[PHP] Two ways to obtain an object property
This relates to a minor dilemma I come across from time and time, and
I'm looking for advice on pros and cons and best practice. Last night I
encountered it again.
Within a site I have a User object, and within page code would like to have
if ($crntUser-isASubscriber) {...}
There seems to be two ways to handle this:
I can have a User object method getSubscriberStatus() which sets
$this-isASubscriber. But to use this I would have to run the method
just before the if statement.
Or I could have a method isASubscriber() which returns the result,
meaning the if statement should be
if ($crntUser-isASubscriber()) {...}
While this is last night's specific example, I seem to face the
method-setting-variable or the method-returning-result-directly decision
quite often.
Is either of these approaches preferable, or does it simply not matter?
Thanks

Compiled when execution hits them. You can prove this by trying to
conditionally include a file with a syntax error: if (false)
include('script_with_syntax_error.php'); won't cause an error.
Good idea.
Secondly, are include files that are referenced, but not used, loaded
into memory? I.e Are statically included files automatically loaded
into memory at the start of a request? (Of course those where the
name is variable can only be loaded once the name has been
determined.) And when are they loaded into memory? When the
instruction pointer hits the include? Or when the script is initially
loaded?
If your include file is actually included, it will use memory. If it
is not included because of some condition, then it won't use memory.
I wonder if that's the same when a cache/optimiser is used. Probably.
Maybe I'll check.
Are included files ever unloaded? For instance if I had 3 include
files and no loops, once execution had passed from the first include
file to the second, the engine might be able to unload the first
file. Or at least the code, if not the data.
If you define a global variable in an included file and don't unset it
anywhere, then it isn't automatically unloaded, nor are
function/class definitions unloaded when execution is finished.
Once you include a file, it isn't unloaded later though - even
included files that have just executed statements (no definitions
saved for later) seem to eat a little memory once, but it's so minimal
that you wouldn't run into problems unless you were including many
thousand files. Including the same file again doesn't eat further
memory. I assume the eaten memory is for something to do with
compilation or caching in the ZE.
Thirdly, I understand that when a request arrives, the script it
requests is compiled before execution. Now suppose a second request
arrives for the same script, from a different requester, am I right
in assuming that the uncompiled form is loaded? I.e the script is
tokenized for each request, and the compiled version is not loaded
unless you have engine level caching installed - e.g. MMCache or Zend
Optimiser.
I think that's correct. If you don't have an opcode cache, the script
is compiled again for every request, regardless of who requests it.
IMO, you're probably better off with PECL/APC or eAccelerator rather
than MMCache or Zend Optimizer. I use APC personally, and find it
exceptional - rock solid + fast. (eAccelerator had a slight
performance edge for my app up until APC's most recent release, where
APC now has a significant edge.)
Thanks - that's useful to know.
Fourthly, am I right in understanding that scripts do NOT share
memory, even for the portions that are simply instructions? That is,
when the second request arrives, the script is loaded again in full.
(As opposed to each request sharing the executed/compiled code, but
holding data separately.)
Yep, I think that's also correct.
Fifthly, if a script takes 4MB, given point 4, does the webserver
demand 8MB if it is simultaneously servicing 2 requests?
Yep. More usually with webserver/PHP overhead.
Lastly, are there differences in these behaviors for PHP4 and PHP5?
Significant differences between 4 and 5, but with regards to the
above, I think they're more or less the same.
Thanks Jon. So in summary: use a cache if possible. Late load files to
save memory. Buy more memory to handle more sessions. And it's
conceivable that when caches are used, different rules may apply.

As far as I know, the files are only loaded as execution hits them.
If your code contains:
?php
if (0){
require 'foo.inc';
}
?
Then foo.inc will never ever be read from the hard drive.
You realize you could have tested this in less time than it took you
to post, right?.
:-)
I don't know the extent to which the engine optimises performance, and I
know very little about how different versions of the engine deal with
the issue, but I guessed it depended on the behaviour of the engine,
cache and maybe optimiser, and know/knew I don't know enough... My
thinking: for dynamically linked files, one speed optimisation is to
load the file before it's needed, at the expense of memory, while
continuing execution of the loaded portions. It's easy to do if the
filename is static. The code may never be executed, but still takes up
space. Some data structures can also be pre-loaded in this way.
Are included files ever unloaded? For instance if I had 3 include
files
and no loops, once execution had passed from the first include file to
the second, the engine might be able to unload the first file. Or at
least the code, if not the data.
I doubt that the code is unloaded -- What if you called a function
from the first file while you were in the second?
I agree it's unlikely, but it's feasible if coded is loaded whenever
required. Especially if data and code are separated by the engine, and
that's quite likely because of the garbage collection.
Thirdly, I understand that when a request arrives, the script it
requests is compiled before execution. Now suppose a second request
arrives for the same script, from a different requester, am I right in

for each request, and the compiled version is not loaded unless you

engine level caching installed - e.g. MMCache or Zend Optimiser.
You are correct.
The Caching systems such as Zend Cache (not the Optimizer), MMCache,
APC, etc are expressly designed to store the tokenized version of the
PHP script to be executed.
Note that their REAL performance savings is actually in loading from
the hard drive into RAM, not actually the PHP tokenization.
Skipping a hard drive seek and read is probably at least 95% of the
savings, even in the longest real-world scripts.
The tokenizer/compiler thingie is basically easy chump change they
didn't want to leave on the table, rather than the bulk of the
performance win.
I'm sure somebody out there has perfectly reasonable million-line PHP
script for a valid reason that the tokenization is more than 5% of the
savings, but that's going to be a real rarity.
Thanks - that's really useful - I didn't realise that the bulk of the
saving wasn't in tokenising.
Fourthly, am I right in understanding that scripts do NOT share
memory,
even for the portions that are simply instructions? That is, when the
second request arrives, the script is loaded again in full. (As

Yes, without a cache, each HTTP request will load a different script.
Do you know if, when a cache is used, whether requests in the same
thread use the same in-memory object. I.e. Is the script persistent in
the thread?
Fifthly, if a script takes 4MB, given point 4, does the webserver
demand
8MB if it is simultaneously servicing 2 requests?
If you have a PHP script that is 4M in length, you've done something
horribly wrong. :-)
Sort of. I'm using Drupal with lots of modules loaded. PHP memory_limit
is set to 20MB, and at times 20MB is used. I think that works per
request. All the evidence points to that. So 10 concurrent requests,
which is not unrealistic, it could use 400MB + webserver overhead. And I
still want to combine it with another bit of software that will use 10
to 15MB per request. It's time to think about memory usage and whether
there are any strategies to disengage memory usage from request rate.
Of course, if it loads a 4M image file, then, yes, 2 at once needs 8M
etc.
Lastly, are there differences in these behaviors for PHP4 and PHP5?
I doubt it.
I think APC is maybe going to be installed by default in PHP6 or
something like that, but I dunno if it will be on by default or
not...
At any rate, not from 4 to 5.
Thanks.
Note that if you NEED a monster body of code to be resident, you can
prototype it in simple PHP, port it to C, and have it be a PHP
extension.

[PHP] How does the Zend engine behave?
Hi,
I'm using PHP 4.x and I'm trying to understand a bit about memory usage...
Firstly, when I say 'include files' below, I mean all forms, include,
require and the _once versions.
That said, when a script runs and it's made of several include files,
what happens?
Are the include files only compiled when execution hits them, or are all
include files compiled when the script is first compiled, which would
mean a cascade through all statically linked include files. By
statically linked files I mean ones like include ('bob.php') - i.e the
filename isn't in a variable.
Secondly, are include files that are referenced, but not used, loaded
into memory? I.e Are statically included files automatically loaded into
memory at the start of a request? (Of course those where the name is
variable can only be loaded once the name has been determined.) And when
are they loaded into memory? When the instruction pointer hits the
include? Or when the script is initially loaded?
Are included files ever unloaded? For instance if I had 3 include files
and no loops, once execution had passed from the first include file to
the second, the engine might be able to unload the first file. Or at
least the code, if not the data.

So in between: /* Terminate encryption handler */ mcrypt_generic_deinit ($td); /* Initialize encryption module for decryption */ mcrypt_generic_init ($td, $key, $iv); you store and retreave from the cookie both $iv and $td. $key must be on your server. $iv must be some random stuff that changes between encryption and decryption (between sessions).

Your best bet, leaving the most visible way of tracing the steps on any authorization, would be to save the returned string to a file. Open the file and pass the handle to CURL_SETOPT like curl_setopt($ch, CURLOPT_FILE, $return_data_fp); Then have your script parse the data and output to the user appropriately. Alternately, you can set RETURNTRANSFER and put the string in a variable, like curl_setopt($ch, RETURNTRANSFER, 1); $return_data = curl_exec($ch); but then the variable is transient and you have no record of the transaction.
