For each get a value with a variable key - php

Question

I find it hard to explain but my page has a multidimensional array with all the users and I need to get values from the inner arrays without knowing the main key.
I'm not as experienced with arrays yet and I'm completely stuck right now. The function I use has 2 parameters. The first one is the input id of the user and the second is the array of the complete user list.
function userInfo($i, $users){
foreach($users['data'] as $user){
if($i = $user['id']){
return $user['SOMENAME?']['name'];
}
}
}
Here is a example of the array I'm working with:
{
"data": {
"Doe": {
"id": 266,
"title": "Doe title",
"name": "Doe",
"key": "Some key"
},
"John": {
"id": 412,
"title": "John title",
"name": "John",
"key": "Some key"
}
}
The function I have now simply returns Doe (The first value in the array) no matter how much arrays are in there.
How do I return the title or any of the other values when I don't know the name of the main key for that specific array?

Answer 1

There is an error in your if statement, where you are assigning a value, not ccomparing it (= vs == or ===).
For the purpose of your function, I don't think you need to know the key, because you're already in the array. eg.
function championInfo($i, $users){
foreach($users['data'] as $index => $user){
if($i == $user['id']){
return $user['name'];
}
}
}

Answer 2

foreach($users['data'] as $key => $user){
if($i = $user['id']){
return $champion[$key]['name'];
}
}

Answer 3

foreach($collecion as $key => $val){
That should get your results.

Answer 4

Try this;
foreach ($array as $key => $value) {
echo "ID: {$value['id']}, Title: {$value['title']}, Name: {$value['name']}, Key: {$value['key']}<br />";
}
another version (if you think this is more readable)
foreach ($array as $key => $value) {
list($id, $title, $name, $key) = array_values($value);
echo "ID: {$id}, Title: {$title}, Name: {$name}, Key: {$key}<br />";
}
