Answer 1

if you want to prevent error from being shown just put this line on top level of your code:

error_reporting(~E_ALL);

Answer 2

try this on your local but not in sololearn playground:

<?php

$db = [];
$db['db_host'] = 'localhost';
$db['db_user'] = 'root';
$db['db_pass'] = '';
$db['db_name'] = 'cms';

foreach ($db as $key => $values){
define(strtoupper($key), $values);
}

$connection = mysqli_connect( DB_HOST, DB_USER, DB_PASS, DB_NAME );

if($connection ){
echo "connected";
}
?>

Answer 3

What is wrong on mine...just the empty declaration of db 😕??

Answer 4

you're not explicitly declared "$db" variable

Answer 5

But why it is then shows connected on my local texteditor

Answer 6

you're not getting any kind of errors ?

Answer 7

"Notice undefined variable db and so so."...and then at last shows me connected

Answer 8

Actually i am using the post method to display dynamically on my browser...but due to that notice error on connection time i am misleading...

Answer 9

and the reason why it's always show connected because mysqli_connect function always return an object of type mysqli:
