store $key as array weird result

Question

$highest = max($data);
$check = array();
$resultype = array();
foreach($data as $key => $value){
if($value === $highest){
echo $key;

//output (t1,t3);

$check = $key;
}
}

echo $check; 

//ouput(t3);

Why is it working when I store the $key into a array ?
When I echo in $key in foreach I get what I want (t1,t3) but when I store into and array and output it out side foreach, it only give me (t3).
How do I fix this and store $key into a array with the result I wanted?

you can get the all key as an array without loop by `array_keys` function. php.net/manual/en/function.array-keys.php — Md. Sahadat Hossain, May 13 '15 at 08:13

You're not storing $key in the array, you're assigning it to the variable $check.

Try using $check[] = $key;.
