Don't worry I know how variable work internaly into Zend Engine ( for those
who want more info, Derick Rethan's got a good pdf file explaining that
process here :
http://derickrethans.nl/files/phparch-php-variables-article.pdf , Derick, if
you here us, feel free to come in that conversation ;-) )
But as said, that is an internal PHP behavior that, in my opinion, should be
explained in the documentation.
Now consider this :
?php
$a = array(One,Two,Three);
$b = $a;
next($b); // go to the second key of $b
foreach ($a AS $k=$v) {
if (current($a) == current($b)){ // I want you to stop on the second key
of $b
var_dump(current($b)); // will never get echoed, as current($a)
always returns StringOne
break;
}
}
?
Due to COW, using current($a) makes PHP making a real copy of $a array to
work on it, and current($a) is always at its first place ( StringOne)
because PHP works on the real copy, and its own array iterator. In that
example, the if condition will never be satisfied.
Ok let's make it funnier now :
?php
$a = array(One,Two,Three);
$b = $a;
$c = $a;
next($b);
foreach ($a AS $k=$v) {
if (current($a) == current($b)){
var_dump(current($b)); // works : outputs StringTwo
break;
}
}
var_dump(current($a)); // output StringTwo
?
Aha, now if I hold a reference to $a variable ($c here ), it looks like COW
doesn't show the same behavior as before.
Foreach seems to keep working on a lazy copy of $a, and so it moves the
real $a internal iterator as shown here. The if condition is verified and
the last script line clearly shows that $a internal pointer has been
manipulated by the foreach loop.
We see here that working on internal iterators using foreach is not really
recommanded. I have never needed to do that in a real developpement as well,
I'm just experimenting PHP behavior, but I think that the official
documentation should warn users about such behaviors.
For information : it's actually tested, for me, on PHP 5.2.3 running on a
Windows server. Error Reporting is set to E_ALL.
cheers.

i agree; at least i have never had a need to determine the current index
of the internal array pointer in nearly 3 years working w/ php.
although it is somewhat interesting to experiment w/ the language to see
how it behaves :)

[PHP] Hi. I need your help here
Hi. I came across your contact info at php.zend.com and was hoping you could
help me out with this question.
I recently installed Rubberwall10, a free software that protects from
hotlinking and although I managed to installed the software correctly at my
site, I came across the fact that when I tried to download an image from the
site to my computer, the image came out with 0 kbs.
Someone who also installed the software made a comment on the internet
stating he solved the problem adding a trim function to three of the variables
in the filescrapper.php file.
My question to you is, how can I do that. I am not familiar with php,
although I have understood some minimal basics. Adding trim function to $ct,
$webaddress and $wantedfilename seemed to have solved the problem according to
the user who solved the problem but did not specify how he did it. Can you tell
me how I can add trim function to the above three variables?. Your help is
greatly appreciated. The code is below. Thanks. John

[PHP] Setting Different Temp Directory for Different Application Users
Hi All, I want to set different temp directory to every users of my application. Is it possible. TEMP_DIR is only configurable at system level, so I can do it only in PHP.INI or in apache as PHP_VALUE. Any Idea how this can be achieved using combination of things? Thanks in Advance.

[PHP] file_get_contents crash, if file is bigger than memory_limit
I really dont know, if this is the right board for this... but i think, i
have to write it down.
Please throw an error, if file_get_contents cant read a file because
memory_limit overflow!
I´ve programmed a tool parsing checksums from large files. Because i have to
manage header-offsets, i have to read the files using file_get_contents.
(This should be the fastest way for this task says the manual... right!)
The problem is, that if the memory_limit in the php.ini is set to 64MB, and
the file read in by file_get_contents is bigger than 64MB, file_get_contents
crashes without an EXCETPION. This crash cant be catched!
I want handle this this way:
try{
$data = file_get_contents($file);
}
catch (MemoryLimitReachedException $e){
// try the same using a while loop reading the data! (This works!)
}
Hope, there is a solution for this.
Thank you.

I'm not really knowledgeable about IIS, but if you can see php code in the browser it usually means the web server hasn't been set up to execute php rather than just serving it. Check your config to make sure it knows to pass *.php requests through php5 rather than just sending the page back directly. How you do this on IIS is beyond me I'm afraid.

[PHP] PHP, mbstring, UTF-8 and indexing strings
Just a simple question (with a simple answer, hopefully): how can I access
character x of a utf-8 encoded string? i.e. how would I get this to work:
for($x=0; $x strlen($utf8); $x++)
echo character {$x}: . $utf8{$x};
Keep in mind that I have strlen overloaded by mbstring, and this is
necessary for my purposes because I need to do work on each character. Also,
by character I mean, for example: 我.
Thanks,

memory_limit overflow!
go read the archives of [EMAIL PROTECTED] for numerous reasons why that
it not going to happen.
I´ve programmed a tool parsing checksums from large files. Because i have to
manage header-offsets, i have to read the files using file_get_contents.
given that your own comment in the example below states while loop reading
the data! (This works!) I can't see why you *have* to use file_get_contents()
have you tried filesize() and chcked the result is less than memory_limit?
(This should be the fastest way for this task says the manual... right!)
The problem is, that if the memory_limit in the php.ini is set to 64MB, and
the file read in by file_get_contents is bigger than 64MB, file_get_contents
crashes without an EXCETPION. This crash cant be catched!
why do you think it should throw an exception? it won't, especially not a
particular class of exception that you made up o the spot.
php errors and exceptions are 2 different things, before going any
further you should read up on both so that you understand the difference.
I want handle this this way:
try{
$data = file_get_contents($file);
}
catch (MemoryLimitReachedException $e){
// try the same using a while loop reading the data! (This works!)
}
Hope, there is a solution for this.
Thank you.

[PHP] Display paragraphs from a mysql db
hi all,
I have a news section on a website that im coding that isnt displaying
properly. Every paragraph in each news post is being displayed as one big
paragraph. how can i display my paragraphs in proper form? The field the
news story is stored in is set as longtext.
here is a link to view.
http://area51.chalkthree.com/index.php?pg=3
the first update shows what im having an issue with. each item in the
numbered list should be on a seperate line. there are some line breaks as
well for new paragraphs that arent displaying properly.
here is the code i have:
while($myrow = mysql_fetch_array($newsresults))
{
print br;
print $myrow['news_topic'];
print ;
print $myrow['news_author'];
print;
print $myrow['topic_date'];
print br;
print $myrow['news_message'];
print br\n;
}

well you're the only one who might.
given that your own comment in the example below states while loop reading

file_get_contents()
Hm, strange answer, i think. Do you ever have used the file functions of php.
Why the developers of php say, that file_get_contents is the way to read
files? Maybe because its faster then a while contruct.
was it ever said that it's the only way?
Or am i wrong?
have you tried filesize() and chcked the result is less than memory_limit?
Thats an good answer, but i think, the can also be done by php internally +
throwing an exception :-)
ah so you were there when php core developers decided that BC would be
completely broken and
all core errors would be throw as exceptions? me, I must have missed that.
php exceptions are generally a user level construct - the php core generates
error not exceptions
(with the exception of a few OO based php extensions [php intended])
you might consider that you probably need to work with a tool for a little
longer than
5 minutes before being in a position to determine whether a change to the tool
is possible or
desirable. php is used by 100,000's of people changing the language is not
something
you do 'just like that'
Maybe i have to read the [EMAIL PROTECTED] strange, this is like the
hitchhiker. Read the hidden manual!
Never head before of this internals
if you are a php core developer. i´m not,
I'm not a core developer either, but that doesn't stop me following development
issues
and discussions on their mailing list.
i´m a stupid little programmer!
you said it not me, guv.
why do you think it should throw an exception? it won't, especially not a
particular class of exception that you made up o the spot.
Never head of Pseudocode, examples?? Dont know, how to name this Exception...
if you have an better name... WhateverException
Ok, das musste raus... ist nicht so gemeint :-)
I'm dutch, I don't speak german - I can guess at the meaning of the above but
for the sake of
everyone else stick to english, the language used on this list, please.

Also browsers don't deal with white space the way a word processor does. Very roughly speaking, your browser will display only one space for one or more whitespace characters. if you want spaces, use css, nbsp; or br HTH Ray snip code -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Aggressive PHP Smart Caching
Alexander, sorry to see nobody has replied to your post, im sure you worked very hard on the cache system and are eager for feedback.. so to me it looks like youve introduced a somewhat new style of caching here (though im sure there are other such approaches); for instance i know of 2 main uses for caches at this time [as caching pertains to php]. 1. caching php intermediate code 2. caching application variables both of these caching techniques are designed to overcome limitations of the language as it ships out of the box, more or less; afaik. it appears you are interested in caching the output of php scripts, which is, i suppose, a third technique that could be added to the list. so i have a criticism about your system and a couple questions as well. *criticism* - why cache script output on disk? if a fast cache is your goal, why not store the result of script output in memory rather than on disk; that would be much faster *questions* - how does your cache system know when cached output is stale and allow fresh contents to be delivered from the original script rather than being served from the cache? - why purge cache contents after 24 hours? im on the memcached mailing list, and recently they were discussing artificially resetting the cache; several people said they let memcahe run for months on end. -nathan On 6/18/07, Alexander Romanovich [EMAIL PROTECTED] wrote: I'm a PHP developer looking for feedback on a caching approach I put together recently.

Exactly, but by not having them by default it makes it harder for you to accidentally make use of them. Either way, whether PHP holds your hand or not, they made a design choice to not have application variables, and as such that IS why they are not part of the language by default.
