How to get data from multi dimensional array - php

Question

( Full pastebin: https://pastebin.com/C4qV5YYv)
I'm trying to select data from a (long) multi dimensional array, but with all things I tried the page just showed as blank. I'm trying to access the data with the name instead of it's rank in the list.
{
"playerstats": {
"steamID": "76561198035223060",
"gameName": "ValveTestApp260",
"stats": [
{
"name": "total_kills",
"value": 38694
},
{
"name": "total_deaths",
"value": 33362
},
{
"name": "total_time_played",
"value": 2148546
},
{
"name": "total_planted_bombs",
"value": 770
},
{
"name": "total_defused_bombs",
"value": 271
},
{
"name": "total_wins",
"value": 12394
}, So on and so on......
I'm currently using this to get data from the array: $kills = $jsonforgame['playerstats']['stats'][0]['value'];
This works when you only need a couple of values, but it gets really tidy when I need to select values further down, like; $hit = $jsonforgame['playerstats']['stats'][47]['value'];
Is there anyway for me to select the stats with the name, like this: $hit = $jsonforgame['playerstats']['stats']['total_shots_fired']['value']; instead of the number.
Thanks in advance.

Answer 1

You may go for something like this:
function getStat($data, $name)
{
return array_filter($data, function($item) use ($name) {
return $item && $item['name'] === $name;
})[0]['value'];
}
$hit = getStat($jsonforgame['playerstats']['stats'], 'total_shots_fired');
But the more efficient way would be to change your stats api so it serves key-value pairs, if it is possible, ofc.

One way would be to change how you create the array as so:
{
"playerstats": {
"steamID": "76561198035223060",
"gameName": "ValveTestApp260",
"stats":
{
"total_kills": 38694,
"total_deaths": 33362,
"total_time_played": 2148546,
...
}
then simply access by $kills = $jsonforgame['playerstats']['stats']['total_kills']

Answer 3

In case you can't change the array, you could also try
$specs = array("total_kills", "total_deaths", "total_time_played"); // and so on
foreach ( $specs as $spec )
$$spec = $jsonforgame['playerstats']['stats'][ $spec ]['value'];
After that you can use each spec by name, for example $total_kills
If you want to use shorter variable names you can change the code like this
$specs = array(
"kills" => "total_kills",
"died" => "total_deaths",
"played" => "total_time_played"
); // and so on
foreach ( $specs as $key => $spec )
$$key = $jsonforgame['playerstats']['stats'][ $spec ]['value'];
echo $kills; // output $jsonforgame['playerstats']['stats']['total_kills']['value']
Another approach
$count = count($jsonforgame['playerstats']['stats']);
for ( $i = 0; $i < $count; $i++ ) {
$name = $jsonforgame['playerstats']['stats'][ $i ]['name'];
$value = $jsonforgame['playerstats']['stats'][ $i ]['value'];
$$name = $value;
}
and with use of the array with shorter variable names
$specs = array(
"total_kills" => "kills",
"total_deaths" => "died",
"total_time_played" => "played",
); // and so on
$count = count($jsonforgame['playerstats']['stats']);
for ( $i = 0; $i < $count; $i++ ) {
$name = $specs[ $jsonforgame['playerstats']['stats'][ $i ]['name'] ];
$value = $jsonforgame['playerstats']['stats'][ $i ]['value'];
$$name = $value;
}
