Hi all,
I've posted this in "Declare minimum PHP version required?" thread.
I thought it my be better to have new thread for this.

I have concluded that these checks should be done by new assert()

I think of another idea for declare(). Current declare() has 'tick'.
How about have hooks 'pre_hook' and 'post_hook'?
It works like tick. Tick executes registered function/code by execution
cycle.
'pre_hook' and 'post_hook' executes registered function/code before
function call
and after function call. Something like
declare(pre_hook=TYPE) { some_useful_code }
declare(post_hook=TYPE) { some_useful_code }
Where TYPE is 0=none, 1=user, 2=internal, 3=both.
'none' is for to use hook inside function body.
These hooks are executed like
function foo() {
// pre_hook hook here
some useful code
// post_hook hook here (executed for all 'return')
}
This is useful for user land PHP debugger/profiler as well as pre/post
condition checks. We have dbg, but it's nice to have hook in user
land for simple debugging and profiling also. It may be convenient if
hooked functions/methods can be specified, but it might be headache
with namespace. Simply hooking all calls might be simpler as it does
not have to be fast.
Or declare() may be used inside functions.
function foo() {
declare(pre_hook=0) { some useful code }
declare(post_hook=0) { some useful code }
body
}
There are many way for hook design.
Just an another idea for declare().
Since declare() is compiler directive, INI is needed for enabling/disabling
for all files.
Any comments for this feature?
