Google Pixel 6 and Google Pixel 6 Pro leaked with some designs. Both devices appear to have a single-hole punched display and a bold industrial design on the back. Both devices appear to have a camera on their back that is a kind of bridge from one side to the other.

For your information, The leaks aren’t straight-up leaked from Google or anything like that, but were created by a third party based on real-life images of the phones.

The Google Pixel 6 Pro appears in this leak in two color combinations. Instead of a white background rear section, this larger Pixel 6 Pro appears with a very light orange background section. The Google Pixel 6 Pro also appears in a color scheme with an off-white bottom and champagne accents.

The Pixel 6 looks smaller and has only two cameras on the back, we wouldn’t be surprised if one of them was a normal wide sensor while the other was an ultra-wide. The Pixel 6 Pro, on the other hand, appears larger and adds a third sensor, hopefully a telephoto lens, though from the looks of these renders it won’t be a periscope type, so can’t expect more than 3x optical magnification.

Hopefully Google will also update the sensors it uses, which are getting kind of old now.

There are several ways to add a basic authentication using php. Today I would like to share a snippet to add basic authentication easily.

Lets get started.

<?php

//you can define your custom username and password here.
$AUTH_USER = 'username';
$AUTH_PASS = 'password';

header('Cache-Control: no-cache, must-revalidate, max-age=0');
$credentials = !(empty($_SERVER['PHP_AUTH_USER']) && empty($_SERVER['PHP_AUTH_PW']));

//check credentials existence or wrong credentials
$auth_fail = (
	!$credentials ||
	$_SERVER['PHP_AUTH_USER'] != $AUTH_USER ||
	$_SERVER['PHP_AUTH_PW']   != $AUTH_PASS
);

//Ask for the auth. If credentials are not correct, deny the access.
if ($auth_fail) {
	header('HTTP/1.1 401 Authorization Required');
	header('WWW-Authenticate: Basic realm="Access denied"');
	exit;
}

After the coding process, you will get a confirmation alert box for authentication before accessing the website as below.

Well, I think you can now add basic auth in any of your PHP application neat and easily.

If you want to add basic authentication for contents like html and images etc , you can also do that by configuring .htaccess
