how to install posix in php

Question

POSIX does not appear when I run php -m cmd, however, I see it from the phpinfo() –enable-posix=shared on Linux with Plesk 9.

Basically, I can't use posix_*() functions as described at http://www.php.net/manual/en/ref.posix.php

this shows doesn't exists:

if (function_exists('posix_getuid')) {     echo "posix_getuid available"; } else {     echo "posix_getuid not available"; // this prints in my server. } 

Could someone show me how to install it? Thank you.

Answer 1

I found the solution:

yum install php-process 

This package enables php-posix.

Answer 2

While resolved, the original problem would seem to be that posix_getpwuid is not supported on Windows:

from: http://www.php.net/manual/en/function.posix-getpwuid.php

On Windows, posix_getpwuid() is not implemented

• if you just want the username of the current user, you can use get_current_user().

• To properly get the running user, test if function_exists('posix_getpwuid') and if not, assume you're running on Windows and call getenv('USERNAME').
