#36867 [NEW]: sqlite_escape_string on '' or null returns wrong value

From: mpb dot mail at gmail dot com Operating system: FreeBSD 4.x PHP version: 4.4.2 PHP Bug Type: SQLite related Bug description: sqlite_escape_string on '' or null returns wrong value Description: ------------ sqlite_escape_string on '' (the empty string) or null returns the wrong value. I would guess that: sqlite_escape_string ('') should return '', and sqlite_escape_string (null) should return null. Additionally, you can see that what sqlite_escape_string actually does return in these cases is a mangled version of the previous non-null input string. This bug appears to have been fixed in PHP5, but not yet in PHP4. http://bugs.php.net/bug.php?id=29339 http://bugs.php.net/bug.php?id=29395 Reproduce code: --------------- <?php print bin2hex (sqlite_escape_string ('xxx')). "\n"; print bin2hex (sqlite_escape_string ('')). "\n"; print bin2hex (sqlite_escape_string (null)). "\n"; print "done\n"; ?> Expected result: ---------------- 787878 done Actual result: -------------- 787878 ac7878 ac7878 done -- Edit bug report at http://bugs.php.net/?id=36867&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36867&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36867&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36867&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36867&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36867&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36867&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36867&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36867&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36867&r=support Expected behavior: http://bugs.php.net/fix.php?id=36867&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36867&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36867&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36867&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36867&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36867&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36867&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36867&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36867&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36867&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36867&r=mysqlcfg
