Installing php-soap with yum and pear both fail

Question

I am trying to install the SOAP extension for PHP on a Centos 6.4 server. I am fairly unfamiliar with package managers, installing packages from the CLI and configuring them within PHP. I am fairly competent with managing the php.ini and other PHP config files (soap.ini etc).

I have tried installing this using the command:

yum install php-soap

but this gives me the following error:

yum install php-soap
Loaded plugins: downloadonly, fastestmirror

I have also tried to install the SOAP extension using pear:

sudo pear install SOAP-0.13.0

This claims that the extension was installed successfully:

install ok: channel://pear.php.net/SOAP-0.13.0

However, despite having added a 'extension=soap.so' line to my php.ini SOAP still does not show up in my phpinfo(). I also get the following error when running 'php -v' or 'pear info SOAP-0.13.0' from the command line:

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

It would seem that there is no soap.so file within '/usr/lib64/php/modules/' or anywhere else on the server, I have checked using:

cd /
find -name soap.so

I have uninstalled and re-installed a couple of times and its the same every time.

Can anyone offer any explanations as to why either of these methods is failing? Happy to provide additional details if required.

Answer 1

Based on the comments above of @EtanReisner I have now been able to successfully install the SOAP package.

The issue was that I had a mix of PHP packages from both the EPEL and IUS repositories. As can bee seen from the above

yum list installed | grep php

Most of these PHP packages are from the IUS repository, it would seem that the php-soap package I was trying to install using

yum install php-soap

Was an EPEL based package, hence the conflict highlighted on the php-common file. As per the suggestions above I have run the following

yum list | grep ^php54

The results of which contain a more appropriate IUS based PHP SOAP package:

php54-soap.x86_64                         5.4.36-1.ius.el6              ius   

Having already uninstalled any of the failed installations of the SOAP package left behind by my initial attempts I then ran

yum install php54-soap

Which installed first time with no issues what so ever.

I have not found any solutions to the second part of this question regarding why the PEAR based package manager failed to install the package successfully.
