Perhaps those two lines are the same in JS and PHP (I do not have PHP installed so I can't confirm, but I do have node installed):

    > 9223372036854775807 == 9223372036854775808
    true
    > 9223372036854775807 === 9223372036854775808
    true

However, that is not the two lines written about in this post. The following works as one would expect on JS, but (I assume, based on the report) not in PHP:

    > "9223372036854775807" == "9223372036854775808"
    false
    > "9223372036854775807" === "9223372036854775808"
    false

ah, I see. I missed that. I just checked in chrome's console and see false for both when they're strings.
