Php json concatenation-php Tutorial

The question of json concatenation in php is to splice the content in the database into json in the following format. please use the code to describe it.

['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun','Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']

And in this format

 [{            name: 'Tokyo',            data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]        }, {            name: 'New York',            data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]        }]

The json format formed during splicing is incorrect.

hile($row2= sybase_fetch_array($result)){$arr[]=array($row2['outdate']);}

The spelled format is "[]"

[["20140306"],["20140307"],["20140308"],["20140309"],["20140310"],["20140311"],["20140312"],["20140313"]] 

Reply to discussion (solution)

$ Arr [] = $ row2 ['outdate'];

$ Arr [] = $ row2 ['outdate'];

Each array is a pair of []

$ Arr [] = $ row2 ['outdate'];

 [{            name: 'Tokyo',            data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]        }, {            name: 'New York',            data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]        }]

How to splice the format with JS code?

$ar = array(  array(    'name' => 'Tokyo',    'data' => array(7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6),  ),  array(    'name' => 'New York',    'data' => array(-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5),  ),);echo json_encode($ar);

[{"Name": "Tokyo", "data": [7, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6] },{ "name": "New York", "data": [-0.2, 0.8, 5.7, 11.3, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]}]
