Description: ------------ (This Bug is the same as #14580 [Closed]) Using null bytes in array keys doesn't work correctly, the key gets cut off at the null byte. (normal strings work, and array values work, too) I'm updating to 4.3.3-RC1 right now; if it doesn't work there too, i'll try 5.0.0-Beta1 !!!!!!!!!!!!!!!!!!!! Bug #14580 says this should be fixed, but it isn't (at least in 4.3.2-RC2); therefore I'm re-posting this -------------------- System Information: Apache 2.0.46 running on Linux 2.4.20, LFS system glibc 2.3.1, gcc 3.2.2 First block from phpinfo(): PHP Version 4.3.2-RC2 System Linux charon 2.4.20-eq1-cx #4 Mit Jan 29 16:07:00 CET 2003 i686 Build Date May 12 2003 14:43:04 Configure Command './configure' '--prefix=/opt/apache_2.0.45' '--with-apxs2=/opt/apache_2.0.45/bin/apxs' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-mbstring' '--enable-mbregex' '--enable-sockets' '--enable-xslt' '--with-openssl' '--with-zlib' '--with-bz2' '--with-dom' '--with-dom-xslt' '--with-dom-exslt' '--with-mysql=/usr/local/mysql' '--with-xslt-sablot' '--with-snmp' '--with-imap=/usr' '--with-gd=/usr' '--with-png-dir=/usr' '--with-jpeg-dir=/usr' '--with-freetype-dir=/usr' '--with-ldap' '--with-gmp' '--with-iconv' '--with-xmlrpc' '--with-db3=/usr/local/BerkeleyDB.3.3' '--enable-shmop' Server API Apache 2.0 Handler Virtual Directory Support disabled Configuration File (php.ini) Path /opt/apache_2.0.45/lib PHP API 20020918 PHP Extension 20020429 Zend Extension 20021010 Debug Build no Thread Safety disabled Registered PHP Streams php, http, ftp, https, ftps, compress.bzip2, compress.zlib Reproduce code: --------------- <? $text = "abcd\0efgh"; echo strlen ($text) . ": $text\n"; $ar = array ("abcd\0efgh" => "value\0works"); foreach ($ar as $key => $val) echo strlen ($key) . ": $key => " . strlen ($val) .

This same behaviour is with PHP 5.0.0b2-dev too. FYI: This bug is NOT the same as bug #14580. (It was about key() function, which still works fine)

This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better.
