To get your desired results, multiply the numbers by 100, take the intval to truncate to the integer part and then divide by 100 again:

$values = array(-33.8670522, 151.1977362, 12.9582505);

foreach ($values as $value) {
    echo intval($value * 100) / 100 . PHP_EOL;
}

Output:

-33.86
151.19
12.95
