About the Book
La accesibilidad de PHP puede ser una trampa. Por un lado, es muy fácil llegar a crear una aplicación bastante potente a poco que tengas algunas nociones de programación y busques un poco de ayuda en Internet.
Pero es igualmente fácil que tus programas crezcan caóticamente, duplicando código por todas partes, mezclando bibliotecas, ideas fallidas y fuentes de errores por todas las esquinas, reinventando la rueda a cada paso y siendo incapaz de lograr un montón de cosas.
Este libro es el resultado de haber pasado por ese proceso y haber llegado, más o menos, a escribir un código cada vez mejor e inteligible y, sobre todo, un código más sólido y fácil de mantener en el largo plazo. Si te has convertido en desarrollador por las circunstancias de tu trabajo y quieres llegar a un nivel de profesionalidad aceptable, este libro puede serte de gran ayuda.
