Webserver down: "Invalid command ‘php_value’"

Well this one took me by surprise I’ll say. It’s never fun when Zabbix lights up saying half of your websites have dropped out! Starting httpd: Syntax error on line 31 of /etc/httpd/conf.d/php.conf: Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration [FAILED] Firstly DO NOT comment out the bottom two lines as some sites have recommended. The reason being this will allow your webserver to start up however PHP will not be processed, dumping all of your site’s code into the browser as plain text for anyone to see!
