卓越飞翔博客php小编柚子为您介绍如何在php中设置php_auth_user和php_auth_pw，这两个变量是用于http基本认证的用户名和密码，可用于验证用户身份。通过设置这两个变量，您可以在php脚本中轻松获取用户提供的用户名和密码信息，从而实现安全的身份验证功能。本文将详细讲解如何在php代码中设置和获取这两个变量，让您轻松应对身份验证需求。
在 PHP 中使用 curl Post 请求设置 PHP_AUTH_USER 和 PHP_AUTH_PW
我们将通过向 PHP 代码发送 curl 请求来设置用户名和密码。

</span></span>在 PHP 中在命令行中使用 curl 请求设置 PHP_AUTH_USER 和 PHP_AUTH_PW
我们将通过命令行发送 curl 请求来设置用户名和密码。
<code class="language-shell hljs" data-lang="shell"><span style="display:flex;"><span>curl --user Kevin:Musungu455 http://localhost:2145
</span></span>在 PHP 中如何确认值 PHP_AUTH_USER 和 PHP_AUTH_PW 是否已成功设置
我们将检查用户名和密码是否已设置，如果已设置，则显示带有用户名和密码的成功消息。
