XenForo Add version Number to Footer
PCRE (PHP <7.3)
If using XenForo create a TMS (template adaption) for 'footer', select RegExp and enter this. Possibly you have to replace the \n in the substitution with real new lines so just press enter there.

Simple Telephone number regex
PCRE (PHP <7.3)
It accepts phone numbers of the form 0XX XXX XX XX (stylized here, it doesn't really accept spaces). Also, it can detect the international area code (e.g. +41 OR 0041 for Switzerland). It's not a good idea to rely on the groups (because they do not work for this reason. At ALL.
