通过简单函数实现HTML的过程化生成。在PHP中

echo "<p>This is a paragraph.</p>";

$title = "Welcome to my website";
echo "<h1>" . $title . "</h1>";

function generateButton($text, $url) {
    $button = "<a href='" . $url . "'>";
    $button .= "<button>" . $text . "</button>";
    $button .= "</a>";
    return $button;
}

// 调用函数生成一个按钮
echo generateButton("Click me", "https://www.example.com");
