From: trevor at corevx dot com Operating system: Solaris / OS X PHP version: 5.2.1 PHP Bug Type: Strings related Bug description: addcslashes has unexpected behavior with binary input / string terminator
Description: ------------ When the input to addcslashes contains a NULL character (string terminator, \000) the resulting output is terminated at that point if the NULL character is not deliberately escaped. This makes it impossible to use addcslashes for certain special cases with binary data. If fixed it would be a much more powerful tool. Reproduce code: --------------- # Last pair demonstrates issue $str = "a\000z"; echo $str; # => az strlen( $str ); # => 3 addslashes( $str ); # => a\0z strlen( addslashes( $str ) ); # => 4 addcslashes( $str, "\000z" ); # => a\000\z strlen( addcslashes( $str, "\000z" ) ); # => 7 addcslashes( $str, "z" ); # => a strlen( addcslashes( $str, "z" ) ); # => 1 Expected result: ---------------- echo addcslashes( $str, "z" ); # => a\z strlen( addcslashes( $str, "z" ) ); # => 4 -- Edit bug report at http://bugs.php.net/?id=40915&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40915&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40915&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40915&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40915&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40915&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40915&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40915&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40915&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40915&r=support Expected behavior: http://bugs.php.net/fix.php?id=40915&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40915&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40915&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40915&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40915&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40915&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40915&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40915&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40915&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40915&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40915&r=mysqlcfg
