PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/memcached.so' - /usr/lib64/php/modules/memcached.so

Question

I'm working with CentOS 6.5

When I'm executing this php -v

I'm getting the below message:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/memcached.so' - /usr/lib64/php/modules/memcached.so: cannot open shared object file: No such file or directory in Unknown on line 0

Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies

As it seems to be a memcached error, when I'm trying this

yum install memcached.x86_64 php-pecl-memcache.x86_64

I'm getting below mentioned errors:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Answer 1

You have installed php from "remi" repository which is not enabled by default. So you need to enable it to install additional PHP extension, with correct ABI compatibility.

yum --enablerepo=remi install php-pecl-memcache
