php - 将逗号放在 PHP 数字变量中

Question

我在我的 header.php 中使用一个脚本来显示注册的用户数量(例如，它显示 79447 个玩家)，但我希望它显示 79,447 个玩家。我将如何添加逗号？我尝试了几种方法但都失败了。

<?php
include('session.php');
?>

<style>
.navbar {
    font-family: 'Numans', sans-serif;
    text-transform: uppercase;
}
.navbar-inverse {
    background: #00aa00;
}
.dropdown-menu li a:hover, .dropdown-menu-default li a:hover {
    color: #00aa00;
}
.dropdown-menu {
min-width: 100%;
border-radius: 0px;
}
.navbar .navbar-form .form-control-wrapper .form-control, .navbar .navbar-form .form-control {
    text-transform: uppercase;

    margin-right: 4px;
}

从代码片段来看，用户数量似乎在变量 $remote_job->amount 中

echo number_format($remote_job->amount);
