Recopilatorio 2008 de PHP Senior

El blog de php senior siempre me ha gustado por las conclusiones sacadas directamente de la experiencia de su autor 😀

Hace tiempo descubrí un pequeño índice/recopilatorio que sintetiza de alguna forma todo lo que nos falta a los desarrolladores PHP para poder empezar a considerarnos «Seniors».

Esto es lo que el autor ha aprendido con los años y ha intentado compartir, tratando de lograr conciencia de nuestras carencias y que no podemos quedarnos solo con aprender la sintaxis particular de un lenguaje. Tenemos que romper con el modelo clásico de «programador» («dominio del lenguaje») y pasar a «desarrollador» («dominio del sistema»).

Los artículos fundamentales hasta julio 2008

  1. Los desarrolladores debemos profesionalizarnos
  2. Buenas Prácticas de Desarrollo en PHP
  3. Code Smell – ¿A qué huele tu código?»
  4. Principios de Diseño Orientado a Objetos
  5. Programación Orientada a la Interface
  6. Herencia de clases y el «Principio de Liskov»
  7. Diseño en 3 capas
  8. Separar el código de la capa de presentación
  9. NO es necesaria la herencia múltiple
  10. NO es necesario crear un nuevo framework
  11. Capas de Abstracción
  12. Diferencias entre Lenguajes y Plataformas
  13. Estándares o muerte… para PHP
  14. Cómo traducir de UML a PHP5
  15. Los métodos «getter / setter»
  16. Standard PHP Library
  17. Patrones de Diseño
  18. Patrón Singleton en un entorno web con PHP
  19. Es fundamental contar con namespaces
  20. Migrar definitivamente a PHP5
  21. PHP Coding Standard (draft)
  22. Seven Steps to Better PHP code – part 1
  23. Seven Steps to Better PHP code – part 2

'parámetros opcionales'cuantos caracteres necesitas y la ubicación de la cadena de donde sacarlos
Private Function dame_text_rnd(optional cuantos As Integer=1, optional cadena as string=c_caracteres) As String
Dim i As Integer
Dim longitud as integer
longitud=Len(cadena)
Randomize   For i = 1 To cuantos
dame_text_rnd = dame_text_rnd && Mid(cadena, Int((longitud * Rnd) + 1), 1)
Next i
End Function
