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 by ‘cname.pname’,

• ‘compactlist’ as style of presentation,

• ‘json’ as format,

• values of type cname.pname as ‘parselect’ :

  value ‘cond_wwdm.A’ to select the parameter named ‘A’ of the condition named ‘cond_wwdm’.

  value ‘cond_wwdm.B’ to select the parameter named ‘B’ of the condition named ‘cond_wwdm’.

  value ‘cond_wwdm.Eb’ to select the parameter named ‘Eb’ of the condition named ‘cond_wwdm’.

  value ‘cond_wwdm.TI’ to select the parameter named ‘TI’ of the condition named ‘cond_wwdm’.

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

  # PHP code :
  
  # send POST request and return response datas
