Board state is stored in $b in numeric values of 0 (nothing), 1 (one person) and 2 (other person). $m keeps track of whose move it currently is, and is multiplied by -1 each turn. The board check is as follows:
for ($i = 0; $i < 3; $i++) { if ($b[$i][0] == $m && $b[$i][1] == $m && $b[$i][2] == $m) { &win( +$m); } if ($b[0][$i] == $m && $b[1][$i] == $m && $b[2][$i] == $m) { &win( +$m); } } if ($b[0][0] == $m && $b[1][1] == $m && $b[2][2] == $m) { &win($m); } if ($b[0][0] == $m && $b[1][1] == $m && $b[2][2] == $m) { &win($m); }
It requires one loop and four check lines.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
