you have same fun qoutes in the begin of string change “ to "

change $GET to$_GET in line 469

remove single qvotes around the filename in your query $transfer = mysql_query("UPDATE members SET balance = '$newblanceto' WHERE bankaccount='$to_acct'") or die ("could not write to profile");

use implode() function

<?php $i = 1; foreach ($_POST['chk_b'] as $index => $option) { echo $option, '<br>'; $fields[$i] = "`EXP$i`"; $value[$i] = "'$option'"; $i++; } //echo $sql = "INSERT INTO table_name (". implode(', ', $fields). ") VALUES (". implode(', ', $value). ")"; ?>

change chkbox name and add value attribute $tmp[] = '<li id="li' . $i . 'b"><label for="chk' . $i . 'b"><input name="chk_b[' . $i . ']" id="chk' . $i . 'b" type="checkbox" value ="'.$option.'"onchange="Enable(\'chk' . $i . 'b\',\'li' . $i . 'b\')">' . $option . '</label></li>'; and on submit page do foreach $_POST['chk_b'] as $index => $option) echo $index, ' -> ', $option, '<br />\n';

number $s is overflow integers (try to echo it) to fix it use modulo operator in calculating $s <?php for ($i = 2; $i < 10; $i++) { // testing from (2^2 - 1) to (2^10 - 1) $s = 4; $m = pow(2, $i) - 1; // define M if ($i > 2) { // Start computing $s only if ($i - 2) > 0, otherwise $s remains equal to 4. for ($j = 1; $j <= $i - 2; $j++) { // Find S(p-2) $s = (($s * $s) - 2) % $m; } } if ($s == 0) { echo "<br />$m"; } // Print out detected prime number. } ?>

for e-mail $pattern = '/From:.*?([A-Za-z0-9!#$%&\'*+-\/=?^_`{|}~\.]+@[A-Za-z0-9!#$%&\'*+-\/=?^_`{|}~\.]+)/';

add space after +1 change +1. to +1 .

$_GET['submit'] is nut array try print_r ($_GET); // test display form values foreach ($_GET as $key => $value) { echo '<br/>'.$key.'<br/> '; if($key != 'submit'){ foreach ($value as $iKey => $iValue) { // Line 72 foreach ($iValue as $xKey => $xValue) { echo " The $xKey for Player $iValue is $xValue <br/>"; } } } }

change echo "<input type='checkbox' name='option".$i."' value='$objectname' checked>".$objectname; to echo "<input type='checkbox' name='option[".$i."]' value='$objectname' checked='checked'>".$objectname; and in $_GET['option'] is array of checked object

i wrote just pseudo code in pascal notation php code looks like $trials = 2; // Number of trials $upgradeChance = 0.5; // Original percent rate of success 50% $rateSuccess = 0; // Total rate of success is 3 of 4 $rateSuccess = 1 - pow((1 - $upgradeChance), $trials) ; echo "Chance of Success: <b>".$rateSuccess * 100 ."%</b><br>";

try to use mysql function STR_TO_DATE() http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_str-to-date

chance_for_n_tries = 1 - (1 - chance)^n for example chance is 1-(1-0.0096)^100

your query is wrong try something like $query = "SELECT * FROM users WHERE username = '$user_username' AND `password` = '$user_password'";

<? if ($_SESSION['memberid']!= 1000) include("themes/".$setts['default_theme']."/includes/side_nav/inc_side_nav_members_menu_tree.php"); ?> <? if ($_SESSION['memberid']== 1000) { ?> <? include("themes/".$setts['default_theme']."/includes/side_nav/inc_side_nav_members_menu_tree2.php"); ?>

you must escape . (dot) too /^[1-9]?((\.|,|\'|\s)([0-9]{1,2}))$/
