This is not a bug, the number you are using is NOT an integer because
it's larger then 2^31-1 (the maximum integer value in PHP) and thus it
will be converted to a float. Use
 
$a[(string)2163195907] = "hi";
echo array_key_exists((string)2163195907,$a);

and it should work fine.

Try this script:

<?php
	$a = array();
	$a[2163195907] = "hi";
	echo array_key_exists(2163195907,$a);
?>

PHP generates a warning (The first argument should be either a string
or an integer). If I try this with smaller integers, the code works
fine. If I convert the integer to a string (using strval), it also
works fine.
