Integer overflow for 64 bit platform
If PHP encounters a number beyond the bounds of the integer type, it will be interpreted as a float.
This above general rule differs depending on whether a 32 bit or 64 bit platform is used, which is described as follows.
Platform:32 bit,Range: -2^31-1 to 2^31-1,Numbers:-2147483647 to 2147483647
Platform:64 bit,Range: -2^63-1 and 2^63 -1,Numbers:-9223372036854775807 to 9223372036854775807
<?php
$large_number=9223372036854775807;
var_dump($large_number);
// output: int(9223372036854775807)
$large_number = 9223372036854775808;
var_dump($large_number);
// output: float(9.2233720368548E+18) as 9223372036854775808
//2^64-1 is 18446744073709551615
var_dump(0xffffffffffffffff);
// output: float(1.844674407371E+19) as 18446744073709551615
?>
