#33268 [Opn->Ver]: iconv_strlen works only with a parameter of < 3 in length

I do still get the same problem with latest 5.1 (php-src) from CVS (checked out just 15 minutes ago, 2005-06-08), both with the glibc-provided iconv and the external libiconv (version 1.9.2) <?php $a = iconv_strlen(""); var_dump($a); $b = iconv_strlen("a"); var_dump($b); $c = iconv_strlen("aa"); var_dump($c); $d = iconv_strlen("aaa"); var_dump($d); $e = iconv_strlen("aaaa"); var_dump($e); ?> Notice: iconv_strlen() [function.iconv-strlen]: Unknown error (2) in /usr/local/apache/htdocs/test2.php on line 2 bool(false) Notice: iconv_strlen() [function.iconv-strlen]: Unknown error (2) in /usr/local/apache/htdocs/test2.php on line 5 bool(false) Notice: iconv_strlen() [function.iconv-strlen]: Unknown error (2) in /usr/local/apache/htdocs/test2.php on line 8 bool(false) int(3) int(4) ------------------------------------------------------------------------ [2005-06-08 02:38:56] sniper@php.net And in HEAD (upcoming 5.1) there is no problem. ------------------------------------------------------------------------ [2005-06-08 00:51:52] scott at slerman dot net I confirmed this problem on Fedora using PHP 5.0.4 and Apache 2.0.54. On Windows/PHP 5.0.4 I get Notice: iconv_strlen(): Unknown error (9) in C:\PHP\test\iconv.php on line 1 On Fedora/PHP 5.0.4 CLI I get Notice: iconv_strlen(): Unknown error (25) in /home/scott/test files/iconv.php on line 1 ------------------------------------------------------------------------ [2005-06-08 00:28:48] markus dot lervik at necora dot fi Description: ------------ iconv_strlen seems to have a peculiar bug. It doesn't work when the string searched is less than three characters long (or an empty string), but reports Notice: iconv_strlen() [function.iconv-strlen]: Unknown error (2) in /usr/local/apache/htdocs/test2.php on line 7 This is tested on PHP 5.0.3 and 5.1 from CVS (2005-06-07), tested with the built-in (glibc 2.3.3) iconv and libiconv 1.9.2 from gnu.org. This problem doesn't seem to surface on my Debian 3.1 development server, but I get it on my SuSE 9.2 desktop. I have tried to set the encodings with iconv_set_encoding() and I have tried to set the encoding as a parameter to iconv_strlen(), both produce the same error. The other iconv-functions (iconv_strpos, iconv_substr, iconv_strrpos) work fine. Since the iconv-functions do not seem to work from the commandline (produces an Unknown error(29)), I cannot get a proper strace (strace seems to say that iconv is trying to seek on /dev/pts/5, which apparently is impossible). It doesn't crash apache either, so I'm not sure where I'd grab the backtrace.
