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 ?> ---- Server IP: 59.162.86.33 Probable Submitter: 121.243.112.74 ---- Manual Page -- http://www.php.net/manual/en/function.domnode-add-namespace.php Edit -- https://master.php.net/note/edit/89679 Del: integrated -- https://master.php.net/note/delete/89679/integrated Del: useless -- https://master.php.net/note/delete/89679/useless Del: bad code -- https://master.php.net/note/delete/89679/bad+code Del: spam -- https://master.php.net/note/delete/89679/spam Del: non-english -- https://master.php.net/note/delete/89679/non-english Del: in docs -- https://master.php.net/note/delete/89679/in+docs Del: other reasons-- https://master.php.net/note/delete/89679 Reject -- https://master.php.net/note/reject/89679 Search -- https://master.php.net/manage/user-notes.php
