Okay, I'm probably really stupid, but I can't figure this out. I'm getting the
error:
Fatal error: Function name must be a string in .../pages-stage/loginresp.php on
line 205
(which is the xml_set_element_handler() call)
with this code:
function startElement($parser, $name, $attrs) {
global $value;
$value = "";
}
function endElement($parser, $name) {
global $value, $bypass, $status;
....
}
function charData($parser, $data) {
global $value;
$value = $data;
}
if (!isset($_GET["consentResp"])) {
...
} else {
...
}
// Fallthru do getPresence
// Okay, user is auth'd, now do getPresence to get members of BL
$resp = doGetPresence($devId, $authToken, $baseUrl);
// sigh - strip HTTP metadata
$resp = strstr($resp, "<?");
// Do XML parse - sets status, handles BL data if present
$xml_parser = xml_parser_create();
$xml_set_element_handler($xml_parser, 'startElement', 'endElement');
$xml_set_character_data_handler($xml_parser, 'charData');
$xml_parse($xml_parser, $resp, true);
$xml_parser_free($xml_parser);
Any ideas? I've tried the line with single quotes, double quotes and no quotes,
and various other odd attempts to figure it out. I'm totally baffled.
Many Thanks (in advance),
Bruce Steinback

Uhm, why do you have a $ before xml_set_element_handler?

> $xml_parse($xml_parser, $resp, true);
> $xml_parser_free($xml_parser);
And also before above functions?

Tedd,
Finally, I can give you an answer! :)
You can use html tidy. I did this before the php tidy function was fully
implemented, so I don't know the syntax for that. But using tidy from the
command line you can set have it either correct errors (probably not what
you want) or just have it return an error flag and log the errors.

Subject: [PHP] Check for well formed html
Hi gang:
I have a client who wants to include html tags in his CMS.
I know that I can limit what tags he can use, but how can I check if
the text is well formed with the tags permitted before storing it in
his CMS?
Cheers,
tedd

$timestamp = $timestamp + 86400;
A timestamp is a number of seconds and there are 86400 seconds in a day.

As far as I understand it is only possible to create a DateTimeZone
Object from a string, which describes the timezone.
On the other hand it is not possible (at least I did not find any
possibility) to get the users tz string, it is only possible to get the
current UTC offset. (via JavaScript or by doing some magic with the
users IP)
I wonder if there is a possibility to get a list of possible timezones
with a certain offset. I could extract this list from the
timezone_abbreviations_list or check the offset for every item in the
timezone_identifiers_list, but those solutions seem far too complicated
and slow.
So is there a function like
array timezone_guesses_get(int)
where int is the UTC offset in hours and array is a list of possible
timezone names.
thanks,
Norbert

Nice to hear that!
If you expect heavy traffic on the site using that script you might want try
to save some DNS and http connection overhead by stating the url with
http://localhost/ and so on. Given that the server's OS is unix based, it
may also work to execute the php-script like a shell script if the php
environment is set accordingly.
In case of a image processing script, this may take a huge load of work away
from your apache or wahterver server, and restrict it to the php processor
only.
(the data stream won't be routed over the internet deamon and the webserver
on port 80)
In order to do so, try
$buffer = `php /var/www/thescript.php`; // or whatever location your script
is in ...
Instead of
$buffer = file_get_contents("http://localblah...";);
But if it's a rented server, apache overhead isn't your concern, so go on
and let your provider worry about it! :-D

Which will most likely point to a different virtual host and cause you
even more problems trying to track it down.

You've got a point about that.
Try
<?php
echo file_get_contents("http://localhost/path/to/webdir";);
?>
First ... If you see your own webpage it's okay, else don't mess with it.

Hi
In the past, I always used mysql_insert_id() and never had a problem,
but now that I'm using PDO, I'm finding that it always returns zero.
The tables are identical between the two methods but where
mysql_insert_id works $pdo_connection->lastInsertID() doesn't.
The PDO documentation states that you need to feed lastInsertID
something called a "sequence object." I'd never heard of those before
so after some reading here http://www.mckoi.com/database/
SQLSyntax.html#7 it looks like you have to create these yourself .
But MySQL tables already seem to have a built-in sequence (as
evidenced by the auto_increment flag when creating tables) and
creating another one for a given table could lead to id collisions.
So basically, the question is: Is it possible to get valid
"lastInsertIds: using PDO with a MySQL database that mirrors the
behavior of mysql_insert_id?
Thanks for any help
Ken
Here' the function.
The lastInsertID call comes in the 'else' branch of the "if (strpos
($query, 'insert') === false)" test
function query_database($inQuery)
{
$query = $inQuery;
$coersions = null;
$object_key = null;
$group_by_key = null;
if (is_array($inQuery))
{
$query = $inQuery['query'];
$coersions = $inQuery['coersions'];
$object_key = $inQuery['object_key'];
$group_by_key = $inQuery['group_by_key'];
}
try
{
// determine query type
if (strpos($query, 'insert') === false)
{
$rows = array();
$rowCounter = 0;
foreach ($this->db->query($query, PDO::FETCH_NAMED) as
$row)
{
$rowFields = array();
$recordKey = $rowCounter;
foreach ($row as $key => $value)
{
// remember this key if it matches the
user specified object key
if (($object_key != null) && ($key ==
$object_key))
$recordKey =
$value;
// perform user specified coersions
if ($coersions != null)
$value =
$this->coerce_value($value, $coersions[$key]);
$rowFields[$key]
= $value;
}
// perform grouping if requested
if ($group_by_key == null)
$rows[$recordKey] =
$rowFields;
else
{
$groupKey =
$rowFields[$group_by_key];
if ($rows[$groupKey] == null)
$rows[$groupKey] =
array();
$rows[$groupKey][] =
$rowFields;
}
$rowCounter++;
}
return $rows;
}
else
{
// next line prints OK on inserts
echo 'query type was: insert<br>';
// but this always returns zero
return ($this->db->lastInsertId());
}
}
catch (PDOException $error)
{
print "Error!: " . $error->getMessage() . "<br/>";

Disregard.
After more head scratching I found that I was branching to the
'insert' handler without calling this->db->query($query).

I have two tables that share product codes to relate data.
One table is called IMAGE, and another one is called the PRODUCT.
There are more than one image for every product, for example product
code 1122 will have 3 images and 4938 will have 5 images within the
IMAGE table. Since all my product information is stored in PRODUCT table
except for the image file names (e.g. 1122_1.jpg, 1122_2.jpg or
4938_1.gif), I have to build the following query: SELECT * FROM PRODUCT,
IMAGE WHERE PRODUCT.productcode = IMAGE.productcode. However, this
causes a little problem. When I print out all the product information
with its images, more than one copy of a product is printed out (because
of multiple images for each product). I'm still looking for a way to
build a query string so that I could have only one image displayed per
product (so that a user can click on the product to view more images).
Do you know how this problem can be best approached?

You can use a group by clause to cause the result set to normalize on
the grouping criteria (productcode would be a good candidate).

Rob.
