[PHP-DEV] file_get_contents from HTTPS on Slackware 13.1
Hi all, we've bumped into a possible bug where file_get_contents() returns empty string if we try to get contents from HTTPS source. This error only occurs if PHP is compiled with --with-curlwrappers. Funny thing is this only happens on slackware 13.1, but not on 13.0 or older. I've checked ./configure and make output and they are almost identical, strace does not return anything meaningful. Environment is highly controlled by configuration management, software is built in the same way, except underlying OS versions (and very basic libs and tools versions) differ. Two questions: 1. Do any of you guys have any idea about this? 2. How to continue exploring deeper to discover what actually this error is all about? Regards, b.

[PHP-DEV] Exceptions for method on non-object rather than fatal (desired feature?)
Hi list,
I am aware this question might have been discussed to death but I did
some googling on $subject and watched the bug/feature tracker and it
seems most entries on this issue are old and unanswered.
Is there a design decision or hard-to-overcome engine limitation which
prevents turning method-on-nonobject into a catchable Exception? Or did
just nobody step up and provide a patch?
Rationale:
In another language/framework context I did a lot of chained/nested
stuff like this:
$granny_name = $baby-getMother()-getMother()-getName();
In PHP I would rather do
$mother = $baby-getMother();
if ($mother) {
$granny = $mother-getMother();
if ($granny) {
$granny_name = $granny-getName();
}
}
because I have no way to catch if $mother or $granny cannot be retrieved.
If it's generally welcome I'll try and supply a patch.
(Now let's hope this doesn't start something evil.)

Hi Martin,
First of all, thank you for your rapid response but it doesn't address
my question (or at least the question I intended to ask)
of course there is always a way to script around issues rather than
adressing them. I just want to know if the change would be desired. I
have code around which does exactly this, check on all levels of all
possible combinations. Semantically, this is nonsense and it bloats the
code. It's just a requirement because currently PHP handles this as
non-recoverable fatal.
I see no reason why it would be not desirable to have PHP raise the
exception rather than putting more or less repeating code snippets all
around the place. That is why I am asking.

Re: [PHP-DEV] [RFC] Enum proposal (yet another)
Right, but enums could possibly be a lot richer than class constants are
now.
They could be a type where the only values are what's defined in the enum.
This could be used with type hinting:
enum Foo {
A,
B,
C
}
function bar(Foo $x) {
// ...
}
There'd be no need to do any manual checking that $x is a valid value.
Perhaps enum values could also be casted back to strings:
(string)Foo::B; // B
Sure, this is the kind of stuff that's possible in other ways already, but
first class support always helps.

Can you explain how this is better or functionally different from the behavior
of APC? APC caches bytecode this way too. Unless I've horribly misunderstood
something, when you include the file APC uses the cached bytecode as long as it
is available and the file was not since modified. If the file was modified APC
recompiles it and caches the bytecode. Sounds like the same net result to me,
except that APC is less complicated, requires no code changes, and
automatically clears its own cache.

There is also apc_bin_dump() and apc_bin_load() if you absolutely must
have something stored on disk, but assuming you are interested in the
performance aspect here, you don't want to be loading anything from disk
on a per-request basis. If the interest is along the lines of being able
to distribute obfuscated binaries or something, then this is completely
the wrong approach because it is trivial to reverse engineer unless you
add an encryption layer on top of it.
I think one thing that people miss when comparing the php compile phase
to java/c/c++ compilation is that compiling a php script to opcodes is
super fast because we don't do complicated optimization passes or any of
those things, so the performance you gain by only skipping the
compilation phase isn't actually that much unless you combine it with
also caching the op_arrays, function and class tables in memory.
Imagine needing to compile a C++ program on every request? That just
isn't feasible. Without an opcode cache, the PHP compiler runs on every
request and it is fast enough for millions of sites out there.
