Basically you can just cast your array in object

$newData = (object) $data;

Or use the stdClass

$newData = new stdClass();
foreach ($data as $key => $value)
{
    $newData->$key = $value;
}

If you want an array of objects, you could use array_map:

$data = array_map(function($x) {
    return (object)[
        "time" => $x[0],
        "value" => $x[1]
    ];
}, $data);

You extremely don`t need nested foreach. You can use amazing built-in php function such as array_combine().

There are 3 options how to do that (can be more if you are creative person :D)

$keys = ['time', 'value'];

/** 1 option */
foreach($data as $value){
    $newData[] = array_combine($keys, $value);
}

/** 2 option */
foreach($data as $key => $value){
    $data[$key] = array_combine($keys, $value);
}


/** 3 option */
$newData2 = array_map(function($value) use ($keys){
    return array_combine($keys, $value);
}, $data);

P.S By the way, php supports associative arrays. So, that`s not an object, it is an associative array (array with keys)

[
 [
   'key' => 'value'
 ] 
]
