i havent used much of php but the consensus seems to be that it works but it's not the most beautiful code.
I think I'm going to get heavy into data structures and algorithms and mathematics soon. I already know enough languages decently enough. Time to really focus on the knowledge that spans across languages.
@Gonzo I'm made some serious progress since then, I think I got inheritance, abstract, implementation, pointers, fiIeO, etc pat down I think. Last semester, OOP was kicking my ass, I barely pass that class, but now I'm squeezing an A in my data structures and data engineering class, next year graduation.

right now, i'm learning Python
With regards to my post above...
I'm trying to create a while loop that gets data from two seperate database tables. When it does, it does a subtraction between a column from both tables. It checks if the result is over the "limit". If it's not, it prints out a coloumn data from the row.
Here's my code:
I get an error in line 15 saying: "mysql_fetch_array() expects parameter 1 to be resource, boolean given in..."
Can someone tell me where I'm going wrong or how to better excute this code?

I haven't used PHP in years. But in line 15 I think you need to change $result1 to $res1, as that is the name of the variable you declared before. I could be wrong.
You're right, thanks for pointing that out.
However, I still get the same error. :/ I'll keep working on it.

Try changing && to || in line 11 so it displays an error when either of the queries is false.
And in line 15 try adding parenthesis like the following:
Code:
while(($row1 = mysql_fetch_array($result1)) && ($row2 = mysql_fetch_array($res2)))
