Call to a member function bind_param() on a non-object [duplicate]

Answer 1

i'm using the mysqli approach as well and got the same error when I created another instance of mysqli before closing the first instance. So its important to use close() before starting the same piece of code. For example:

$DBH = getDBH();
$qSelect = $DBH->prepare("SELECT * FROM users WHERE username = ?");
$qSelect->bind_param("s", $username);
$qSelect->close();  // <--- use close before calling the same function( wich contains $DBH code) again;
