Here is a very optional #PHP command : try-catch-finally
The finally clause in a try-catch-finally is optional: it can be omitted and often is.
The catch clauses in a try-catch-finally are also optional: they can be omitted.
When the catch and finally clauses are all omitted, the try clause can also be omitted. Safely.
