Number format for wp_count_posts()

I’m trying to format my post my total post count in the header of my site. I have the number in there but would like it to format with the commas eg 1,500 not 1500. I know this is probably really basic but I’m still learning.. any help would be much appreciated. Cheers

functions.php

function wpb_total_posts() { 
$total = wp_count_posts()->publish;
echo '' . $total;
}

Header.php

<?php wpb_total_posts(); ?>

Method 1

You can use the PHP function number_format().

function wpb_total_posts() { 
    $total = wp_count_posts()->publish;
    echo number_format( 
        $total, // your number
        0,      // number of decimal points
        '.',    // decimal point separator
        ','     // thousands separator
    );
}

Or, because you are using the default values anyway, you can shorten the function to:

function wpb_total_posts() { 
    echo number_format( wp_count_posts()->publish );
}
