			<content:encoded><![CDATA[<p>var_dump — Mostra informações sobre a variável</p>
<p>Esta função imprime uma saída de algumas informações sobre a variável que você passou. Será realmente aceito qualquer número de variáveis para que você possa usar uma chamada pela função para obter informação sobre muitas variáveis.</p>
<p>É uma boa idéia para a saída do tag HTML antes de chamar a função. Isto irá exibir o espaço branco em um formato amigável mais humana. Com a extensão Xdebug instalada, a saída será formatado e cor codificadas para facilitar a legibilidade.</p>

			<content:encoded><![CDATA[<p>Atendendo a pedidos do amigo Micox.</p>
<blockquote><p><strong>A diferença entre Internet e World Wide Web</strong></p>
<p>“Muita gente usa os termos Internet e World Wide Web (ou apenas Web) indistintamente, mas de fato os dois termos não são sinônimos. A Internet e a Web são duas coisas separadas, embora relacionadas.</p>
<p>A internet é uma gigantesca rede de redes, uma infraestrutura em rede. Ela conecta milhões de computadores globalmente, formando uma rede em que qualquer computador pode comunicar-se com qualquer outro computador deste que ambos estejam conectados à Internet. A informação que viaja pela Internet o faz por meio de uma variedade de linguagens conhecidas por protocolos.</p>
<p>A World Wide Web, ou simplesmente Web, é uma maneira de acessar informação por meio da Internet. É um modelo de compartilhamento de informações construído sobre a Internet. A Web usa o protocolo HTTP, que é apenas uma das linguagens utilizadas na Internet, para transmitir informações, e serve-se de browsers, como o Internet Explorer, para acessar documentos chamados páginas (home pages), que estão ligados uns a outros por meio de hyperlinks. Documentos Web também contém gráficos, sons, textos e vídeos.</p>
<p>A Web é apenas uma das maneiras pelas quais a informação pode ser disseminada pela Internet. A Internet, não a Web, é utilizada ainda para e-mail, Newsgroups, Instant Messaging e FTP. Portanto a Web é apenas uma parte da Internet, embora uma grande parte, mas os dois termos não são sinônimos e não devem ser confundidos.”</p></blockquote>
