[RESOLVED] Nested Function References

[RossC0]

Hi,

I get a parse error trying to call this code:

$this→getContext()→getDatabaseConnection();

Is there an ini setting that I need to be able to call nested functions ??

What do you mean by nested functions? In PHP 5 the above snippet calls a method getContext() on $this, and getContext() returns a reference to an object with a getDatabaseConnection() method. As far as I know this behaviour is can't be enabled or disabled in PHP 5 (it's not present at all in PHP 4).

However a nested function is a function within a function, e.g.

function myFunction()
{
  function myNestedFunction(){}
}

ok that answers one question:

In theory then this should be parsable: $this→getContext()→getDatabaseConnection();

[Shrike]

Yes it should be, what error do you get?

Unbelievable - parse error - due to the copy and paste of these little beauties:

→ should be ->

RossC0 hangs his head in shame... :o

Resolved flag? Under the Thread Tools dropdown, top o' the thread.
