Edit report at https://bugs.php.net/bug.php?id=73374&edit=1 ID: 73374 Updated by: ajf@php.net Reported by: nikic@php.net Summary: intval() with base 0 does not detect binary Status: Open -Type: Bug +Type: Feature/Change Request Package: Math related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: 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. Previous Comments: ------------------------------------------------------------------------ [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
