Display Curl Response Sequential one by one - php

I have simple POST CURL request script,
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
curl_setopt($ch, CURLOPT_POST, 1);
$result = curl_exec($ch);
The problem i am facing is, if i fetch post data from db or i fetch post data from a form, when i process data in large quantity, for example 60 times. The curl displays the output until and unless all 60 requests are completed.
I want the curl to display output one by one not all at once when the query is completed e.g.
Echo 1st Response
Echo 2nd Response
Echo 3rd Response


What you are requesting appears to be undefined.
PHP, and any other HTTP Server can only start sending data, when the data-length is know. When echoing, your server is supposed to assemble the reply, then organize a transfer.
If you want to assemble a document, that can be done, use AJAX, or any other request/reply system to assemble divs/fields each.
An example would be:
"Base document" -> [N] divs or fields. Each field requests its related procesing.
When basereceives data, it assembles in its related div.

Uploading an XML file using cURL

I am uploading an xml file to a supplier url. Not the content as a post, but the file itself. Regarding the response from the server, the instructions read as follows.
"For each OrderRequest from a client, the server will reply with a single OrderRequestResponse."
And:
"Once a successful order request is received, it will be placed in the queue to be run. The client shall not wait for this report to be generated – the communication over the HTTP socket will only consist of two messages – an OrderRequest, and an OrderRequestResponse."
It then goes on to say that the response may happen anywhere between 1 and 5 minutes later.
So the question is this - I would like to see the respose and make sure that the order has been accepted correctly, but how do i code for this given that i can't leave my cURL routine open for 5 minutes waiting. Can i tell the cURL request where to send the response within the parameters and then close the curl session and have my location process the response to email me or act on the content of the response.
Here is my upload code so far:
$xml = curl_file_create($thefile);
$data = array('test_file' => $xml);
$url = "www.supplierlocation.co.uk/etc";
$curlSession = curl_init();
curl_setopt ($curlSession, CURLOPT_URL, $url);
curl_setopt ($curlSession, CURLOPT_POST, 1);
curl_setopt ($curlSession, CURLOPT_POSTFIELDS, $data);
$ch_result = curl_exec($curlSession);
curl_close($curlSession);
What, if anything can i add so that the respose ends up somewhere that i can deal with it even after the session is closed.
[Does anybody know where i can find example of php code to respond to the response post my side. It would be an XML file that is received.]
Thanks,

Complicated: 4 consecutive curls with XML in between

I've a tricky question on how to deal with consecutive curls in PHP. I have this incredibile data flow:
example.com/one.php post data via curl to another.com/two.php
another.com/two.php post data via curl to another.com/three.php
another.com/three.php responds me with XML (or JSON) back to another.com/two.php
another.php/two.php transforms the XML into a php array and then into a query string that i post via curl back to the origin example.com/one.php
It works. If you are wondering why i have this insane data flow it's due to the fact that another.com/three.php is an obfuscated file with Ioncube. I can't edit it but i have to add some checks before i can send data to him. Don't waste time trying to figure out how i can make it in an alternative way because there isn't one (trust me).
On example.com/one.php there's a form where users fill in data. When they press "Submit" they remain on this page while "silently" i make 1->2->3->4 to get their response (the $_POST of step 4) then can save it into example.com/log.txt. Again it works.
Now my question is: how can i display the $_POST response (which is the same i get in log.txt file) in example.com/one.php? I mean this is what i have in step 4.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, example.com/one.php);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$xml = curl_exec($ch);
$_POST arrives on example.com/one.php but of course users and this curl are on two different level. I tryed playing with file_get_contents(), sleep() and CURLOPT_RETURNTRANSFER with no success. What's the answer this this question? I would go for sessions or ob_start() but i'm not sure of it.

cURL returning XML or JSON

I've got a form say here - http://example.com/palreg.php
Once people register I'll be sending them an email with the link that will allow them to edit their details (I know it's a crazy way of doing things, but I am working on someone else's code so don't mind) for instance the url as such http://example.com/palreg.php?paliD=1234, and when they go to that page the form will be populated with their information so that they can make changes.
Now the problem is that the DB is in a different site and the information has to be passed to that site to perform a select action, to do so I use cURL to send the information like so
$url = "http://example2.com/processXML.php";
$xmlStr will be like this
<table>tab_name</table>
<action>select</action>
<palid>1234</palid>
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, 'xmlstr='.$xmlStr);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
On the other end (http://example2.com/processXML.php) I convert the xml to an array and perform the query to select pal information based on the id sent.
The real question now is how do I send the retrieved pal information (as xml or json or array) back so that i can populate the form with the returned data.
Also can I do a return $dataArray; in processXML.php and be able to grab it?
OK to make things a bit clearer, what I do in processXML.php is
retrieve the result set and do this
print json_encode($resultArray);
not should I print or return
Thank you, and do let me know if things aren't clear.

just encode it as you want, and echo it to the page. your $data= will contain the echoed contents. Personal preference has been to use JSON since it's so easy to throw around. as in
//Bunch of DB stuff..
$row=mysql_fetch_however_you_handle_it();
echo json_encode($row);
//on your receiving end, that just did the cURL send,
$row=json_decode($data,true);//decode the JSON straight into an array...

When you pull the information from the database and process it in processXML.php, add the results to an array, use json_encode() to convert the array to JSON, and then echo the results to the page.

Just echo out the data you need to send back to the form, in your format of choice, and fetch that response in thepalreg.php.

php to translate GET request to POST request

i have a hosted script somewhere that only accept POST request.
example, some.hosted/script.php
how can i setup another simple php that can accept GET request and then POST it to the hosted script.
so that i can put up a link like this: other.site/post2hostedscript.php?postthis=data
and then it POST postthis=data to the hosted script.
tnx
edit:
post2hostedscript.php do not give any result.
the result will go directly to some.hosted/script.php
just as if the user POST directly at the hosted script.

Your post2hostedscript.php will have to :
Fetch all parameters received as GET
Construct a POST query
Send it
And, probably, return the result of that POST request.
This can probably be done using curl, for instance ; something like this should get you started :
$queryString = $_SERVER['QUERY_STRING'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.othersite.com/post2hostedscript.php");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $queryString);
curl_exec($ch);
curl_close($ch);
For a list of options that can be used with curl, you can take a look at the page of curl_setopt.
Here, you'll have to use, at least :
CURLOPT_POST : as you want to send a POST request, and not a GET
CURLOPT_RETURNTRANSFER : depending on whether you want curl_exec to return the result of the request, or to just output it.
CURLOPT_POSTFIELDS : The data that will be posted -- i.e. what you have in the query string of your incoming request.
And note that the response from the POST request might include some interesting HTTP header -- if needed, you'll have to fetch them (see the CURLOPT_HEADER option), and re-send the interesting ones in your own response (see the header function).

Take a look at the "curl" functions, they provide everything you need.

You might consider replacing all instances of $_POST in the old script to $_REQUEST, which will result in it accepting both GET and POST alike.

Retrieving web content multiple times simultaneously in php

I use curl to retrieve web content from another site but there is two problems;
first, it takes an average 4 sec period to retrieve the contents and I don't know if there is any way to reduce it; second, some times remote server returns a short error message instead of full content.
I was thinking it would very efficient to send 3 request simultaneously, then check the first received response to see if it's an error or not and check the second respond if the first one was an error. by this method it would not be need to wait a full 4 secs to get retry response if the first one was error. but I don't know if it's possible to doing it.
It would be very appreciated if any one write a simple code to send multiple request simultaneously.
Here is my initial code:
<?php
$then = microtime(true);
