ID: 60801 Updated by: ahar...@php.net Reported by: dexen dot devries at gmail dot com Summary: strpbrk() mishandles NUL byte -Status: Open +Status: Assigned Type: Bug -Package: Class/Object related +Package: Strings related PHP Version: 5.3.9 -Assigned To: +Assigned To: aharvey Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2012-01-19 09:37:07] dexen dot devries at gmail dot com Description: ------------ PHP's strpbrk() passes its string arguments directly to libc strpbrk(), which considers NUL byte a string-terminatig character rather than a normal part of the string. note that, in the test script below, the strpbrk() matches neither the NUL byte, nor the `a' character (because it occurs after a NUL byte in $haystack), nor even the `b' character (because it occurs after a NUL byte in $char_list). Test script: --------------- $haystack = "foob\x00ar"; $char_list = "a\x00b"; $v = strpbrk($haystack, $char_list); Expected result: ---------------- $v === "b\x00ar" Actual result: -------------- $v === FALSE ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60801&edit=1
