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 with ‘pars’,

• ‘tree’ 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 ‘all’ as ‘outselect’,

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