Question: Closing mysqli connection

[Jolo Balbin]

function pathFind(/*parameters*/)
{
  $db = new DB();
  $dbq = $db->DBcon();

  // query here.

  $stmt = $dbq->prepare($query);
  $stmt->bind_param(/*parameters*/);
  $stmt->execute();
  $stmt->bind_result(/*parameters*/);

  while($stmt->fetch())
  {
    pathFind(/*variables*/); <----- recursion here.
  }
} 

So here. Do I still need to close my connections even PHP can do it for me? I'm just worried that I exceed the connection limit because my function is in recursion.

And when I attempt to close, I receive a warning: Couldn't fetch mysqli.

[YowMamaSita]

when the interpreter finishes reading the a php file, all connections made are automatically closed. pero in cases na this is used inside recursions, until matapos yung recursion, di siya magcloclose so its best if you do close it before the function ends

with the warning, try replacing mysqli:// with mysql:// or kung wala kang ganyang strings, it has something to do with your settings on how php connects to mysql
