I am using spacetree chart and I require JSON in hierarchical format. See sample required JSON format here . I have ID,ParentID,Name,Description fields in Mysql database table. Now How can I convert data in Hierarchical/nested JSON using PHP? I know json_encode($array). But, I require nested/Hierarchical php array for this. Let me know to do this.
You're basically asking two questions here - 1) how to get an hierarchical php structure from a db table and 2) how to encode this structure in json. For the first question see, for example, my (old but working) code . For the second, I believe simple json_encode will work pretty well.
If you have PHP json extension on your server installed, just use it on an array. The steps will be:
If you don't have json_encode enabled on your server and cannot install it... You'll just have to write it by hand.
It'll be something like that (untested code warning) :
function my_json_encode($array)
{
$return = '{';
$count = count($array);
$i = 0;
foreach ($array as $key => $val)
{
$return .= '"'.$key.'" : ';
if (!is_array($val))
$return .= '"'.$val.'"';
else
$return .= my_json_encode($val);
if ($i < $count-1)
$return .=",";
$i++;
}
$return .= '}';
return $return;
}
