new Date into Array php - php

Question

For Google Visualization I coded the JSON by hand (Messy I know) I did not think about ''s in NAME_TEAM which has recently come about an issue as my first team name was entered with an apostrophe. I have read this post and tried to implement php json_encode. I am having an issue with the dates. The new Date works fine in the old messy json format, however I get an error Fatal error: Class 'Date' when I try use anything similar for the Json_encode version. The format must be date for the visualization api to understand the values.
foreach ($data as $row) {
$dateArray = explode('-', $row['THE_DATE']);
$year = $dateArray[0];
$month = $dateArray[1] - 1;
$day = $dateArray[2];
$dataArray[] = "[new Date ($year, $month, $day), {$row['ORANGE']}, {$row['GREEN']}, '{$row['NAME_TEAM']}']";
$itemOutput[] = array(
new Date($year, $month, $day),
$row['ORANGE_SCORE'],
$row['GREEN_SCORE'],
$row['NAME_TEAM'],
);
}
echo "data.addRows(" . json_encode($itemOutput) . ");" ;
Data Table creation
function drawDashboard() {
//var data = new google.visualization.DataTable();
var data = new google.visualization.DataTable(<?php echo json_encode($itemOutput, JSON_NUMERIC_CHECK); ?>);
data.addColumn('date', 'Date');
data.addColumn('number', 'ORANGE_SCORE');
data.addColumn('number', 'GREEN_SCORE');
data.addColumn('string', 'NAME_TEAM');
// data.addRows(<?php echo '[' . implode(',', $dataArray) . ']'; ?>);
ARRAY FORMAT
{"c":[
{"Date":"new Date(2013, 9, 19)"},
{"ORANGE_SCORE":14},
{"GREEN_SCORE":7},
{"NAME_TEAM":"Trigon"}]
},

You can't use Date objects in JSON; the only way to transmit dates is via strings, but the DataTable.addRows method does not parse strings into Date objects, so you will have to convert to the full JSON structure to make this work. Here's an example:
$itemOutput = array(
'cols' => array(
array('type' => 'date', 'label' => 'Date'),
array('type' => 'number', 'label' => 'ORANGE_SCORE'),
array('type' => 'number', 'label' => 'GREEN_SCORE'),
array('type' => 'string', 'label' => 'NAME_TEAM')
),
'rows' => array()
);
foreach ($data as $row) {
$dateArray = explode('-', $row['THE_DATE']);
$year = $dateArray[0];
$month = $dateArray[1] - 1;
$day = $dateArray[2];
$itemOutput['rows'][] = array('c' => array(
array('v' => "Date($year, $month, $day)"),
array('v' => $row['ORANGE_SCORE']),
array('v' => $row['GREEN_SCORE']),
array('v' => $row['NAME_TEAM'])
));
}
Then in javascript:
var data = new google.visualization.DataTable(<?php echo json_encode($itemOutput, JSON_NUMERIC_CHECK); ?>);

If case 1 or 2, What do you want?
result is Case 2.
