PHP - Setting Response Headers Based On Curl Response

Folks,

I have a mysql tbl called "links".

In it a column named "keywords".

The row 0 has a keyword "search" in the "keywords" column.

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. So it should work and respond!

	<form name = "search" method = "POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<label for="keywords">Keywords:*</label>
<input type="text" name="keywords" id="keywords" placeholder="Input Keywords" required>
<br>
<input type="button" name="search_links" id="search_links" value="Search Links!">
<br>
<input type="reset">
<br>
</form>
	

Full short code ...

	<?php
//include('error_reporting.php');
ini_set('error_reporting','E_ALL');//Same as: error_reporting(E_ALL);
ini_set('display_errors','1');
ini_set('display_startup_errors','1');
?>
	<form name = "search" method = "POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<label for="keywords">Keywords:*</label>
<input type="text" name="keywords" id="keywords" placeholder="Input Keywords" required>
<br>
<input type="button" name="search_links" id="search_links" value="Search Links!">
<br>
<input type="reset">
<br>
</form>

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)

        //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?

Hi Guys,

I have this SOAP message to be parsed using SimpleXML:

<soap:envelope 
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
               xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:body>
    <isokresponse xmlns="http://tempuri.org/">
      <isokresult>1</isokresult>
    </isokresponse>
  </soap:body>
</soap:envelope>

Then I load the XML:

$xml = simplexml_load_string($result);

I assume I need to register namespace e.g.

$xml->registerXPathNamespace("soap","http://schemas.xmlsoap.org/soap/envelope/");

But what's next? How do I get the value of the element isokresult?

Thank you so much

$json_object = json_decode($unparsed_json, true);

array(1) {
  ["google.com"]=>
  array(2) {
    ["status"]=>
    string(16) "regthroughothers"
    ["classkey"]=>
    string(6) "domcno"
  }
}

echo $json_object->['status'];
