Can you forward / re-assign the bug maybe so that it is possible to detect this during runtime, please? Please leave a short reply, if you won't do it, so I will do this. ------------------------------------------------------------------------ [2010-10-23 15:19:57] kalle@php.net Hi, sadly the multibyte mode isn't exposed, so the only way to check for it is by sniffing phpinfo() which is really hacky. I wrote up a small script for you to see what I mean by hacky: <?php $zend_multibyte = false; ob_start(); phpinfo(INFO_GENERAL); $buffer = ob_get_clean(); $pos = strpos($buffer, 'Zend Multibyte'); $buffer = substr($buffer, $pos); if(PHP_SAPI == 'cli') { $buffer = ltrim($buffer); $zend_multibyte = (trim(substr($buffer, 25, strpos($buffer, "\n") - 25)) == 'enabled'); } else { $zend_multibyte = (trim(strip_tags(substr($buffer, 28, strpos($buffer, "</tr>") - 28))) == 'enabled'); } unset($buffer, $pos); var_dump($zend_multibyte); ?> As for the documentation, I have added a note on the declare() construct's page that its "impossible" to determine whether the build have multibyte support or not. ------------------------------------------------------------------------ [2010-10-23 15:19:49] kalle@php.net Automatic comment from SVN on behalf of kalle Revision: http://svn.php.net/viewvc/?view=revision&amp;revision=304658 Log: Added remark about zend-multibyte mode, that its only exposed by phpinfo() (Bug #52348) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
