How to write if else statement in a single line (compact if else statement) using PHP

Normal way of writing an if else statement

<?php

$result = '';

$count = 55;
$target = 70;

if($count >= $target) {
   $result = 'High';
} else {
   $result = 'Low';
}

?>

$result = ($count > $target) ? 'High' : 'Low';

How to programmatically add a WordPress admin user using functions.php

Step 1:
Open your theme’s functions.php using a editor.

Step 2:
Paste the following code at the bottom of the functions.php (need to remove once the user is added)

add_action('init', 'create_my_custom_admin_user');

function create_my_custom_admin_user() {
    $username = 'username123';
    $password = 'pasword123';
    $email = 'newadmin@example.com';

    if (username_exists($username) == null && email_exists($email) == false) {

        // Create the new user
        $user_id = wp_create_user($username, $password, $email);

        // Get current user object
        $user = get_user_by('id', $user_id);

        // Remove role
        $user->remove_role('subscriber');

        // Add role
        $user->add_role('administrator');
    }
}

Step 3:
Save the functions.php file and run the site once.

Step 4:
Go to the site’s login page (wp-login.php) and login with the username and password that are used on the functions.php. You should be able to login and see the dashboard.

Note: If the username or email already exists in the dashboard, you will not be able to login and in that case you may have to username and/or password.

Step 5:
Please remove the code block and save the functions.php once the user is added.

How to get current page full URL in PHP

Step 1: Deciding on the SSL protocol whether the site using http or https.

if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on') {
   $url = 'https';
} else {
   $url = 'http';
}

Step 2: Append domain name or IP to the URL

$url .= $_SERVER['HTTP_HOST'];

Step 3: Append the current page URL after domain / IP

$url .= $_SERVER[‘REQUEST_URI’]

Step 4: Let’s put all these together and create a function that can be reused.

function getfullpageurl() {
    if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on')   
         $url = "https://";   
    else  
         $url = "http://";   
       
    $url.= $_SERVER['HTTP_HOST'];   
    
    $url.= $_SERVER['REQUEST_URI'];    
      
    return $url;  
}
