How to refer to data in an array (php/json) - php

Question

I am obtaining a json object using the following:
$json = file_get_contents("url-here");
$data = json_decode($json, true);
//test
var_dump($data);
This gives me something like this:
array(2) { ["ok"]=> bool(true) ["result"]=> array(1) { [0]=> array(2)
{ ["update_id"]=> int(44893465) ["message"]=> array(5) {
["message_id"]=> int(16) ["from"]=> array(3) { ["id"]=> int(29595794)
["first_name"]=> string(3) "Bob" ["username"]=> string(14) "Bobo" }
["chat"]=> array(3) { ["id"]=> int(29595794) ["first_name"]=>
string(3) "Bob" ["username"]=> string(14) "Bobo" } ["date"]=>
int(1435354253) ["text"]=> string(7) "/q 3.33" } } } }
I would then like to add certain values into variables. For example I would like to extract username, text, message_id, etc
But no matter what I try my variables are empty:
//let's test it
echo "Username: " . $data[1][0]["username"];
//another test
echo $data->username;
Neither of these are working and my research has not helped me find a solution. I am stumped on this one.
Any pointers in the right direction would really be appreciated.

Answer 1

array(2) {
["ok"]=> bool(true)
["result"]=> array(1)
{
[0]=> array(2)
{
["update_id"]=> int(44893465)
["message"]=> array(5)
{
["message_id"]=> int(16)
["from"]=> array(3)
{
["id"]=> int(29595794)
["first_name"]=> string(3) "Bob"
["username"]=> string(14) "Bobo"
}
["chat"]=> array(3)
{
["id"]=> int(29595794)
["first_name"]=> string(3) "Bob"
["username"]=> string(14) "Bobo"
}
["date"]=> int(1435354253)
["text"]=> string(7) "/q 3.33"
}
}
}
}
You are using wrong array index. $data[1][0]["username"]; not exists.
$data["result"][0]["message"]["from"]["username"];
$data["result"][0]["message"]["chat"]["username"];
This will give you the proper username

Answer 2

$json = file_get_contents("url-here");
$data = json_decode($json, true);
//test
echo $data["result"][0]['message']['from']['username'];
output
Bobo
