XML Extension not found

问题

I have centos 6.5 server and when I try to install php extension using pecl I get the following error:

XML Extension not found

All the documentations say that this extension is included by default... Why this error still exists?

回答1:

According to a comment on php.net

Certain Linux distributions do not have this extension included in the minimum PHP package. It can usually be found in one of the "optional" php-* packages.

For CentOS, you will need to run yum install php-xml, which provides this extension.

So please try to install it using:

yum install php-xml

Also check your php.ini and make sure that the extension is not commented out with a ; it should be listed as:

extension=dom.so 

In order to be absolutely sure whether or not a module is enabled you should use phpinfo()
