为什么wp_head将我的函数挂接到源代码的开头?

为什么wp\\u head会将我的函数挂接到源代码的开头,尽管“wp\\u head”出现在我的代码中标记的前面。

下面是源代码

<php?
    function load_css()
{
  wp_register_style(\'bootstrap\', get_template_directory_uri() . \'/css/bootstrap.min.css\', array(), false, \'all\' );
  wp_enqueue_style(\'bootstrap\');

wp_register_style(\'main\', get_stylesheet_directory_uri() . \'/css/main.css\', array(), false, \'all\' );
wp_enqueue_style(\'main\');
}

add_action(\'wp_enqueue_scripts\', \'load_css\');


    function load_js()
{
wp_enqueue_script(\'jquery\');

wp_register_script(\'bootstrap\', get_template_directory_uri() . \'/js/bootstrap.min.js\', \'jquery\', false, true,);
wp_enqueue_script(\'bootstrap\');
}
add_action(\'wp_enqueue_scripts\', \'load_js\');

?>

这是我的标题。php看起来像

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <?php wp_head();?>
  </head>

事实并非如此。您编写的PHP标记不正确,因此您的代码将被打印到浏览器中,而不是运行。你有<php?. 应该是这样的<?php.
