php.net : search "foreach" :
As of PHP 5, you can easily modify array's elements by preceding
$value with &. This will assign reference instead of copying the
value.
<?php
$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
$value = $value * 2;
}
// $arr is now array(2, 4, 6, 8)
unset($value); // break the reference with the last element
?>
This is possible only if iterated array can be referenced (i.e. is variable),
References in foreach don't work the way you think they work. You will
still incur the copy. At least I did when I tested earlier today :)
Cheers,
Rob.

The peak memory usage when using references (or not) and using
foreach() vs array_walk() was the same in all my testing.
But surprisingly, the foreach() with references all round used the
lowest memory during the looping. The worse case was mixing reference
and value passing with array_walk().
My dataset was generated by reading the C:\PHP5 directory where the
keys are the directories and saving the data as an include
(var_export()-ing it).

Hi there.
the problem:
I want to disable mail() function in the one of virtual hosts' that
use PHP(I use mod_php for apache2), and regarding to the
http://www.php.net/manual/en/ini.core.php#ini.disable-functions I
can't use directives like php_value, etc, because value of
disable_functions can be set only in php.ini, but I don't want to
disable mail() on the all of my virtual hosts, just on one.
the question:
Can I use different php.ini for virtual hosts, in my case I want to
use php.ini for one host, where disable_functions = mail will be.
Here backgrounds:

i dunno about overriding the entire php function, but you can disable
mail() in the virtualhost section of your apache config with the
following line:
php_value disabled_functions mail

What about disabling mail altogether in favour of a mailer that requires
a login to use? That way, you can easily set quotas and keep track of
all emails sent by each client on your hosting.

i'm not entirely sure what you're suggesting here, but i don't think
it will work for me as one of the things i want to do is set up a
"test" directory, inside which i might have subdirectories with more
test routines, so i can't guarantee *anyone's* position relative to
the top of the "proj" directory.
i might even want to write PHP scripts and place them quite some
distance from the "proj" directory but still want to include utility
scripts from the "proj" directory. based on how i've done this with
shell and makefile-based projects in the past, the easiest solution
seemed to be to simply demand that users set a single environment
variable identifying the location of the "proj" directory, and base
everything off of that by extending the include path. at that point,
everything falls into place and all include/require references work
relative to the top of the "proj" tree.
i think that's the direction i'm going to go, unless someone has a
compelling reason not to. thanks.

IOW, you want to point into the first project's test directory from
other projects when you can't know the relative paths between those
projects?
I suspect you will have to manage that on a machine by machine basis,
unless you can convince the entire development team to create a common
directory structure that encompasses all projects.

let me emphasize that the layout of the entire "proj" directory will
be consistent across all users and all machines since it will
represent a single SVN checkout, so that's not an issue. of course,
anyone will be free to check it out anywhere they want but once they
do, its structure will be the same across all checkouts.
that's why i think the easiest solution is to define a single
environment variable (say, PROJ_DIR) that anyone can set depending on
where they do the checkout, the PHP code itself will (somehow)
initially consult that variable, and all inclusion from then on will
be based on that. piece of cake, no?
in fact, developers are free to do more than one checkout, work on
them independently, and change PROJ_DIR depending on which one they
want to pick up for their code.
does that more clearly explain what i think the right approach is?

I've browsed wikipedia, sf.net and google for code & papers on what is
commonly known as NLP.
I haven't found thesaurus software for native php/mysql, wordnet which
is apparently the leader, provides os-native apps, and "db files"
without db structure and not in any sql format (looks like cvs without
the commas but i'm not sure yet).
When i asked princeton staff about sql releases they simply replied
"we dont do sql here". Which i find a bit strange..
Easiest thing for me to do is write a conversion script that puts
their "db files" in mysql, and work from there.
My search on sf.net turned up empty too, all of the projects with
relevant descriptions have just the name regged, no code releases.
>From reading http://www.go4expert.com/forums/showthread.php?t=35,
"Introduction to Natural Language Processing(NLP)", i gather that NLP
as it is results in much ambiguity on several levels of it's
operation.
It's an interesting problem though, and probably a profitable one, so
i'm going to spend some time trying to come up with something better
from scratch.
