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($a)
always returns String"One"
break;
}
}
?>
Due to COW, using current($a) makes PHP making a "real" copy of $a array to
work on it, and current($a) is always at its first place ( String"One")
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($b)); // works : outputs String"Two"
break;
}
}
var_dump(current($a)); // output String"Two"
?>
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 :)

If that still doesn't work, try a var_dump($_POST) at top of your
script, and see if there's anything inside.

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.

But why is the php code showing just like my code at the top when i right
click the webpage and view source, i suspect this must be a php.ini setting

Yes, it might be.
That's why I asked you if you had short tags enabled or not, and that
you can better use <?php instead of <?.

Yes, short tags can be enabled in php.ini, and <?php is in your script ;)

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,

I'm really looking into using PHP as an all-round scripting language.
I'm looking for a native looking UI toolkit, which takes PHP-GTK out the
question.
I've seen wxWidgets but I can't find any bindings for PHP, unless
anybody knows of any that I can't find?
Or, if anybody knows of any other native UI toolkits available for PHP?
At least native linux and windows look.

if your looking to post a feature request then there is no list for that
- the bug database would be the place to do it ... but please don't bother the
devs with your feature request - it won't happen for reasons that are public
record.

go read the archives of [EMAIL PROTECTED] for numerous reasons why that
it not going to happen.

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?

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.

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";
}
