I am trying to open a blocking stream using fsockopen. I want to write and read
XML input/output from a server. After opening the steam I will send a XML
request to server using the stream. Once this request is sent, I want to keep
listening on the port indefinitely.
I tried using blocking stream for this with a huge timeout. But had no success
as it was not waiting for such a long period.
Code:
$parser = xml_parser_create("UTF-8");
if($stream = @fsockopen($host, $port, $errorno, $errorstr, $timeout)) {
stream_set_blocking($stream, 1);
stream_set_timeout($stream, TIMEOUT);
fwrite($stream, $xml."\n");
sleep(2);
while (!feof($stream)) {
$data = fread($stream, 1024);
xml_parse($parser, $data, feof($stream));
}
}
$xml has the xml to be sent. TIMEOUT is set to 3600*24 and $timeout is set to
300. As it is a blocking stream, till the data is not arrived, feof should not
happen. But in this case, the stream is not waiting and returning eof. What is
the problem with this code?
I tried using even stream_select but faced same issue.

Hi Shawn
Thanks for answering my query. I have looked at the suggestions:
$xml = simplexml_load_file('file.xml', 'SimpleXMLElement', LIBXML_NOCDATA);
I am/was able to load the file OK and to access the data by iteration.
However, I can't find a way to extract data by attributes. I need something
like $string=<element idtype="11" lang="fr" label="Description - Etage">.
Obviously, that won't work but that's the result I need. How do I get the
data out of one of these elements by specifying its idtype and lang? I've
google for hours on this and for another hour on SimpleXMLElement.

Hi Terry,
look at the PHP.NET documentation. There indicates the use of
simpleXMLElement structures. If you want to extract elements from this
object, please read there how this work. By the way, it would be
interesting to see, how your XML is made. May be is usefull to use
another class like DOM.
regards
carlos
