Has anyone had any experience with this? Is there a simple, basic utility

I was kind of hoping I could avoid developing it myself.
cURL should be able to help you with that :)

In case you have no control on the other URL, then CURL is probably your
best solution.
Otherwise, a better way to do it is probably to interact with a web service
installed on the other website.

Is there any PHP's framework for developing a marketplace site ?
Not totally sure what you mean by "a marketplace site", but if you mean
an ecommerce site (online shop) then please search the list archives -
this topic comes up a lot here and has been discussed at length.

Hello everybody,
An year ago I was playing with the SimpleXML in php and found some issues
and abandoned php5 for a year. Now I'm back to it and I found that the
issius are still there.
Here is the first one - how one can find does a SimpleXMLElement has child
nodes?
Here is an example:
--------
$str = '<rootnode><subnode></subnode></rootnode>';
$x = new SimpleXMLElement($str);
if($x->subnode->children())
print 'yes';
else
print 'no';
---------
will print 'no';
If the
$str='<rootnode><subnode><newnode></newnode></subnode></rootnode>';
it will print yes.
But the same will happen if the subnode has an attribute like:
$str = '<rootnode><subnode id="2"></subnode></rootnode>';
But if we use foreach($x->subnode->children() as $key=>$value)
in the latter example we will not get anything.
I think is wrong the children() method to return object when there are no
child objects and the node has attributes.
The workaround I use is to extend the SimpleXMLElement
--------
class SimpleXMLElement2 extends SimpleXMLElement
{
public function has_children()
{
foreach($this->children() as $node)
return true;
return false;
}
}
------
And then we can check with if($x->subnode->has_children())
Issue #2:
Xpath on nodes.
Let we have the example:
-----------------
$str =
'<rootnode><level1_node1><level2_node1></level2_node1></level1_node1><level1_node2></level1_node2></rootnode>';
$x = new SimpleXMLElement($str);
$r1 = $x->xpath('/*');
print $r1[0]->getName();//prints rootnode
$r2 = $x->level1_node1[0]->xpath('/*');
print $r2[0]->getName();//prints rootnode
$z = clone $x->level1_node1[0];
$r3 = $z->xpath('/*');
print $r3[0]->getName();//prints rootnode
//print $z->getName();//ok
------------------
I personally think that the xpath must be evaluated against the node which
method is called, not always against the rootnode.
So in the second example I would expect it to return level1_node1, and
especially in the thirds example.
Even in the third example the xpath is evaluated against the original XML
structure, not the subnode (level1_node1).
I think this is incorrect and leads to a confusion - for example we can pass
a node to a function like:
--------
function do_something($node)
{
//print $node->getName();//prints correct - the name of the supplied
node - level1_node1
$r1 = $node->xpath('/*');
print $r1[0]->getName();
}
do_something(clone $x->level1_node1[0]);
--------
The do_something function is not aware at all about the full xml structure
and one could think that the expression will be evaluated just against the
supplied node, but it is not that the case.
And I do not have a workaround for that for the moment.
Any comments, solutions, and opinions about that SimpleXML functionality are
welcome.

Depending on your needs and the license etc. you could take a look at
phpadsnew or (after quick google) OpenAds as it is now called:
http://www.openads.org/
Perhaps customising that code will save you some time?

Subject: [PHP] Adserver programming with php
Hi there,
I am thinking about creating a kind of adserver which is customized for my
needs. As I would be most confident in doing this with php, I am asking
myself if this is the right choice or if it would be wiser to take a C++
aproach for example to get a higher performance just in case the site grows
fast.
Do you guys think that a php build webserver would be able to scale and
perform well enough for serving millions of adimpressions daily?
Thank you for any advice,
Merlin

are volcan exams really harder than actual php5 exam as phparch asserted?

Actually I found the real exam harder than the test exam. It may have just
been the question set I ended up with, but it was a lot more nitpicky on
details that I rarely use in my work.

probably permissions is the problem - i.e. IIS doesn't have the right to run a
shell and/or the binary in question.
BUT who cares ... you shouldn't be using exec() in a script that's evoked via a
webserver if you can really help it.
it seems you have a binary that takes a url and makes a visual snapshot of the
resulting webpage as seen in IE, I
would suggest that you run a background task that regularly updates a cache of
such images using the exec() technique
given above (maybe using a database as a source of urls to check) and then have
you web scripts use the cached data
as needed.
otherwise your off into the dark woods of windows/IIS permissions (can't help
you there I'm afraid)

While I'm sure this is a stupid question and the solution will be
obvious to everyone here, this is confusing me.
I'm trying to control a device over a serial port using a PHP script,
and one of the things I need to do is read a 26-byte string from an
EEPROM, using a command that returns two bytes at a time, and write
similar strings using a similar command. For example, to read the first
two bytes of one such string beginning at address 0x484, I would send:
04 84 00 00 BB
Here's the code I've written so far:
$string = 1; //which of 200 strings I want to read
$base = pack("H*",dechex((($string-1)*hexdec(0x1a))+hexdec(0x484)));
//calculate the base address of the string (the first starts at 0x484)
for($i=0;$i < 13;$i++) { //iterate 13 times (26 bytes / 2 bytes at a time)
dio_write($serial,$base."\x00\x00\xbb",5); //send the command
$output[] = dio_read($serial,1); // read first byte
$output[] = dio_read($serial,1); // read second byte
$base = pack("H*",dechex(hexdec(bin2hex($base))+2)); //increment address
}
There are two things wrong with this. First, the final line isn't doing
what it's supposed to. Instead of adding 2 to the value of $base each
time, It's producing a pattern like this:
0x484, 0x486, 0x73, 0x73, 0x73, 0x488, 0x48a, 0x48c, 0x48e, 0x490, 0x74,
0x74, 0x74
Second, the format of $base doesn't seem to be handled correctly in line
4 of the above code. Given a value of 0x484, this line should write the
bytes "04 84", but it is obviously not doing so, given the response I
get from the device (it sends "FF FF" instead of the expected value at
that address, which I get when I remove the variable and manually
specify the address).
What are the solutions to these problems?
Thanks,
-Joe Veldhuis
