Bug #73374 [NEW]: intval() with base 0 does not detect binary

From: nikic Operating system: PHP version: Irrelevant Package: Math related Bug Type: Bug Bug description:intval() with base 0 does not detect binary 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 bug report at https://bugs.php.net/bug.php?id=73374&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73374&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73374&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73374&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73374&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73374&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73374&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73374&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73374&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73374&r=support Expected behavior: https://bugs.php.net/fix.php?id=73374&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73374&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73374&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73374&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73374&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73374&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73374&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73374&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73374&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73374&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73374&r=mysqlcfg
