How to decode json file in php? -

-

i want data json. json file 

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

i want data "test demo" create code 

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

but not working. doing wrong please me on this..

json not valid, doesn't allow several commas in row. changing 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.
