Detect when the reader is in a mobile device – WordPress

In WordPress, wp_is_mobile() is a function that is used to determine whether the current user agent (web browser) is accessing the site using a mobile device. This function checks if the user is browsing the site from a mobile device and returns a boolean value accordingly.

Here’s an example of how you might use wp_is_mobile() in a WordPress theme or plugin:

if ( wp_is_mobile() ) {
    // Code to execute if the user is on a mobile device
    echo 'This is a mobile device!';
} else {
    // Code to execute if the user is not on a mobile device
    echo 'This is not a mobile device!';
}

This can be useful if you want to provide a different user experience or display different content based on whether the user is using a mobile device or not. Keep in mind that user agent detection may not be 100% accurate, and it’s generally recommended to use responsive design techniques (like CSS media queries) to create a mobile-friendly layout instead of relying solely on user agent checks.
