How to print keys and values ​​in an array

Question

I'm trying to format my array like this: Name is John, Age is 30. Here is my sample array and code:

$user = array(
    'name' => 'John',
    'age' => 35
);

echo key($user)." is ".($user[key($user)]).","; // prints "name is John,"

If there are no more results to print, the comma (,) will disappear.

I'm not very good at logic, but can you help me? This will be a big help! Thank you in advance.

Answer 1

$user = array(
    'name' => 'John',
    'age' => 35
);

// echo key($user)." is ".($user[key($user)]).",";

$counter = count($user);
$i = 1;
$res = '';

foreach ($user as $key => $value) {
    $res .= $key. " is ". $value;
    if ($counter != $i) {
        $res = $res .", ";
    }
    $i = $i + 1;
}
echo $res;

Answer 2

$values =[];

foreach ($user as $key => $value) {
    $values[] = "{$key} is {$value}";
}
echo implode(', ', $values);

or

$values = array_map(fn($key, $value) => "{$key} is {$value}", array_keys($user), $user);
echo implode(', ', $values);
