Q: PHP/MySQLi Registration form using procedural mySQLi (not object oriented)

sBucholtzI'm still relatively new to coding with PHP and mySQLi (also first post on codereview). I want to learn more but I'm really limited in resources.

The code does not actually do much, it splits a string, all the other lines do basically nothing since you are not using the variables so it's impossible to know how this could be made clearer/shorter. Anyway use a loop to loop through the items, don't use indexes. What if there are only 19 items? Or more than 20? Also there is codereview.stackexchange.com which is more suited for this question. — Esko 58 secs ago

SO is for when you're stuck and need help to solve a programming issue. "Which way is quickest" isn't really an issue until you have something that is too slow. IMHO, you should start by doing a bunch of research and attempts. If you're unable to create the array, come back, show us what you've tried and we can help. If you are able to create the array, go to Code Review and ask if there's a better (or "quicker") way. Currently, this question is actually more: "I want this. Gimme code". — Magnus Eriksson 1 min ago
It's always 3 steps, but there are ways to make the steps more efficient by using HashSets. Why not show how you're currently doing it. Note: since you're looking for a "better" way this might be a better question on codereview.stackexchange.comjuharr 56 secs ago

it's so stupid, "you're going to be 30 soon" is jumping around in your head tauntingly
and you know that it's not that big of a deal, but it kinda eats at you anyways.
 
I keep recounting events through my life (as one does), I've had 7 people who graduated in my year at my school, or within 2 years before me at my school (125 people total there) die within the last 3 years...that's a lot...makes one think.
 
See I didn't keep track of the people that graduated with me...
 
9:10 PM
5% of my classmates have died within the last 3 years...
 
because I didn't get along with them even remotely well..
 
I didn't either but many of my friends tell me when these things happen.
 
but I'm pretty sure that a colleague of mine from vocational education recently crossed into the last quarter of his thirties

@Peilonrayz Innit? For only being "graduated" for 9 years.
@Vogel612 Yeah, that's why I put the scale lol
 
considering that my "suburb" (part of town) is about 5-7sqmi and about 10k people live there....
 
Saying "county" doesn't mean much, but once you realize that in my area that's 20mi+ by 20mi+, now it's pretty big.

You'll be there in 5-10 years, I'd guess. The more you fret about it, the faster it'll go.
Although it might make it seem longer...
