Example of POST vpz/output 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’,

• ‘compact’ as style of presentation,

• ‘json’ as format,

• value ‘single’ as plan, or value ‘linear’ in case of multiple simulation

• value ‘dataframe’ as restype (or ‘matrix’)

• value of type vname.oname as ‘outselect’ :

  value ‘view.top:wwdm.LAI’ to select the ‘LAI’ output data of the view named ‘view’.

  value ‘view.top:wwdm.ST’ to select the ‘ST’ output data of the view named ‘view’.

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