I’m definitely not gonna forgive you for going offtopic, I’m afraid. Because, there’s nothing to forgive! Lol!
Thank you for drawing my mistake to my attention about the php tags missing within the iframe tags!
You saved me from being gumpy tonight, like I was on my birthday yesterday for failing to finish my social network due to this mistake of mine! I won’t bother re-writing about it. You can read more about it here on what I replied to spaceshiptrooper and you will learn why I fussed about php.net and why I was urgently looking for a php 7 tut site and ignoring php 5 tut sites:
Re: Which Php 7 Tutorials Do You Recommend To Complete Beginners? - #28 by uniqueideaman
I’m feeling refreshed now and gonna go out. Tonight will be a better programming night than the last few nights. 
PS - I copied those html from youtube video tuts.
PPS - If you really wanto to know how much php I actually know, then glance upto the VARIABLES section here:
http://php.net/manual/en/
Only managed to finish the VARIABLES section on mid Jan then moved onto youtube tuts. Now, will return to the php.net and continue my learning php. I only took a shortcut to youtube tuts to find the necessary codes to finish my SN. I think I now pretty much have acquired the most needed ones but that won’t stop me from bugging again on this forum when I encounter more problems. Lol!
Thanks again Samuel or is it Samantha (cheek!). Lol!
