Doc #52348 [Opn->Csd]: Please document --enable-zend-multibyte configure option

Edit report at http://bugs.php.net/bug.php?id=52348&edit=1 ID: 52348 Updated by: kalle@php.net Reported by: php-bugs at thequod dot de Summary: Please document --enable-zend-multibyte configure option -Status: Open +Status: Closed Type: Documentation Problem Package: Documentation problem PHP Version: 5.3.3RC3 -Assigned To: +Assigned To: kalle Block user comment: N New Comment: 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.

It is mentioned to be a requirement for declare(encoding) [1], but a) apparently the Windows builds do not have it enabled (according to phpinfo output b) I cannot see how this can get detected on runtime (e.g. via some defined function) - I need to know if declare(encoding) processing is being done or not (and convert source files manually if declare(encoding) is ignored).
