How to access database connection and base url in child folder? - php

Question

I am working on XYZ project. In that project having admin, assets, class, controller, core folder and some .php files. In core folder having config.php and database.php files.
Here's config.php code:
<?php
include ("core/database.php");
spl_autoload_register(function ($class_name) {
include ('class/'.$class_name . '.php');
});
?>
and database.php code:
<?php
session_start();
define('BASE_URL', 'http://localhost/XYZ/');
class database{
private $servername;
private $username;
private $password;
private $dbname;
protected function connect(){
$this->servername = 'localhost';
$this->username = 'root';
$this->password = '';
$this->dbname = 'xyz';
$conn = new mysqli($this->servername, $this->username, $this->password, $this->dbname);
return $conn;
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
}
}
?>
Here's index.php code:
<?php
include("core/config.php");
echo BASE_URL;
exit();
?>
In that page i got BASE_URL in defined in database.php
But when i try to get same BASE_URL in admin->index.php got some error following:
Warning: include(core/database.php): failed to open stream: No such file or directory in C:\xampp\htdocs\xyz\core\config.php on line 3
Warning: include(): Failed opening 'core/database.php' for inclusion (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\xyz\core\config.php on line 3
Notice: Use of undefined constant BASE_URL - assumed 'BASE_URL' in C:\xampp\htdocs\xyz\admin\index.php on line 3

So, My query is how to access databse connection and BASE_URL in admin->index.php
#rajeev answer i got database connection and BASE_URL in admin->index.php
But i have one more query
In class folder having Test.php file the code is below:
<?php
class Test extends Database{
function __construct(){
date_default_timezone_set('Asia/Kolkata');
$date = date("y-m-d H:i:s");
$this->get_date = $date;
}

and i tried code in admin->index.php
<?php
include("../core/config.php");
$testClass = new Test();
echo $testClass->test();
?>

You can use "getcwd"(https://www.php.net/manual/en/function.getcwd.php) function to gets the current working directory. If the "class" folder isn't accessible in the current working directory, you will have to change your include path in the "config.php" file.
