Bug #66682 [NEW]: FILTER_VALIDATE_INT fails on strings starting with zero.

From: alex dot howansky at gmail dot com Operating system: Linux 2.6 64 PHP version: 5.5.9 Package: Filter related Bug Type: Bug Bug description:FILTER_VALIDATE_INT fails on strings starting with zero. Description: ------------ FILTER_VALIDATE_INT fails on '01'. I can understand that opinions might be divided on whether this should return 1 or false -- however, in either case, the behavior of FILTER_VALIDATE_FLOAT should match, and it doesn't. Test script: --------------- var_dump(filter_var('01', FILTER_VALIDATE_INT)); var_dump(filter_var('01', FILTER_VALIDATE_FLOAT)); Expected result: ---------------- int(1) double(1) or: bool(false) bool(false) Actual result: -------------- bool(false) double(1) -- Edit bug report at https://bugs.php.net/bug.php?id=66682&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66682&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66682&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66682&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66682&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66682&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66682&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66682&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66682&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66682&r=support Expected behavior: https://bugs.php.net/fix.php?id=66682&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66682&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66682&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66682&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66682&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66682&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66682&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66682&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66682&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66682&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66682&r=mysqlcfg
