enable SOAP on PHP

Question

I would like to enable SOAP on my PHP5/Centos/Apache server. I have full access to the server. My php.ini file includes the below. When I look at phpinfo(), it doesn't reference SOAP. Any suggestions? Thank you

[soap]
; Enables or disables WSDL caching feature.
soap.wsdl_cache_enabled=1
; Sets the directory name where SOAP extension will put cache files.
soap.wsdl_cache_dir="/tmp"
; (time to live) Sets the number of second while cached file will be used 
; instead of original one.
soap.wsdl_cache_ttl=86400

EDIT - Get the following. Tried it on two different servers.

[root@localhost ~]# yum install php-soap

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

Answer 1

In case that you have Ubuntu in your machine try the following in your terminal:

1. sudo apt-get install php-soap
2. service apache2 restart

To check use php test file inside it only the following function phpinfo(); and check results in the browser which contains the following module like that image:

Answer 2

You may need to make sure the PHP SOAP package is installed. Try running yum install php-soap as root.

Edit: Adapted from this excellent answer to a similar question:

run this:

yum --enablerepo=webtatic install php-soap

this tells yum to get the packages from webtatic repository (in addition to system configured repositories). If you want webtatic among system enabled repositories, run:

rpm --import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy
yum --enablerepo=webtatic install  webtatic-release
