Entre las comillas dobles hay tres modos de usar variables:
echo "$variable_simple";echo "$un_array[id]"; // array unidimencional. sin comillas dentroecho "{$un_array['user']['id']} o {$una_clase->subclase->id}"; // array con comillas pero entre las llaves o una claseListo.
Joe Armstrong, en una lista de correo:
The turn round time for a program was three weeks
- week 1 – write code on paper forms – send to computer center to be turned into punched cards
- week 2 – review punched cards, if ok send to machine
- week 3 – results
The compiler helpfully stopped at the first syntax error which got you back to week 1 – so if you had say ten errors in your program it would take 30 weeks to get it running.
This is a pretty good environment – teaches you not to make mistakes and to think first.
El mail entero vale la pena.
Leo en No-cost desktop software development is dead on Windows 8 | Ars Technica:
If you want to develop desktop applications—anything that runs at the command line or on the conventional Windows desktop that remains a fully supported, integral, essential part of Windows 8—you’ll have two options: stick with the current Visual C++ 2010 Express and Visual C# 2010 Express products, or pay about $400-500 for Visual Studio 11 Professional.
La tabletización, como parte de la guerra contra el ordenador personal y contra el mundo que éste hace posible sigue adelante haciendo un 2×1: a los desarrolladores los ata un poco más a la plataforma propia, y a los que no aceptan esa sumisión les hacemos pasar por caja.
