Example of POST vpz/input in PHP language

For the simulator ‘wwdm.vpz’ whose Id is 266, use the PHP code into a php tag :

<?php

… PHP code …

?>

Example illustrating :

• modifying begin,

• modifying duration,

• modifying some parameters with ‘pars’,

• value ‘all’ as ‘parselect’,

• ‘tree’ as style of presentation,

• ‘json’ as format,

• with ‘application/json’ as ‘Content-Type’

  Memo

  # PHP code :
  
  # send POST request and return response datas
  function send_post_and_receive($url, $inputdata) {
      #
      ob_start();
      $c = curl_init();
      #
      curl_setopt($c, CURLOPT_POST, TRUE);
      curl_setopt($c, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
      #
      curl_setopt($c, CURLOPT_URL, $url);
      #
      # to follow redirect
      curl_setopt($c, CURLOPT_FOLLOWLOCATION, True);
      #
      $json_inputdata = json_encode($inputdata);
      curl_setopt($c, CURLOPT_POSTFIELDS, $json_inputdata);
      #
      curl_exec($c);
      $buffer_str = ob_get_contents();
      ob_end_clean();
      #
      $responsedata = json_decode($buffer_str, TRUE);
      curl_close($c);
