From: dimedrol at tut dot by Operating system: GNU/Linux i686 2.6.9 PHP version: 5.2.6 PHP Bug Type: Strings related Bug description: strpos() returns varying results Description: ------------ When I run short script below I every time receive different values in output. It may print 7 and may print 11. PHP-file has encoding cp-1251. Here's version info from my webserver -bash-2.05b$ /usr/sbin/httpd -V Server version: Apache/2.0.63 Server built: Jul 22 2008 23:09:16 Architecture: 32-bit Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D HTTPD_ROOT="/usr/local/apache" -D SUEXEC_BIN="/usr/local/apache/bin/suexec" -D DEFAULT_PIDLOG="logs/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf" Reproduce code: --------------- <?php print(strpos('&#1074;&#1072;&#1089;&#1103;12hello[b]','[b]')); ?> it contains cyrillic characters. If I replace them with latin ones everything works fine Expected result: ---------------- I expect 11 to be printed Actual result: -------------- Actual results is sometimes 11 and sometimes 7. 7 looks like cyrillic characters are simply omitted during calculation. -- Edit bug report at http://bugs.php.net/?id=46214&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46214&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46214&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46214&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46214&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=46214&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46214&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46214&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46214&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46214&r=support Expected behavior: http://bugs.php.net/fix.php?id=46214&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46214&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46214&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46214&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46214&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46214&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46214&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46214&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46214&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46214&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46214&r=mysqlcfg
