Previous Comments: ------------------------------------------------------------------------ [2009-06-08 14:55:11] rquadling@php.net As 1234567890123 is larger than a 32bit integer, it is converted to a float. Once in a float it is quite happily allowed to be incremented as you are using. ------------------------------------------------------------------------ [2009-06-08 14:31:10] headden at karelia dot ru Description: ------------ http://www.php.net/manual/en/language.types.string.php "The string will be evaluated as a float if it contains any of the characters '.', 'e', or 'E'. Otherwise, it will be evaluated as an integer." this statement is wrong, consider the following code: $a = 1 + "1234567890123"; var_dump($a); // outputs 'float(1234567890124)' on a 32-bit platform this means that "1234567890123" was treated as 'float' although it does not have any of '.', 'e' or 'E' characters. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48496&edit=1
