This little php program:
<?php
$arr = array('abc'=>1, 'def'=>array('marketing_campaign_id', 'status',
'status'), 'ghi'=>array('eg', 'eq', 'eq'));
$json = json_encode($arr);
print '<pre>'; print_r($arr);print'</pre>';
print 'json endoded = '.$json;
?>
generates this output:
Array
(
[abc] => 1
[def] => Array
(
[0] => marketing_campaign_id
[1] => status
[2] => status
)
[ghi] => Array
(
[0] => eg
[1] => eq
[2] => eq
)
)
json endoded =
{"abc":1,"def":["marketing_campaign_id","status","status"],"ghi":[ "eg","eq","eq"]}
