Question

I want to build a json object with PHP.
The json object needs to be like this (for creating a google line charts):

{"cols":[{"id":"bingo","label":"bingo","type":"string"},{"id":"value","label":"value","type":"number"}],"rows":[{"c":[{"v":"date1"},{"v":151}]},{"c":[{"v":"date2"},{"v":102}]},{"c":[{"v":"date3"},{"v":52}]},{"c":[{"v":"date4"},{"v":32}]},{"c":[{"v":"date5"},{"v":7}]},{"c":[{"v":"date5"},{"v":7}]},{"c":[{"v":"date5"},{"v":7}]}]}

I have a problem creating the following part:

{"c":[{"v":"date3"},{"v":52}]},{"c":[{"v":"date4"},{"v":32}]},{"c":[{"v":"date5"},{"v":7}]},{"c":[{"v":"date5"},{"v":7}]},{"c":[{"v":"date5"},{"v":7}]}

How can I create this with PHP?

PHP comes with a JSON extension. The only thing you will need to figure out is how you have to create the data in PHP. [] in JSON is an array, {} is a dictionary. For the part mentioned you’ll need something like this:

$foo = array(
   array(
      'c' => array(
         array('v' => 'date3'),
         array('v' => 52)
      )
   ),
   array(
      'c' => array(
         array('v' => 'date4'),
         array('v' => 32)
      )
   ),
   // and so on...
);
