I have been trying to add an extension xattr (http://php.net/manual/en/book.xattr.php) without much luck.
I have Plesk 12.5.30 and I have successfully install xattr and can see xattr.so in /usr/lib64/php/modules/.
Given that php5.6 modules are in /opt/plesk/php/5.6/lib64/php/modules i have copied xattr.so across to the /opt/plesk/php/5.6/lib64/php/modules.
For the website, within Plesk, I have updated PHP settings and added "extension=xattr.so" under additional directives.
After all that I am still yet to get xattr to work...
My OS is Centos 7 and xattr has chmod 755.
