[PHP] Question about CREATE_FUNCTION
Dear list,
Does anyone know how the internals of create function works?
$test = create_function('blah','$arg,$arg2',$code);
Does it really create the function in $test; or creates it a global function
and references it to $test
And further more,
is it very SLOW?
Warm regards,
Emile Bosch

Re: [PHP] Question about CREATE_FUNCTION
Or, to actually prove your point in the original e-mail (I checked it and
you're right):
If you now try it won't do anything -- as you said, is the proper code.
Something worth mentioning is that even if you do
the former version won't work.

Why do you draw the conclusion you're misunderstood? We are unable to answer your question about speed -- so aren't we allowed to have a separate discussion derrivated from your question?

Re: [PHP] Question about CREATE_FUNCTION
I understand what you want to know (I dont know myself though) I dont see
why it should be significantly slower than any other function (unless you're
doing it millions of times in a row!!)
If it doesnt recommend using a different function in the manual, I would
keep using the one you're happiest with

Re: [PHP] Question about CREATE_FUNCTION
since you CAN'T create functions runtime, unles you are using an eval
expression
but that's even slower that create_function..
function bla() {
}
$test = "bla";
$test();
Is not solving the problem since, it doesn't create a function at RUNTIME it
only references a function..
(it references $test to the function pointer blä)
create_function <= Php command
creates a function runtime.
But thanks for all your time anyway!
Warm regards,
Emile

Ah, I thought you did disagree. Whatever. I misunderstood you, sorry
about that.
