados = 0;

    /**
     * Construtor:
     *
     * 1. Conta o número de instâncias.
    */

    public function __construct() {
        self::$idBancodeDados++;
    }

    public function __destruct() {
        --self::$idBancodeDados;
    }
}
</pre>
<p align="justify"><font face="Verdana">Eis o teste e respectivo resultado:</font></p>
<pre>
&lt;?php
// Versão 1
require_once (&#039;../includes/funcoesgerais.phpm&#039;);
require_once (&#039;../includes/db.phpm&#039;);

$db_faleok = new db();
echo &quot;Instâncias abertas: " . BancodeDados::$idBancodeDados;

$db_faleok1 = new db();
echo "Instâncias abertas: " . BancodeDados::$idBancodeDados;

?&gt;

Instâncias abertas: 1
Instâncias abertas: 2
</pre>
<p align="justify"><font face="Verdana">O interessante a observar acima são os seguintes pontos:</p>
<ul>
<li>A propriedade estática <strong>$idBancodeDados</strong> é incrementada no método <strong>__construtor</strong>, que como sabemos é executado na criação de uma instância da classe <strong>BancodeDados</strong>.</li>
<li>Uma propriedade estática é referenciada externamente como <strong>NomedaClasse::$NomedaPropriedade</strong>, pois ela pertence à <strong>própria</strong> classe.</li>
<li>A classe <strong>BancodeDados</strong>, herda métodos e funções da classe <strong>msqli</strong>, do PHP, uma vez que estamos usando <strong>extends mysqli</strong>, na sua declaração.</li>
<li>É bom lembrar, que o método <strong>__constructor</strong> não pode retornar valores. Esta noção será muito útil mais à frente. Entretanto pode-se observar que o exemplo acima ele altera o valor de uma propriedade estática, isto é, <strong>$idBancodeDados</strong>, que é como se fosse uma variável global.</li>
<li>O trecho:
<pre>
/**
 * Construtor:
 *
 * 1. Conta o número de instâncias.
*/
</pre>
<p>
é a documentação da classe. Como uso o <strong>phpdoc</strong> esta tarefa torna-se, em particular, muito importante.</li>
</ul>
<p></font></p>
<p align="justify"><font face="Verdana">Não se pode esquecer do registro de atividades. Foi construída uma classe chamada <strong>Mensagens</strong> que possui dois métodos. Um método exibe uma mensagem na tela, como acima, e o outro, grava a mensagem em um arquivo de &#8220;log&#8221;. Embora a classe <strong>Mensagens</strong> não seja exibida aqui (assim como outras que não a classe <strong>BancodeDados</strong>), o contexto a deixa claro. Eis como fica a versão 2 e seu resultado:</p>
<pre>
&lt;?php
$db_faleok1 = new BancodeDados();
Mensagem = "Instâncias abertas: " . BancodeDados::$idBancodeDados;
$msg-&gt;Exibe();
$msg-&gt;LogFaleOK();

$db_faleok2 = new BancodeDados();
$msg-&gt;Mensagem = "Instâncias abertas: " . BancodeDados::$idBancodeDados;
$msg-&gt;Exibe();
$msg-&gt;LogFaleOK();

?&gt;

20120121 11:55:43 - Instâncias abertas: 1
20120121 11:55:43 - Instâncias abertas: 2
</pre>
<p></font></p>
<p align="justify"><font face="Verdana">As observações sobre a Versão 2 do teste são:</p>
<ul>
<li>Aperfeiçoamos o nome das instâncias da classe <strong>BancodeDados</strong>, dando mais consistência visual (<strong>$db_faleok1</strong> e <strong>$db_faleok2</strong>). </li>
<li>A mensagem é exibida com a data. Fica mais claro o exemplo, além do fato de que elas estão sendo registradas no &#8220;log&#8221;, para eventuais acessos futuros.</li>
</ul>
<p></font></p>
<p align="justify"><font face="Verdana">Melhor ficaria, se a saída fosse aperfeiçoada, como a versão 3 do teste:</p>
<pre>
&lt;?php
Mensagem = "Teste da classe <strong>db</strong>, Versão 3";
$msg-&gt;Exibe();

$db_faleok1 = new BancodeDados();
$msg-&gt;Mensagem = "Instâncias abertas: " . BancodeDados::$idBancodeDados;
$msg-&gt;Exibe();
$msg-&gt;LogFaleOK();

$db_faleok2 = new BancodeDados();
$msg-&gt;Mensagem = "Instâncias abertas: " . BancodeDados::$idBancodeDados;
$msg-&gt;Exibe();
$msg-&gt;LogFaleOK();

?&gt;

20120121 12:09:30 - Teste da classe db, Versão 3
20120121 12:09:30 - Instâncias abertas: 1
20120121 12:09:30 - Instâncias abertas: 2
</pre>
<p></font></p>
<p align="justify"><font face="Verdana">O método direto exige algumas anotações sobre a Versão 3 do teste:</p>
<ul>
<li>Retiramos o comentário <strong>// Teste x</strong> do início e deixamos somente na mensagem a ser exibida na tela. Evitamos duas alterações de versões.</li>
<li>A mensagem da versão só é exibida na tela. Não é registrada no &#8220;log&#8221;.</li>
<li>Já percebe-se que o método construtor executa, imediatamente, ao se definir uma instância da classe. Mas, não temos noção do momento no qual o método destrutor é executado. Geralmente é depois que o programa principal termina (no nosso caso, o testegeral.php), ou logo depois da execução de algumas instruções após a última instrução que atua sobre a instância de uma classe.
</li>
</ul>
<p></font></p>
<p align="justify"><font face="Verdana">A fim de fixar bem a questão do destrutor, abaixo está a versão 2, da classe, na qual adicionamos comentários e alteramos o método <strong>__destruct</strong> incluindo dois comandos. O primeiro, subtraindo 1 da propriedade estática <strong>$idInstanciaDB</strong>, pois ela representa o número de instâncias. Destruir significa, também, não possuir nenhuma instância! Incluímos uma saída na tela, para imprimir o momento da destruição e somente mostramos os trechos importantes:</p>
<pre>
&lt;?php

      .
      .
      .
class db extends mysqli {

    static $idBancodeDados = 0;
      .
      .
      .
    public function __construct() {
        self::$idBancodeDados++;
    }

    public function __destruct() {
        --self::$idBancodeDados;
        echo 'Executou a destrutora as ' . date("Ymd H:i:s");
    }
}

Mensagem = "Teste da classe <strong>db</strong>, Versão 4";
$msg-&gt;Exibe();

$db_faleok1 = new BancodeDados();
$msg-&gt;Mensagem = "Instâncias abertas: " . BancodeDados::$idBancodeDados;
$msg-&gt;Exibe();
$msg-&gt;LogFaleOK();

$db_faleok2 = new BancodeDados();
$msg-&gt;Mensagem = "Instâncias abertas: " . BancodeDados::$idBancodeDados;
$msg-&gt;Exibe();
$msg-&gt;LogFaleOK();

?&gt;

20120121 17:19:01 - Teste da classe db, Versão 4
20120121 17:19:01 - Instâncias abertas: 1
20120121 17:19:01 - Instâncias abertas: 2
Executou a destrutora as 20120121 17:19:01
Executou a destrutora as 20120121 17:19:01
</pre>
<p></font></p>
<p align="justify"><font face="Verdana">Os comentários sobre o código acima:</p>
<ul>
<li>Duas instâncias foram abertas, portanto, duas execuções de destrutores.</li>
<li>Os métodos  destrutores foram executados em algum momento após o término do programa.</li>
</ul>
<p></font></p>
<p align="justify"><font face="Verdana">A versão final, completa e bem ilustrativa seria:</p>

20120122 14:20:25 - Teste da classe db, Versão 4

</pre>
<p></font></p>
<p align="justify"><font face="Verdana">Eis as observações sobre o código acima:</p>
<ul>
<li>A forma de executar o destrutor, para uma determinada instância da classe é: <strong>$nome_da_Instância-&gt;NULL;</strong>.</li>
<li>Executar ou não o destrutor é uma decisão do programador. Se o programador gosta de exercer o controle total sobre seu código, então ele destrói.</li>
</ul>
