Couldn't fetch Mysqli_result

Question

I\'ve got this error

Warning: mysqli_fetch_array() [function.mysqli-fetch-array]: Couldn\'t fetch mysqli_result in /home/fights7/public_html/i

Answer 1

Straight away, it appears that you are calling mysqli_free_result() inside your fetch loop, so after the first loop iteration, your result resource has been closed and freed, and no more results will be available.

while($articles_info = mysqli_fetch_array($articles_data)) {
  $json = array();
  $json['streamitem_id'] = $articles_info['streamitem_id'];
  $json['streamitem_content'] = $articles_info['streamitem_content'];
  $json['streamitem_timestamp'] = $articles_info['streamitem_timestamp'];
  // Don't do this!
  //mysqli_free_result($articles_data);
}
// If you need to, free it outside the loop
mysqli_free_result($articles_data);

I note that you're calling mysqli_fetch_array() without specifying MYSQLI_ASSOC, and so you're getting both numeric and associative keys back. If you are using everything in your JSON, you don't need to do all those assignments if you use MYSQLI_ASSOC or mysqli_fetch_assoc():

while($articles_info = mysqli_fetch_assoc($articles_data)) {
  // No need for the $json array. Just use $articles_info directly
  // if you were going to json_encode() it.
}
