Re: [Tiki-devel] PHP module problem with 27.1 - RE: Tiki-27.1 Release

Hi Geoff

Looks like that bit of code tests for `function_exists('posix_getuid')` but then uses both `posix_getuid` and `posix_getpwuid`, which it didn't check for (and what your error shows).

So maybe that's it?

Those lines have been in installlib.php since 2021 (so it's the same in 24.x), same for the code in tikisetup.class.php - so i think the fix would be to check for both functions or check for the extension... although the manual says:

> This extension is enabled by default. It may be disabled by using the following option at compile time: --disable-posix


So sounds like your hosting company has done something a bit unusual in blocking just `posix_getpwuid`, but we can improve the test by checking for both functions which should fix this (any volunteers? ;)
