Extend no PHP
Essa encontrei na net, simples exemplo de como criar herança no PHP usando OOP. Daqui a pouco vou postar uma class que estou fazendo no trabalho para conexão ao MySQL.
abs
<?php
abstract class Mamifero
{
private $habitat;
private $no_patas;
protected function setHabitat ($habitat)
{
$this->habitat = $habitat;
}
protected function setNoPatas ($integer)
{
$this->no_patas = $integer;
}
}
?>
setHabitat ('terrestre');
$this->setNoPatas (2);
}
public function fala ($texto)
{
echo $texto;
}
}
?>
ABAP – Lendo dados de um arquivo
Olá, é bem fácil ler um arquivo utilizando o ABAP para preservar os dados no SAP. Abaixo um código de simples utilização
" Nome do Programa REPORT ZCHAP2604. * Um parameter para a importação do arquivo PARAMETERS FILENAME(128) DEFAULT 'c:\users\default\testfile.dat' LOWER CASE. " Tabela customers. TABLES CUSTOMERS. " Declaração da variavel all_customers " Do mesmo tipo da estrutura CUSTOMERS " Com linha de header para cabeçalho DATA: ALL_CUSTOMERS LIKE CUSTOMERS OCCURS 100 WITH HEADER LINE. " Função standard para upload CALL FUNCTION 'WS_UPLOAD' EXPORTING FILENAME = FILENAME TABLES DATA_TAB = ALL_CUSTOMERS EXCEPTIONS FILE_OPEN_ERROR = 1 OTHERS = 2. CASE SY-SUBRC. WHEN 1. WRITE 'Erro para abrir!'. EXIT. WHEN 2. WRITE 'Erro na transferência'. EXIT. ENDCASE. * O resultado da tabela interna no programa LOOP AT ALL_CUSTOMERS. WRITE: / ALL_CUSTOMERS-NAME, ALL_CUSTOMERS-CITY. ENDLOOP.

SQL – Limit em diferentes bases de dados
Todo mundo já usou o Limit para fazer uma paginação, por exemplo, vejamos como criar um limit nos três banco de dados mais “famosos”..rs
// mysql select col from tbl limit 20; // Oracle select col from tbl where rownum<=20; // Microsoft SQL select top 20 col from tbl; // Firebird select first 5 * from clientes // Primeiro 5 registros select last 5 * from clientes // Últimos 5 registros // DB2 da IBM // Os 5 primeiros somente select * from clientes fetch first 5 rows only // PostgresSQL SELECT * FROM tbl LIMIT 1 OFFSET 5
Acho que dá para ajudar em alguma coisa né...rs

iPad – Detectando iPad com diferentes plataformas
A Apple vendeu, somente nos EUA, 700 mil iPad no primeiro final de semana do lançamento oficial. Vejamos agora como identificar, em diferentes plataformas, o tablet da Apple.
Usando o bom e velho JavaScript:
var iPad = navigator.userAgent.match(/iPad/i) != NULL;
Usando o nosso amigo PHP
$VAR = strpos($_SERVER["HTTP_USER_AGENT"],"ipad"); // VERDADEIRO OU FALSO
Usando o bom e VELHO asp clássico 
request.servervariables("http_user_agent") == "iPad"
Em ASP.net tem mais ou menos uma maneira
Dim ServerVar, tmpValue As String
For Each ServerVar In Request.ServerVariables
tmpValue = Request.ServerVariables(ServerVar)
Response.Write(ServerVar & " = " & tmpValue & "")
Next
Para o .Net tem uma lista com os SERVERS_Variables…
