Bug #14684 Updated: pack doesn't correctly handle zero integer values

ID: 14684 Updated by: mfischer Reported By: someone@records.ru Old Status: Open Status: Bogus Bug Type: Unknown/Other Function Operating System: Linux 2.2.18 PHP Version: 4.1.0 New Comment: There's nothing wrong with pack, neither CGI nor apache. I guess your client can't handle this. You can verify this youself with: <? $foo = pack('L', 0); $f = fopen('/tmp/pack', 'wb'); fwrite($f, $foo); fclose($f); ?> $ hexdump /tmp/pack 0000000 0000 0000 0000004 As you can see, it's perfectly valid (tested with apache, mod_php). Previous Comments: ------------------------------------------------------------------------ [2001-12-24 05:34:20] someone@records.ru I've just compiled CGI version, it works fine, output is "\x00\x00\x00\x00". Also here's my configure string from phpinfo: './configure' '--with-apxs=/www/bin/apxs' '--with-mod_charset' '--without-pear' '--with-zlib' '--with-bz2' '--with-mysql=/usr' '--disable-xml' make CFLAGS="-DHAVE_MYSQL_MYSQL_H -I/www/include" ------------------------------------------------------------------------ [2001-12-24 05:09:46] someone@records.ru <?= pack("L",0); ?> On PHP 4.1.0, compiled as Apache shared module outputs string "\x20\x20\x20\x20" (4 spaces). It is not "L"-specific issue. <?= pack("C",0); ?> also outputs "\x20". Any non-zero values are processed OK. PHP 4.0.1pl2 and 4.0.6 seems to work correctly. Configuration includes --with-apxs, --with-mysql (bundled), --with-bz2, --without-xml and --without-pear. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14684&edit=1
