According to my research on the subject.
I think the PHP interpreter takes source and convert to CGI and C.
What do you think about this?
Thanks

How does PHP interpreter work?
Hello,
I decided to ask this question here on bytes.com after I googled and retrieved nothing from the different search queries I did.
To make my question more clear I'd like to mention here my own understanding of how C compiler works.
C compiler takes a source file (hello.c e.g) and translate/convert it to assembler after making the links and at the end it makes object file which can be executed by the machine.... -
I solved it, but with a bizarre solution :)
I just have to recall the constructor of DataPlayer, even after doing this in the constructor of UI class.
Example: (see line 10, 18 and 32)
...Code:public class PlayerPanel extends JPanel { private ArrayList<Player> pList; private DataPlayer dp; private Player p; private int identifier = 1;Leave a comment:

It is really bizarre, because when I debug, and get into these lines:
con = db.getConnectio n(); => This works, I get into my database class, and the methode getConnection returns variable c without any problem.Code:con = db.getConnection(); stmt = con.createStatement(); ResultSet rs = stmt.executeQuery(sql);
And here:
stmt = con.createState ment(); ==> It throws exception wich...Leave a comment:

All I know is when I take the barcode reader and scan a barcode, the output is like this in (player_id)
