Bug #72095 [Opn]: Undefined constant GLOB_BRACE while doc-base/configure.php

Edit report at https://bugs.php.net/bug.php?id=72095&edit=1 ID: 72095 Updated by: cmb@php.net Reported by: rogeriopradoj@php.net Summary: Undefined constant GLOB_BRACE while doc-base/configure.php Status: Open Type: Bug Package: Doc Build problem Operating System: Alpine Linux PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Setting GLOB_BRACE to 0 obviously deactivates the advanced features of glob()[1]. Either GLOB_BRACE is necessary, or not. In the latter case we simply can remove the flag; in the former we'd break the code.

PHP Notice: Use of undefined constant GLOB_BRACE - assumed 'GLOB_BRACE' in /php-manual/doc-base/configure.php on line 573 PHP Warning: glob() expects parameter 2 to be long, string given in /php-manual/doc-base/configure.php on line 573 PHP Warning: Invalid argument supplied for foreach() in /php-manual/doc-base/configure.php on line 573 --- The message "All good. Saving .manual.xml… done." is shown in the end, anyway we could make these errors disappear. Researching a little I found that this happens in Alpine Linux because seems that it doesn't support GLOB_BRACE since it is using musl libc instead of GNU libc. > https://github.com/zendframework/zend-stdlib/issues/58 The workaround is not hard to implement (https://github.com/zendframework/zend-stdlib/pull/59): Instead of using directly ... GLOB_BRACE ... it's just to check if it's defined before otherwise defaults to 0, like this: ... defined('GLOB_BRACE') ? GLOB_BRACE : 0 ... As shown above, it's the way the issue was solved in Zend Framework. --- As Alpine Linux is going to get more attention mainly because of Docker based environments because it's very lightweight (https://www.brianchristner.io/docker-is-moving-to-alpine-linux/), I guess this workaround proposed is worth to have here as well. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72095&edit=1
