Mysqli_connect create error 500

Hey! I get HTTP error 500 everytime I try to use mysqli_connect in my php file.

This is my code and link to the file I am having trouble with: http://138.68.86.134/getInfo.php

<?php
  session_start();

  if(!isset($_SESSION["access"])) {
    echo "null";
  } else if (isset($_SESSION["access"])) {
   // Here I am trying to use mysqli_connect
    $db = mysqli_connect("138.68.86.134", "root", "mypassword", "database")
    echo "Confirmed";
  } else {
    echo "Something went wrong...";
  }

 ?>

This is my Info.php file: http://138.68.86.134/info.php

I’ve followed every step for Debain LAMP tutorial here on DigitalOcean still this doesn’t work. I am very frustrated and I would highly appreciate any answer! Much love <3

Try this quick solution and if it works I will explain it to you.

Replace 138.68.86.134 with 127.0.0.1 and try again.

Before we get to troubleshooting, I would highly recommend and encourage you to use a created user instead of root. Should someone find a way in to your application, root access grants them the ability to remove everything (including other databases). You should never run as root :-).

…

That said, you’re missing a ; at the end of the function call for mysqli_connect().

i.e. This line:

$db = mysqli_connect("138.68.86.134", "root", "mypassword", "database")

Should be:

$db = mysqli_connect("138.68.86.134", "root", "mypassword", "database");
