mysqli_query(): Couldn't fetch mysqli error

Question

I am receiving a \"Couldn\'t fetch mysqli\" error on the following function when trying to import data from a text file. However the insert function is working just fine in

Answer 1

I suspect you're calling the function multiple times. But it calls mysqli_close($conn) at the end, so when you try to use it the next time you get an error, because $conn can't be used any more.

Get rid of that line, and close the connection when the script is all done using MySQL (or don't bother, it will be closed automatically when the script ends).
