[SOLVED] Unable to connect to the database

Did you try the config database settings alone to see if they work?
Also the base_url in your env.txt should have an ending backslash on it \

You can try this to see if you can connect stand alone.

PHP Code:

<?php
// Code to create the database

// Add your own username and password
$serverName = "localhost";
$userName   = "username";
$password   = "password";

// Create the Database Connection
$connId = mysqli_connect($serverName, $userName, $password);

// Check the Database Connection
if ($connId === false)
{
    exit("ERROR: Could not connect. " . mysqli_connect_error());
} 

// Create the Database
// Add your datya
$sql = "CREATE DATABASE yourDatabaseName";

// Check that the Database was created
if (mysqli_query($connId, $sql))
{
    echo "Database created successfully";
}
else
{
    echo "ERROR: Creating Database. " . mysqli_error($connId);
}

// Close the Connection
mysqli_close($connId);

?>

i Change your code :

PHP Code:

<?php
// Code to create the database

// Add your own username and password
$serverName = "localhost";
$userName   = "xxxx";
$password   = "xxxx";

// Create the Database Connection
$connId = mysqli_connect($serverName, $userName, $password);

// Check the Database Connection
if ($connId === false)
{
    exit("ERROR: Could not connect. " . mysqli_connect_error());
} 

// Create the Database
// Add your datya
$sql = "select * from xxxx.admin";

// Check that the Database was created
if (mysqli_query($connId, $sql))
{
    echo "Database created successfully";
}
else
{
    echo "ERROR: Creating Database. " . mysqli_error($connId);
}

// Close the Connection
mysqli_close($connId);

?>

and result is : Database created successfully
