Issue PHP CLI Error Unable to load dynamic library '/usr/lib64/php/modules/xmlreader.so'

[Sparky]

PHP CLI is showing the following errors when I try to use PHP from the command line:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/xmlreader.so' - /usr/lib64/php/modules/xmlreader.so: undefined symbol: dom_node_class_entry in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/xsl.so' - /usr/lib64/php/modules/xsl.so: undefined symbol: dom_node_class_entry in Unknown on line 0

The module files exist:

[prod_admin@websrv-prod ~]$ ll /usr/lib64/php/modules/xmlreader.so

undefined symbol: dom_node_class_entry

The xsl extensions require the dom extension which is built shared and hence needs to be loaded first. Make sure that there is something like:

# grep -R dom /etc/php.d/*
/etc/php.d/dom.ini:; Enable dom extension module
/etc/php.d/dom.ini:extension=dom.so
