Question

I want to get the data from json. My json file is like this

I want to get the data "test demo" so i create code like this

$html = file_get_contents("jasonfile");
$obj1 = json_decode($html, true);

echo $obj1[][][];

but it does not working. what i am doing wrong please help me on this..

Answer 1

JSON is not valid, it doesn't allow several commas in row. Changing it to:

[[["test demo","",0]],"vi",0.58984375,[["vi"],[0.58984375]]]

And running:

$obj1 = json_decode(...yourinput...); echo $obj1[0][0][0];

correctly outputs test demo .

Answer 2

Try this:

[[["test demo","","","",0]],"","vi","","","",0.58984375,"",[["vi"],"",[0.58984375]]]


$html = file_get_contents("jasonfile");
$obj1 = json_decode($html, true);

echo $obj1[0][0][0];
