php - Get away from MySQL query inside foreach loop. foreach causes issues with while loop? -


i have following code:

<?php //the company_array:  $company_array = array(     "aaa" => "aaa",     "bbb" => "bbb",     "ccc" => "ccc",     "ddd" => "ddd" );  $platform_data = 'pc'; //just keep short :)       foreach ($company_array $company) {     if ($stmt = $mysqli->prepare("select price, time $company platform = ? order time asc")) {         $stmt->bind_param("s", $platform_data);         $stmt->execute();         $stmt->bind_result($price[$company], $time[$company]);         $i=0;         while ($stmt->fetch()) {             $company_info[$company][$i] = array('price' => $price[$company], 'time' => $time[$company]);             $i++;         }         $stmt->close();     } ?>

now had issues this, last iteration of loop seems break, if print $company_info last company displays fine, last 1 seem repeat last value rows:

array ( [aaa] => array     (         [0] => array             (                 [price] => 626.8600                 [time] => 2013-09-27 14:30:06             )          [1] => array             (                 [price] => 615.5900                 [time] => 2013-09-27 15:45:05             )          [2] => array             (                 [price] => 604.7400                 [time] => 2013-09-27 17:45:05             )     )  [bbb] => array     (         [0] => array             (                 [price] => 246.7200                 [time] => 2013-09-27 14:30:06             )          [1] => array             (                 [price] => 245.4700                 [time] => 2013-09-27 15:45:05             )          [2] => array             (                 [price] => 244.8300                 [time] => 2013-09-27 17:45:05             )      )  [ccc] => array     (         [0] => array             (                 [price] => 189.0900                 [time] => 2013-09-27 14:30:06             )          [1] => array             (                 [price] => 188.9800                 [time] => 2013-09-27 15:45:05             )          [2] => array             (                 [price] => 188.8900                 [time] => 2013-09-27 17:45:05             )      )  [ddd] => array     (         [0] => array             (                 [price] => 134.3100                 [time] => 2013-10-06 13:30:06             )          [1] => array             (                 [price] => 134.3100                 [time] => 2013-10-06 13:30:06             )          [2] => array             (                 [price] => 134.3100                 [time] => 2013-10-06 13:30:06             )     ) )

as can see company aaa, bbb , ccc have different prices , times in each of arrays, company ddd has same value repeated 3 times (the last value in database) when values should different in same way other companies.

now have read doing wrong, instead of using foreach should use implode() on array , use that, confusing me since can not find example used on field (seems used on where)

my question be, how can away using foreach loop since seems causing issues, , use proper implode() method on field?

i guessing need modify while loop output remains in same format.
