[1] <http://php.net/manual/en/function.intval.php> ------------------------------------------------------------------------ [2016-10-22 23:00:27] ajf@php.net I'm recategorising this as a feature request, because intval() isn't inherently tied to PHP's integer literal formats, much as one might wish it were. ------------------------------------------------------------------------ [2016-10-22 21:58:06] nikic@php.net Description: ------------ intval() using base 0 currently detects decimal, octal and hexadecimal numbers based on notation. However, binary numbers are always converted to 0. As PHP supports binary number literals as of PHP 5.4 they should be supported here as well. https://3v4l.org/GYVQa Test script: --------------- var_dump(intval('0b1101', 0)); Expected result: ---------------- int(13) Actual result: -------------- int(0) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73374&edit=1
