I'm recently trying to profile my Facebook app with php-apd profiler, but i don't have any experience with redhat dest. how to install php-apd profiler under redhat? what is the exact command?
Have you tried simply using: pecl install apd
Since it's a PECL extension, in theory that command should be enough to install it. If that doesn't work, you may be able to find more information on the PHP manual page about installing PECL extensions.
Think you should go through the manual once.
