How does the GOTO implementation handle this
script1.php
<?php

do_some_stuff();
include script2.php;

label:
   echo "Hello"
?>

script2.php:
<?php
   declare_some_funcs();
    .... some code ...
    if (some_cond) {
       goto label;

[PHP-DEV] PHP 5.0.1

As I mentioned about a week ago, I'd like to roll 5.0.1 (mainly due to the 
auth bug) and some other fixes.
I was thinking of rolling this minor release tomorrow or Tuesday. If you 
have any bug fixes you'd like to make in, please let me know. There's no 
problem with delaying it somewhat more...
Andi

Included files are actually separate execution scopes (even though they're
shared data scope).  So the implementation referenced originally would raise
an error saing that 'label' is an undefined label.

Re: [PHP-DEV] GOTO operator

i'm just piping up that i'm a strong +1 on goto, its immensely useful
for code generators, like for example a gui application that wanted to
generate some type of php code.

also, when you start quoting djikstra in a php context, you've lost.  

goto is fine, fight the power!

Re: [PHP-DEV] GOTO operator

I'm starting to like goto more and more :)
At least it's a simple concept as opposed to using/scoped which make me dizzy.

Hehe, I think scoped could be pretty useful, though.

Cheers,

Re: [PHP-DEV] GOTO operator

Well in general if you have an object and leave the function which 
instantiated it, it'll be destroyed (unless you hold a reference to it from 
some global, in which case you probably don't want it to be destroyed). I 
don't think it has to be more fine-grained than that.

Can you explain why it makes no sense to use them in procedural code?  It 
makes perfect sense for me, and they render 100.0% of the examples shown on 
internals <at>  redundant...

Re: [PHP-DEV] PHP 5.0.1

I saw Dmitry commit several fixes to SOAP extension but I didn't see them
merged. Maybe they should be.
