i have a data.json file that looks like this:
{"price_usd":[
["June 3, 2022",886.754],
["June 5, 2022",899.644],
["June 6, 2022",891.014],
["June 7, 2022",13685.4],
["June 8, 2022",13411]
]
}
I want to add another date + price to this data.json file (inside the price_usd, after june 8), but i dont really know how to do this. Ive looked up different documentations, but all of them had different way to how they formed their JSON. I cannot use another format, since its connected to a graph.
This is what i have (php), but it just wipes the data.json:
$file=fopen("data.json","w");
$array_data=array();
$extra = array("June 10, 2022", 455);
$array_data["price_usd"] = $extra;
$final_data = json_encode($array_data);
fclose($file);
return $final_data;
