Question

Is it possible to do in one line calling a method that returns an array() and directly get a value of this array ?

For example, instead of :

$response = $var->getResponse()->getResponseInfo();
$http_code = $response['http_code'];
echo $http_code;

Do something like this :

echo $var->getResponse()->getResponseInfo()['http_code'];

This example does not work, I get a syntax error.

What you can do is to pass the directly to your function. Your function should be such that if a variable name is passed to it, it should the value of that variable, else an array with all variables values.

You can do it as:

<?php
// pass your variable to the function getResponseInfo, for which you want the value. 
echo $var->getResponse()->getResponseInfo('http_code');
?>

Your function:

<?php
// by default, it returns an array of all variables. If a variable name is passed, it returns just that value.
function getResponseInfo( $var=null ) {
   // create your array as usual. let's assume it's $result
   /*
       $result = array( 'http_code'=>200,'http_status'=>'ok','content_length'=>1589 );
   */

   if( isset( $var ) && array_key_exists( $var, $result ) ) {
      return $result[ $var ];
   } else {
      return $result;
   }
}
?>

Hope it helps.
