The value you are using is too large for PHP to handle.

“The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value.”

http://php.net/manual/en/language.types.integer.php

Here is the solution that I tested using strings instead of integers and it works:

$start = (string)$_GET['start'];
$end = (string)$_GET['end'];

for($i = $start; strcmp($i, $end); $i = bcadd($i, 1)){
    echo $i . "<br>";
}
