[PHP] Command-Line TicTacToe

2008-03-24T00:00:15+00:00

Just wondering if there are any ways to make this smaller.

<?php
$std = fopen("php://stdin", "r");
echo "TICTACTOE\n\n\n\n";
function letsSeeUm($taken){
  foreach(range(1, 9) as $i) ${"s" . $i} = array_key_exists($i, $taken) ? $taken[$i]:" ";
  echo "   +   +   \n $s1 + $s2 + $s3 \n   +   +   \n+++++++++++\n   +   +   \n $s4 + $s5 + $s6 \n   +   +   \n+++++++++++\n   +   +   \n $s7 + $s8 + $s9 \n   +   +   \n\n";
}
function check($squ, $em = "x"){
  if(($squ[1] == $em && $squ[2] == $em && $squ[3] == $em) || ($squ[4] == $em && $squ[5] == $em && $squ[6] == $em) || ($squ[7] == $em && $squ[8] == $em && $squ[9] == $em) || ($squ[1] == $em && $squ[4] == $em && $squ[7] == $em) || ($squ[2] == $em && $squ[5] == $em && $squ[8] == $em) || ($squ[3] == $em && $squ[6] == $em && $squ[9] == $em) || ($squ[1] == $em && $squ[5] == $em && $squ[9] == $em) || ($squ[3] == $em && $squ[5] == $em && $squ[7] == $em)) return true;
  return false;
}
$squares = array();
$player = 1;
while(1){
  echo str_repeat("\n", 100);
  letsSeeUm($squares);
  echo "Player $player> ";
  $input = (int) fgets($std);
  if(!array_key_exists($input, $squares) && in_array($input, range(1, 9))){
    $squares[$input] = ($player == 1) ? "x":"o";
    if(check($squares) || check($squares, "o")){
      echo str_repeat("\n", 100);
      letsSeeUm($squares);
      echo "\nPlayer $player Wins!";
      die;
    }
    if(count($squares) == 9){
      echo str_repeat("\n", 100);
      letsSeeUm($squares);    
      echo "\nDraw!";
      die;
    }
    $player = $player == 1 ? 2:1;
  }
}

2007-12-12T23:40:53+00:00

<?php
$domains = array();
$ref = $_SERVER['HTTP_REFERER'];
if (substr($ref, 0, 33) != "http://www.thegrandtournament.com"){
	$myFile = "log.txt";
    $parsed = parse_url($ref);
    if(!in_array($ref, array_map("trim", file($myFile))) && !in_array($parsed['host'], $domains)){
	    $fh = fopen($myFile, 'a') or die("can't open file");
	    $stringData = $ref."\n";
	    fwrite($fh, $stringData);

[PHP] On Output div block with PHP conditional statement

2007-12-07T19:31:50+00:00

This is one way to shorten it

<?php 
echo (the_ID() == 8) ? '<div id="menu_show" class="slideshow"><img src="http://example.org/image.gif" alt="A picture" width="748" height="245" /></div>':'<div class="header"></div>';
?>

[PHP] On dynamic select box

2007-11-28T10:51:06+00:00

This should do it.

<?php
echo '<select name="options">';
foreach(array("option1", "option2", "option3") as $i){
    $select = ($_GET['options'] == $i) ? ' selected="selected"':'';
    echo '<option value="'.$i.'"'.$select.'>'.$i.'</option>';
}
echo '</select>';

[PHP] On Message system IP-ban

1) You should using true and false as booleans, not strings
2) It should be a double equal sign (==), not a single, in the if statements.

That's pretty good. You should post that up on:

[PHP] On making user html input secure

2007-10-13T00:50:01+00:00

That cleans all of the $_POST values. Example usage below.

<?php
if(isset($_POST['asdasd'])){
foreach($_POST as $pname => $pvalue){
    $_POST[$pname] = str_replace(array("\\", '\\'), array("\'", '\"'), htmlspecialchars(trim($pvalue)));
}
print_r($_POST);
}else{
?>
<form action="" method="post">
<input name="asdasd222" value="ssssssssssss" />
<input name="asdasdas" value="ssssq42345'''" />
<input name="asdasdastt" value="ssssq42345'''" />
<input type="submit" name="asdasd" value="test" />
</form>
<?php
}

[PHP] On Content Page Include

2007-10-01T16:55:15+00:00

This should work. I added the in_array so they can only include certain things.

<?
$page = $_GET['page'];
$pages = array("news", "about");
if(in_array($page, $pages)){
include($page.".php");
}
?>
