php - can't find multiple values in SQL -

i have db full of players , trying create page register them specific tournament. tournament director search players username (which "firstname.lastname").

the problem i'm experiencing when run loop echo each $players[$x] gives id first matching db record, , repeats number once each match. rather returning id 7, 11, 26 return 7, 7, 7. please can explain why?

i have written following code in .php file:

session_start(); if (isset($_post['newsearch']) === true && empty($_post['newsearch'] === false)){ require 'dbconnect.php'; $term = $_post['newsearch']; $terms = "%" . $term . "%";  $query = ("select playerid players username '$terms'"); $run_query = mysqli_query($dbcon, $query); $search = mysqli_fetch_assoc($run_query); $players = array ();      do{     //get data players table     $playerid = $search['playerid']; array_push ($players, $playerid);             }         while ($dbsearch = mysqli_fetch_assoc($run_query));} 

you have more 1 fetch same query, replace code after $run_query = mysqli_query($dbcon, $query); code:

 $players = array ();  while ($dbsearch = mysqli_fetch_assoc($run_query))      {          array_push($players, $dbsearch['playerid']);;      }
