[PHP] PHP timeout doing fread from Apache Coyote
I am trying to communicate with an API of a vendors of ours. They provide a
Perl example that works fast and well. I am trying to do the same thing with
a PHP class. The response takes over a minute before the response comes
back. I see from the response text that the API is running on Apache
Coyote/1.0. Does anyone know of issues with this match-up, here is the
snippet of code that seems to be hanging. Using my Komodo debugger, it
points to the line with 'while($data=fread($fp, 32768))' while waiting for
execution to continue. Using a Perl script provided by them, I get a
response in seconds. Basically, my PHP page prepares content and variables
and then uses this class to send XML formatted content to receive a
response.
...
$fp=fsockopen($this-server, $this-port, $this-errno,
$this-errstr, $this-timeout);
if(!$fp) {
$this-errstr=Cant Connect to Service ($this-server:$this-port,
$this-errno, $this-errstr);
return;
}
if (!fputs($fp, $op, strlen($op))) {
$this-errstr=Write error;
return;
} else {
$ipd = ;
while($data=fread($fp, 32768)) {
$ipd.=$data;
}
$this-responsetext = $ipd;
//echo p.$ipd./p;
$ipd = $this-_parse_header($ipd);
}
fclose($fp);
return $ipd;

which HTTP version are you requesting? I know that if you send a
HTTP/1.1 then a lot of servers send the data in chunks, thus your
retrieval code needs to be different. If it is HTTP/1.1 try using
HTTP/1.0 instead.
$this-errstr=Write error;
return;
} else {
$ipd = ;
while($data=fread($fp, 32768)) {
Have you tried smaller requests mabey 512? although that shouldn't
matter, but you might be able to see if it is getting data back at
all.
$ipd.=$data;
}
HTH,

Same difference with the 1.0, I was using 1.1, here is the complete request
and response. The response comes back as 1.1 regardless of what I use (of
course, the xml parameter is urlencoded):
Request:

Yes, I've tried 128 and get the same delay.
Thanks for any help:)
