php - Fetch array returns only one row - 


<?php  function comment($postid,$db_con) {  $commentdiv='';  $sql="select userid,time,comment comments postid='$postid' limit 3";  $query = mysqli_query($db_con, $sql);  while($row = mysqli_fetch_array($query,mysqli_assoc)){     $uid=$row["userid"];     $timecomment=$row["time"];     $comment=$row["comment"]; $sql="select username,photo users id='$uid'"; $query = mysqli_query($db_conx, $sql);  $row = mysqli_fetch_array($query,mysqli_assoc);  $username=$row["username"];  $photo=$row["photo"];  $userphoto='<img src="xxx/'.$username.'/'.$photo.'">';  if($photo== null){      $userphoto = '<img src="xxx/default.png">';  }  $commentdiv.='<div class="xxxxxxx"><div class="yyyyyy">'.$userphoto.'</div><div class="zzzzz">'.$username.'</div><div class="vvvvv">'.$comment.'</div></div>'; } return $commentdiv; } ?>

i new php, trying return 3 comments above php code, above code returns 1 row database, why fetch array return 1 row when there more 1 row?

try,i use $query2 = mysqli_query($db_conx, $sql); second query,because reset first loop

 <?php  function comment($postid,$db_con)  {  $commentdiv='';  $sql="select userid,time,comment comments postid='$postid' limit 3";  $query = mysqli_query($db_con, $sql);    while($row = mysqli_fetch_array($query,mysqli_assoc)){   $uid=$row["userid"];   $timecomment=$row["time"];   $comment=$row["comment"];   $sql="select username,photo users id='$uid'";   $query2 = mysqli_query($db_conx, $sql);  // added new variable   $row = mysqli_fetch_array($query2,mysqli_assoc);   $username=$row["username"];   $photo=$row["photo"];   $userphoto='<img src="xxx/'.$username.'/'.$photo.'">';  if($photo== null){     $userphoto = '<img src="xxx/default.png">';   }      $commentdiv.='<div class="xxxxxxx"><div class="yyyyyy">'.$userphoto.'</div><div         class="zzzzz">'.$username.'</div><div class="vvvvv">'.$comment.'</div></div>';  }  return $commentdiv; } ?>
