What is Localhost?

open   http://localhost/ ➚

"localhost" is a networking term that refers to the current device or system being used to access it. It is a loopback mechanism that allows a computer to connect to itself as a server or a client, primarily for testing, debugging, and development purposes.

In technical terms, localhost is associated with the IP address for IPv4 or ::1 for IPv6. These IP addresses are reserved for loopback connections, which are network connections made within a single device. When a user accesses a service on their own device using localhost or the associated IP addresses, they are effectively connecting to a server or service running on their own computer.

Localhost is commonly used by developers to test web applications, APIs, and other network services before deploying them on a remote server or production environment. By running the service on their own system and accessing it via localhost, developers can ensure the proper functionality, performance, and security of their applications without exposing them to external networks or users.

In summary, localhost is a self-referential hostname that enables a computer to connect to itself as a server or client. This mechanism facilitates the testing and development of network services and applications within a local environment before deployment in a production setting.

How to login http://localhost/ server?

To access a local server running on your machine via http://localhost/, you need to have a web server installed and running on your computer. Popular web server packages include XAMPP, WAMP (for Windows), MAMP (for Mac), and LAMP (for Linux). These packages come with Apache, MySQL/MariaDB, and PHP pre-configured, making it easy to set up a local web server environment.

Once you have a web server installed and running, follow these steps:

  1. Place your web project files in the appropriate directory of your web server:

    • For XAMPP, place your files in the "htdocs" folder (e.g., C:\xampp\htdocs\ on Windows).
    • For WAMP, place your files in the "www" folder (e.g., C:\wamp\www\ on Windows).
    • For MAMP, place your files in the "htdocs" folder (e.g., /Applications/MAMP/htdocs/ on macOS).
    • For LAMP, place your files in the "html" or "htdocs" folder (e.g., /var/www/html/ on Linux).
  2. Start your web server software:

    • For XAMPP, open the XAMPP Control Panel, and start the "Apache" and "MySQL" services.
    • For WAMP, start the WampServer application and ensure the "Apache" and "MySQL" services are running.
    • For MAMP, open the MAMP application and click "Start Servers."
    • For LAMP, start the Apache and MySQL/MariaDB services using your system's service management commands (e.g., sudo systemctl start apache2 and sudo systemctl start mysql on Debian-based Linux distributions).
  3. Open a web browser and navigate to http://localhost/ or You should see the default web page for your web server or your project's index file, depending on your configuration.

If you have set up a local server for a specific application like phpMyAdmin or a custom project, you can access it by appending the folder name or alias to the URL, such as localhost/phpmyadmin or http://localhost/your_project_folder.

Keep in mind that if you are using a custom port number for your web server, you will need to include it in the URL, such as localhost:8080.

Credit card payment back-end development on localhost

You can simulate and test your software like a real payment transaction by creating a virtual credit card payment system on localhost. As an example, Paytr virtual pos integration with PHP has been added in the code below. Another method is to use an external credit card generator app. You can customize it for yourself. The required parameters are sent to paytr, and it opens a payment screen in an iframe. You are creating a notification_url page in Paytr settings.

Order confirmation or cancellation is made on that page. A hash is generated with the incoming credit card post values, and if the hash value from the post is not equal, a bad hash error occurs. If it is, the process continues. If it is successful, the db queries are made. If it is successful, it goes to the specified payment_payment_failure.php page I used the pdo library in the .notification url page.

$oid = rand(1.99999);
$merchant_id = 'merchcantid';
$merchant_key = 'merchant key';
$merchant_salt = 'saltkey';
$email = 'email';
$payment_amount = '999'; // For 9.99, 9.99 * 100 = 999 should be sent.
$merchant_oid = $oid; // different id for each request
$user_name = 'address line';
$user_address = 'address';
$user_phone = 'phone';
$merchant_ok_url = 'odeme_basarili.php'; // if the payment is successful
$merchant_fail_url = 'payment_fail.php''; // the page to return if the payment is unsuccessful
 $user_basket = base64_encode(json_encode(array(
        array('product name' , '9.90', '3'), // 1st item (Product Name - Unit Price - Quantity ) ));
if( isset( $_SERVER["HTTP_CLIENT_IP"] ) ) {
        $ip = $_SERVER["HTTP_CLIENT_IP"];
    } elseif( isset( $_SERVER["HTTP_X_FORWARDED_FOR"] ) ) {
        $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
    } else {
        $ip = $_SERVER["REMOTE_ADDR"]; }
 $user_ip = $ip;
$timeout_limit = "30";
$debug_on = 1; // debug mode
$test_mode = 0; // 1 for test mode
$no_installment = 0; // 0 if no installment
$max_installment = 0;

How can I hosting on my pc?

Local hosting is closed on normal computers, so some programs need to be installed to get server properties in order to broadcast it. It is very easy to do this because the server operating systems are ready for it, but in end-user operating systems this is a bit tricky. Some software can do this easily, so let's have a look at them.

Which software will enable our computer's localhost? What software does the localhost wiki activate?

The programs mentioned above activate localed hosts of your computer. Php and Mysql are installed and your computer is ready to broadcast. It is for you to run the dynamic web pages of PHP, MySQL and PhpMyAdmin. While we can run static html or php pages on http://localhost/ without needing anything, we can not run dynamic web pages with php script like this.

Can anyone access from us?

We can answer this in the form of yes and no. Let me explain that nobody can see an internet site you posted on l.h., but if you set your modem's external ip to static ip and set external requests to redirect to local-host, you can open your site on your personel computer in the outside world.
