Hi everyone, I'm having troubles with query from database. I want to select all from one table and select sum from second table in the same time. Is this possible? Here is my script: $conn = mysqli_connect('localhost', 'root', '', 'test'); if (!mysqli_set_charset($conn, "utf8")) { printf("Error loading character set utf8: %s\n", mysqli_error($conn)); } $sql = "SELECT first_id, first_name FROM first"; $sql = "SELECT sum(total) as SumTotal FROM second"; $result = mysqli_query($conn, $sql); while ($data = mysqli_fetch_array($result)) { echo '<tr>'; echo '<th>'.$data['first_id'].'</th>'; echo '<th>'.$data['first_name'].'</th>'; echo '<th>'.$data['SumTotal'].'</th>'; echo '</tr>'; } mysqli_close($conn); Thanks!

Hi everyone, I am still learning to do PHP, please be patient with me. Thank you so much! I am trying to understand how "while loop" work in PHP, or do you recommend me use foreach, for, or do for array list from MySQL database? my Code in PHP: <!doctype html> <html> <head> <title>Test foreach columns</title> <link href="default.css" rel="stylesheet" type="text/css"> </head> <body> <?php $Garydb = mysqli_connect("XXXXXX","XXXXXX","XXXXXX") or die("Could not connect MySQL Database"); mysqli_select_db($Garydb, "XXXXXX") or die("Could not find Database"); $sql = "SELECT * FROM XXXXXX"; $display = mysqli_query($Garydb, $sql); while($key = mysqli_fetch_array($display)) { echo "<table><tr><td>".$key."</td><td>".$key."</td></tr></table>"; } ?> </body> </html> seem display on website showing "Array Array" 12 row and 2 columns, what I did do wrong?

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?

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 ?
