Queria um sistema extremamente simples para trocar mensagens entre dois computadores na rede, como é uma rede corporativa com vários bloqueios não seria possível usar algum Instant Messenger e também eu não queria ter de instalar um cliente (programa) somente para isto.
Pesquisando na web achei algumas soluções em PHP, juntando algumas idéias consegui atender minha necessidade.
O “banco de dados” fica armazenado num arquivo HTML dentro da própria pasta web onde o sistema é hospedado.
Na linha 6 do index.php configure seu nome como Admin (somente para o admin aparece um link para limpar a conversa)
Basta armazenar os três arquivos numa pasta do seu servidor web.
index.php
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<?
date_default_timezone_set('America/Sao_Paulo');
$ADMIN = "Daniel";
?>
