Also, you need to close your <li> with </li> after. That should be
fixed, but you can confirm by looking at your page source. If you see:
<li><a href=""></a><br>
Then short tags are not enabled.

Hey all,
I've been Googling trying to find a JavaScript
list serve to post a question to, but have been,
embarrassingly, unable to find one.
Anyone on one they'd recommend or know of one?
Thanks

Not a list, but the peeps in #javascript on irc.freenode.net have
never once failed me when I was stumped.

see these archives is not much to brag about, hard to follow and hard to

Use google. Google is expert in finding weird information regarding stuff you
put in the search field.
I would also follow up on the read on filesystem handling on php.net if you
feel shorthanded regarding comparisons.

I have been using php's curl for quite a while now and it has never
allowed to run javascript... bummer! I read on an article
http://blogs.zdnet.com/Stewart/?p=627 that the new curl v6 allows this.
There are a few ajax sites that I would like to scrape, but they are a
pain to read through all of the functions to figure out how everything
is displayed. I'm hoping that with this addition to the curl library,
this could be more easily done.
Does anyone know when or if the javascript addition will be implemented
to php's curl?
Thanks,
bp

me thinks you have curl, http://www.curl.com confused w/ curl,
http://curl.haxx.se/ ;)
check the manual, http://us3.php.net/manual/en/ref.curl.php

HI
i think it is a bit difficult. CURL can actually help you get Response on a
cross Domain platform. Javascript dosenot.
Espesially Ajax is not cross domain for security reasons.

Setting a variable inside a function and making it global inside an
inner function doesn't work?
Right well I have created this function:
[code]
function getForumChildrenTree( $id )
{
$id = intval( $id );
$treeResult = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);
applyForumChildrenTree( $id );
}
[/code]
What this function does: Basically this function is set to an id of a
forum id, then theres a variable that stores an array. Then theres a
recursive function called "applyForumChildrenTree" to update the
"treeResult" variable, but it's not exactly working. For some reason
when I did print_r inside the "applyForumChildrenTree" the array is as
applied:
[quote]
Array
(
[forums] => Array
(
[0] => 3
[1] => 8
[2] => 5
)
[topics] => Array
(
[0] => 5
)
[posts] => Array
(
[0] => 5
)
)
[/quote]
Then inside the actual function "getForumChildrenTree" I tried
outputting the "treeResult" array using "print_r" after the recursive
function "applyForumChildrenTree" as follows:
[code]
function getForumChildrenTree( $id )
{
$id = intval( $id );
$treeResult = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);
applyForumChildrenTree( $id );
print_r($treeResult);
}
[/code]
and it showed me a blank array, (default array I created) as follows:
[quote]
Array
(
[topics] => Array
(
)
[posts] => Array
(
)
[forums] => Array
(
)
)
[/quote]
Is this a bug? I'm using PHP 5.2.4

Well you haven't defined anything global in your code, unless you did
inapplyForumChildrenTree(), in which case it needs to be global
everywhere that you want to use it as global.
Easiest way would just be to use it like this everywhere:
$GLOBALS['treeResult'] = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);

After a second look, probably a better alternate would be to have
applyForumChildrenTree() return the array, then use $treeResult =
applyForumChildrenTree( $id );

Please reply to the list.
Sure, your function can return an array if it's recursive. It returns
it to itself and uses whatever logic you need to add to the current
array or merge or remove or whatever. Regardless, I explained why you
aren't seeing the vars as global and a better way to do it using the
$GLOBALS array. I may be off but we would need to see the
applyForumChildrenTree() to know.

As I said in my first reply, its a "Recursive function".so I couldn't
return the array.

Yep I'm using globals, thanks :).
function getForumChildrenTree( $id )
{
$id = intval( $id );
$GLOBALS['treeResult'] = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);
applyForumChildrenTree( $id );
$treeResult = $GLOBALS['treeResult'];
unset($GLOBALS['treeResult']);
return $treeResult;

Good job.
Actually, if you used $GLOBALS['treeResult'] in applyForumChildrenTree()
then you could skip the:
$treeResult = $GLOBALS['treeResult'];
unset($GLOBALS['treeResult']);
return $treeResult;
and just:
return $GLOBALS['treeResult'];
or use $GLOBALS['treeResult']; somewhere later instead of returning it.
Also, I would be curious to see applyForumChildrenTree() because chances
are great that you can return an array and not use globals at all unless
it is "really" needed somewhere else in the app.

Setting a variable inside a function and making it global inside an
inner function doesn't work?
Right well I have created this function:
[code]
function getForumChildrenTree( $id )
{
$id = intval( $id );
$treeResult = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);
applyForumChildrenTree( $id );
}
[/code]
What this function does: Basically this function is set to an id of a
forum id, then theres a variable that stores an array. Then theres a
recursive function called "applyForumChildrenTree" to update the
"treeResult" variable, but it's not exactly working. For some reason
when I did print_r inside the "applyForumChildrenTree" the array
is as
applied:
[quote]
Array
(
[forums] => Array
(
[0] => 3
[1] => 8
[2] => 5
)
[topics] => Array
(
[0] => 5
)
[posts] => Array
(
[0] => 5
)
)
[/quote]
Then inside the actual function "getForumChildrenTree" I tried
outputting the "treeResult" array using "print_r" after the recursive
function "applyForumChildrenTree" as follows:
[code]
function getForumChildrenTree( $id )
{
$id = intval( $id );
$treeResult = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);
applyForumChildrenTree( $id );
print_r($treeResult);
}
[/code]
and it showed me a blank array, (default array I created) as follows:
[quote]
Array
(
[topics] => Array
(
)
[posts] => Array
(
)
[forums] => Array
(
)
)
[/quote]
Is this a bug? I'm using PHP 5.2.4
Well you haven't defined anything global in your code, unless you did
inapplyForumChildrenTree(), in which case it needs to be global
everywhere that you want to use it as global.
Easiest way would just be to use it like this everywhere:
$GLOBALS['treeResult'] = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);

After a second look, probably a better alternate would be to have
applyForumChildrenTree() return the array, then use $treeResult =
applyForumChildrenTree( $id );
-Shawn
As I said in my first reply, its a "Recursive function".so I couldn't
return the array.
Please reply to the list.
Sure, your function can return an array if it's recursive. It returns
it to itself and uses whatever logic you need to add to the current
array or merge or remove or whatever. Regardless, I explained why you
aren't seeing the vars as global and a better way to do it using the
$GLOBALS array. I may be off but we would need to see the
applyForumChildrenTree() to know.
-Shawn
Yep I'm using globals, thanks :).
function getForumChildrenTree( $id )
{
$id = intval( $id );
$GLOBALS['treeResult'] = array(
'topics' => array(),
'posts' => array(),
'forums' => array(),
);
applyForumChildrenTree( $id );
$treeResult = $GLOBALS['treeResult'];
unset($GLOBALS['treeResult']);
return $treeResult;
}

True, I could, actually I was trying something and my code is exactly
like that. :)

Shelley,
What code have you tried and what were your results?
What about searches on google or the archives here?

You can try searching the archives. Rasmus had an example a long time ago.
Although it requires APC to be installed. Maybe it's interesting.
