PHP - Should The Request Hold The Response, The Response Hold The Request, Or Both (or Neither)??
I have an application which receives multiple requests at once and it advantageous to process them as a group. I am thinking I should be doing something like the following, however, as I just came up with it on my own, would appreciate a critique. Is this a common design pattern or should I be doing something differently? Note that I have three questions asking specific questions in the below code (look for the comments with question marks).
Thanks
<?php
class Request
{
private $response, $data;
public function __construct(array $data)
{
$this->data=$data;
return $this->response=new Response($this);
}
public function getResponse():Response
{
return $this->response;
}
public function updateResponse($results):self
{
$this->response->setResults($results);
return $this;
}
}
<?php
class Response
{
private $request, $results;
public function __construct(Request $request)
{
//I don't really see the need for this. Any need?
$this->request=$request;
}
public function setResults($results):self
{
$this->results=$results;
return $this;
}
public function getResults()
{
return $this->results;
}
}
<?php
class Container implements \Iterator
{
private $position = 0;
private $requests, $response;
public function __construct(WorkerObject $worker, array $inputArray)
{
$this->requests=[];
$this->responses=[];
foreach($inputArray as $i =>$inputData) {
$this->requests[$i]=new Request($inputData);
$this->responses[]=$this->responses[$i]->getResponse();
}
//Should WorkerObject be responsible to execute Request::updateResponse() method?
$worker->process_requests(...$this->requests);
//Or should I iterate over my requests upon completion and execute updateResponse() method?
}
public function __construct() {
$this->position = 0;
}
public function rewind() {
$this->position = 0;
}
public function current() {
return $this->responses[$this->position];
}
public function key() {
//Will this work?
return $this->requests[$this->position];
}
public function next() {
++$this->position;
}
public function valid() {
return isset($this->responses[$this->position]);
}
}
<?php
//...
$container=new Container(new WorkerObject, $inputArray);
foreach($container as $request => $response) {
//...
}
Similar TutorialsHello, I am trying to do multiple curl requests and get the response for each one output to the screen. I have wrote the following code, but only appear to be getting the last response when outputting $result. What am i doing wrong? Is there a way to wait for each curl request to be completed before appending to $result so I can see them all? Thanks very much if (isset($_POST['submit'])) {
$result = array();
foreach ($textAr as $line) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
$result[] = curl_exec ($ch);
}
curl_close ($ch);
echo "<pre>";
print_r($result);
echo "</pre>";
}
I need to make my client's site distinguish among different tabs in the same browser. (See http://www.phpfreaks.com/forums/index.php?topic=357772.0 for background.) I create a tab ID when the user first visits the site in a particular tab, and I'm passing it from page to page as a parameter. This seems to be the only way to do what I need. The tab ID is always passed through POST so that the user won't see it. If it were visible, users could make trouble (or more likely get in trouble) by adding or removing the ID themselves. This is not simple where a page is loaded by a hyperlink. The anchor tag passes parameters via GET, period. The solution I found is to link to a script named post.php, which takes the real link target and the tab ID as parameters, sends the browser a form that passes the tab ID to the real link target via POST, and auto-submits the form via JavaScript. This works, but it requires two round trips to the browser to load a page. It's also a pain to code. Is there a more efficient way to do this... perhaps a way to make the server send the browser a POST response, even though it made a GET request? If it matters, the server is Apache 2.x. You would think the answer would be all over the Internet and easy to find, but it’s not. I have searched many times, and in all the multitude of search results I have still never found an adequate usable answer. The MOST you ever find is someone saying how easy it is with PHP, but they don’t tell you how, even when the person they are answering asks them (odd). You can be that one in a billion person who finally answers it for real and helps someone out. I have a simple HTML form with data fields first_name, last_name, email, phone, country, a few hidden inputs, and a single submit button, like so: (Please note: the method is GET, not Post.) <form action="https://MyDomainOnMyServer.com/MyPHPScript.php”> <input type="text" name="first_name" value="" /> <input type="text" name="last_name" value="" /> <input type="text" name="email" value="" /> <input type="text" name="phone" value="" /> <input type="hidden" name="type" value="type123"> <input type="hidden" name="project" value="new123"> <select required name="country"> <option value="">Choose your country</option> <option value="US">United States</option> <option value="CA">Canada</option> <option value="GB">United Kingdom</option> <option value="Many More">Many More Countries</option> </select> <input type="submit" value="Submit Form" /> </form> NOTE: Originally, the form action would have been: action="https://TheirExampleDomainOnTheirRemoteServer.com/TheirRemotePHPScript.php" name="form1234" Upon clicking the single submit button only, what I need to have happen is this: 1. Send me an email to whatever@whatever.tld containing all the form submission data 2. Place the form submission data into a MySQL database having the corresponding data fields 3. Send the form submission contents including the hidden input values to "https://TheirExampleDomainOnTheirRemoteServer.com/TheirRemotePHPScript.php" name="form1234" AS IF that had remained set as the original form action to begin with So basically what I’m trying to obtain is the cleanest possible PHP script that will do those three things, which is essentially what others have asked for over the years in search results I have found, but no one has ever provided it in a clear instance that works. If I can just see such a script, I should be able to see how it works and then do what I need. Thanks. Reply A HTTP request is made to the server, Slim creates a Request and Response object, content in the Request is sent to another server using cURL via Guzzle, Guzzle returns its own Response, and content from Guzzle's response must be returned by the original Slim response. Would you recommend white-listing or black-listing response headers, and which specific headers? Similarly, would you recommend white-listing or black-listing the request headers sent via cURL, and which specific headers? Thanks

Doing something wrong, but don't see it. How should one retrieve a POST parameter? My $request->toArray()['html'] works, but I am sure it is not the "right way".

Hit Checkout button the following happens.. Code: [Select] $conn = db_connect(); // we want to insert the order as a transaction // start one by turning off autocommit $conn->autocommit(FALSE); Then order, order_items and customers tables are updated If I then include this code after the order is on the database it commits fine Code: [Select] // end transaction $conn->commit(); $conn->autocommit(TRUE); However I think i have a huge sequence error in that it is only at this point I ask them for the payment card details! If the payment fails I've still commited. I tried moving the $conn->commit(); to the end of the card processing but it just stops at that command I guess because when I went back to solicit the card payment details the plot got lost. I hope this is making sense... Is it possible to keep the transaction / unit of work pending i.e not committed until the result of the next dialog and only commit on a successful card payment else backout? The problem is I can't go to the card payment until I know the entire order process worked.

I am doing a search for the words "search" in the html form. Clicking the button gives no response! What is wrong ? I get no mysql connection error. Nor any php error.

Hello All, running into a situation that I have not seen before. I have been seeing in multiple areas of my application that the response received from the server has 2 JSON responses in it. Here is a sample function: private function getCatalogItems(){ $start = ($_REQUEST["start"] == null)? 0 : $_REQUEST["start"]; $count = ($_REQUEST["limit"] == null)? 20 : $_REQUEST["limit"]; $q = "SELECT c.`id`, c.`catalog_number`, c.`long_description`, CONCAT(c.`catalog_number`, ' - ', c.`long_description`) AS `display` FROM catalog c"; if(!empty($_REQUEST['query'])){ $q .= " WHERE c.`catalog_number` LIKE '%".$_POST['query']."%'"; } $q .= " ORDER BY c.`catalog_number` ASC LIMIT ".$start.",".$count; $rs = $this->db->get_results($q); $total = $this->db->num_rows; $buff = '{"total":"'.$total.'","data":'.json_encode($rs).'}'; $this->c->returnJSON($buff); } The "returnJSON" function looks like this. public function returnJSON($json){ $contentType = "application/json; charset=utf-8"; header("Content-Type: {$contentType}"); header("Content-Size: " . strlen($json)); echo $json; } As you can see this simply sets the headers of the response. It has been a real head scratcher. Anyone come across something like this before? How can I receive a response from the server with JSON data, when the function that retrieves the data and returns it to the browser has been completely commented out? I am making an AJAX request for JSON formatted data and for some reason it returns a response when it shouldn't as there is no function? Hello, I'm trying to get webservice response in xml format. I'm getting the response but it's not in xml. It's just text. Can someone please look at the code ? <?php $targeturl="https://api.com"; $DevKey= "xxxxx"; // return xml feed $ch = curl_init($targeturl); curl_setopt($ch, CURLOPT_POST, FAlSE); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: '.$DevKey)); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $response = curl_exec($ch); $xml = new SimpleXMLElement($response); curl_close($ch); echo $response; // will print in browser all country codes in an xml format /* ADD YOUR OWN CODE HERE TO DO WHAT YOU WANT WITH THE RESPONSE. MAYBE SAVE RESULTS TO A FILE OR THE PARSE THE RESULTS INTO A DATABASE? */ ?> HI, I need to know how to get the response objects from a webserve call. I call the following webservice: $params = array('mobiUser'=>"WJBASSON",'mobiPass'=>"83dop"); $soap = new SoapClient('http://172.18.22.182/csp/ampath/ReportGeneration.Mobi.Services.cls?WSDL'); $result = $soap->login($params); When I do var_dump($result) I receive the following: stdClass Object ( [loginResult] => stdClass Object ( [MobiRegUserID] => 34 [MobiRegUserName] => WJBasson ) ) I need to know how can I get the values of objects MobiRegUserID and MobiRegUserName ?? Hi, I submit form data as an xml string - $strXML - using curl: curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, '1'); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, array('lead'=>$strXML)); $strResult = curl_exec($ch); // close cURL resource, and free up system resources curl_close($ch); The xml response is: <result> <posting_error>0</posting_error> <lead>0</lead> <valid>1</valid> <redirect_url>http://www.xxx.com</redirect_url> </result> and I need to redirect the user to <redirect_url>. I am trying the following: $xml = new SimpleXMLElement($strResult); header("Location:" . $xml->result->redirect_url); but with no joy. Could anyone suggest how I can achieve what I want? Thanks. Hello, I am needing to cache a json response from an API so I am not making requests on each load. I have come across some code that is suppose to accomplish this but, it seems to not be working and can't figure out as to why. I created the cache file with 777 but it doesn't write or read from that file when I echo out the results.
The code below is just what is suppose to get the contents and cache it. At the end I tried to print it so I can test it to see it prints the response from the cache file but, nothing and the cache file does exists.
This is the first time I have tried something like this so please be gentle.
// cachePath is name of the path and file used to store cached current conditions gathered from the API request

Edited by Texan78, 20 December 2014 - 03:51 PM. I have been using PHP CURL to obtain stock data... The URL is
https://trade.plus50...ntName=Facebook
Essentially, it is supposed to return date, time, and price of stock tick data
But it returns stuff like "HrCy/h6wsw4esLL+HrCzDh6wsw4esLMOHrCzDh6wsu4esLLeHrCy7h6wsu4esLL"
So... I would like to know, what is this format, and how do I decode it? Thanks
Here is the full response....

Hi
I'm having this issue, when i put an url who must show me records i have blank html page
<?php
error_reporting(E_ALL | E_NOTICE);
ini_set('display_errors', '1');
require_once 'database_connection.php';
$post=array(

'orden'=>(isset($_REQUEST['sord']))?$_REQUEST['sord']:'',
'search'=>(isset($_REQUEST['_search']))?$_REQUEST['_search']:'',
);
$se ="";
if($post['search'] == 'true'){
$b = array();
$search['like']=elements(array('utilizador','email'),$_REQUEST);
foreach($search['like'] as $key => $value){
if($value != false) $b[]="$key like '%$value%'";
}
$search['where']=elements(array('nome','utilizador','email'),$_REQUEST);
foreach($search['where'] as $key => $value){
if($value != false) $b[]="$key = '$value'";
}
$se=" where ".implode(' and ',$b );
}
$query = mysql_query("select count(*) as t from utilizador".$se);
if(!$query)
echo mysql_error();
$count = mysql_result($query,0);
if( $count > 0 && $post['limit'] > 0) {
$total_pages = ceil($count/$post['limit']);
if ($post['page'] > $total_pages) $post['page']=$total_pages;
$post['offset']=$post['limit']*$post['page'] - $post['limit'];
} else {
$total_pages = 0;
$post['page']=0;
$post['offset']=0;
}
$sql = "SELECT idutilizador, nome, utilizador, telefone, email, password FROM utilizador ".$se;
if( !empty($post['orden']) && !empty($post['orderby']))
$sql .= " ORDER BY $post[orderby] $post[orden] ";
if($post['limit'] && $post['offset']) $sql.=" limit $post[offset], $post[limit]";
elseif($post['limit']) $sql .=" limit 0,$post[limit]";
$query = mysql_query($sql);
if(!$query)
echo mysql_error();
$result = array();
$i = 0;
while($row = mysql_fetch_object($query)){
$result[$i]['id']=$row->idutilizador;
$result[$i]['cell']=array($row->idutilizador,$row->nome,$row->utilizador,$row->telefone,$row->email,$row->password);
$i++;
}
$json = new stdClass();
$json->rows=$result;
$json->total=$total_pages;
$json->page=$post['page'];
$json->records=$count;
echo json_encode($json);
function elements($items, $array, $default = FALSE)
{
$return = array();
if ( ! is_array($items)){
$items = array($items);
}
foreach ($items as $item){
if (isset($array[$item])){
$return[$item] = $array[$item];
}else{
$return[$item] = $default;
}
}
return $return;
}
?>
*Update
It works if i put
$result[$i]['cell']=array($row->idutilizador,$row->telefone,$row->email,$row->password);So i'm think it's because in $nome(ex: Luis Miguel) and $utlizador(ex Susana Maria) don't accept this (space between words) it is correct? Edited by alphasil, 19 January 2015 - 08:54 AM. |
