用成千上万的数字格式化数字 [英] Format a number with grouped thousands

问题描述

我具有以下功能:

function getPostViews($postID){
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return __('0 View','mm');
    }
    return $count. __(' Views','mm'); 
}

我如何使其格式化数字以在千位中包含逗号?例如，50000应该变成50,000.

How do I make it format a number to include a comma in the thousandths place? For example, 50000 should become 50,000.

推荐答案

使用 number_format() :

number_format($number);
