substitute array keys

[Merlin 🤖]

Hi,

I’d like to substitute array keys but I’m new to PHP and I don’t know how to do it – I was hoping you could help.

The source array looks like this:

"user_cards": {
		"1": {
			"num_owned": "9",
			"num_used": "0"
		},
		"2": {
			"num_owned": "0",
			"num_used": "0"
		},
		"3": {
			"num_owned": "0",
			"num_used": "0"
		},
		"4": {
			"num_owned": "8",
			"num_used": "0"
		},
		"5": {
			"num_owned": "11",
			"num_used": "0"
		}

I’d like to substitute the keys “1,2,3,4,5” etc. with the array values from a txt file called db.txt

That array looks like this: 

<?php
$d[1] = array("Infantry",0);
$d[2] = array("Infantry",2);
$d[3] = array("Infantry",3);
$d[4] = array("Bazooka Marine",0);
$d[350] = array("Bazooka Marine",2);
$d[351] = array("Bazooka Marine",3);
$d[5] = array("Medic",0);
?>

so my current output of

 

1

2

3

4

5

 

would be replaced with

 

Infantry

Infantry

Infantry

Bazooka Marine

Medic

 

this is what I have so far:

<?php
error_reporting(E_ALL|E_STRICT);
ini_set('display_errors', true);

include_once('db.txt');

$json = file_get_contents("TU.json");

$json = json_decode($json, true);



 foreach ($json['user_cards'] as $row => $v)
     {
     echo "$row<br>";
//     foreach ($v as $key => $val)
//         {
//         echo "$key : $val'<br>";
//         }
    
}
    
?>

I don’t know if this’ll make a difference to any advice you may offer but I will be trying to append the value from "num_owned" to each name too.

Change

echo "$row<br>";

To

echo "{$d[$row][0]}<br>";
