I have a tic tac toe game that I've been working on for a school project. When I attempt to run it a parse error comes up saying "syntax error, unexpected $end" on line 311. If anyone wants to try and run it. go here http://itstudents.ccs.uconn.edu/~iskm218st38/newnewnewtictactoe.html I'm trying to make the computer randomly select a tile after the human player selects but the first issue I need help with is why i'm getting this syntax error on a line that doesnt have code on.

 

This is the html gameboard

There is no closing bracket } for the function check_input().  When you see "unexpected $end" it is usually a bracket problem.  There are many other problems with the script though.

 

1. $rand_keys is not defined.

2. case statements make no sense.  You are echoing the $_POST['box#'] no matter what the case is, so there is no need for it.

3. concantenation in PHP is with the period( . ) not with the plus sign (+).
