Hello so I have a simple code here that will check if a random number already exists in the database and will generate a new one: $rand = mt_rand(100000, 999999); $sid = array( ":sponsorID" => $rand ); $accounts = $db->select("accounts", "sponsorID = :sponsorID", $sid) while(count($accounts) > 0) { $newNum = mt_rand(100000, 999999); } What I wanted to do is to echo out $newNum. When I echo it out I get undefined index of that variable. How can I solve this?

<?php function getFullMonthName($num) { if ($num < 1 || $num > 12) { return "Unknown"; } return ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"][$num - 1]; } $ids = mysqli_real_escape_string($db, $id); $sql = "SELECT * FROM multimedia, keertan WHERE multimedia.id LIKE '$ids' AND keertan.multimediaid LIKE '$ids' ORDER BY k_order ASC"; $result = mysqli_query($db, $sql); $title_list = "xyz"; $done = "xyz"; while ($myrow = mysqli_fetch_array($result)) { $location = $myrow["location"]; $program = $myrow["program"]; $year = sprintf("%04s", $myrow["year"]); $month = sprintf("%02s", $myrow["month"]); $monthName = getFullMonthName($month); $isnew = $myrow["isnew"]; if ($done != "true") { echo "<h3><b>$location $program $monthName $year</b></h3>"; } $done = "true"; while ($title_list != $myrow["title"]) { $title_list = $myrow["title"]; $sublist = $myrow["sub_title"]; echo "<div class=\"panel panel-primary\"><div class=\"panel-heading clickable\"><h3 class=\"panel-title\"><b>$title_list</b></h3>"; echo "<small>$sublist</small><span class=\"pull-right\"><i class=\"fa fa-minus\"></i></span></div><div class=\"panel-sarabveer-table\"><table class=\"table\"><thead><tr><th>Time</th><th>Kirtani</th><th>MP3</th><th>Video</th></thead>"; } if (strtotime($myrow["created"]) > strtotime("3 weeks ago")) { $newed = "NEW"; } elseif (strtotime($myrow["modified"]) > strtotime("3 weeks ago")) { $newed = "UPDATED"; } else { $newed = ""; } printf("<tr><td>%s</td><td>%s <small>%s</small></td>", $myrow["length"], $myrow["keertaneeya"], $newed); $mp3f = urlencode($myrow['mp3_link']); if ($myrow["mp3_link"] != "") { printf("<td><a target=\"_blank\" href=\"http://www.akji.org.uk/multimedia/%s/%s/%s\"><img src=\"images/play.png\" border=\"0\" width=\"25\" height=\"25\"></a></td>", $myrow["location"], $year, $mp3f); } else { echo "<td></td>"; } if ($myrow["rv1_link"] != "") { printf("<td><a target=\"_blank\" href=\"%s\"><img src=\"images/vplay.png\" border=\"0\" width=\"25\" height=\"25\"></a></td></tr>", $myrow["rv1_link"]); } else { echo "<td></td></tr>"; } echo "</table></div></div>"; } ?> So Basically I have this code that displays this page: https://akjmobile.org/keertannew.php?id=532 The problem is that the echo on line 97 runs to early and cuts of rest of the table information, making the other table information be spit out outside of the Bootstrap Panel. How would I fix this?

<?php function factorial($number) { if ($number < 2) { return 1; } else { return ($number * factorial($number-1)); } } function poisson($occurrence,$chance) { $e = exp(1); $a = pow($e, (-1 * $chance)); $b = pow($chance,$occurrence); $c = factorial($occurrence); return $a * $b / $c; } $x = 2.5; $y = 1.5; $calAll = array(); for($z = 0 ; $z <= 9 ; $z++) { array_push($calAll, (poisson($z,$x) * poisson(0,$y))*100, (poisson($z,$x) * poisson(1,$y))*100, (poisson($z,$x) * poisson(2,$y))*100 ); } $value = max($calAll); $key = array_search($value, $calAll); print_r($calAll) . "\n"; echo "max =",$value , " key =",$key . "\n";; ?> it is possible to find $z and the number 0,1 or 2 from the max of the returned array ? I used excel to perform this action and i found that for max=8.5854557290941 the $z is 2 and number 1 how to achieve this in php ?
