php拼接域名

<?php
$protocol = "https://";
$host = "example.com";
$path = "/api/v1/data";
$query = "?id=123";

// 拼接完整的URL
$url = $protocol . $host . $path . $query;

echo $url; // 输出: https://example.com/api/v1/data?id=123
?>

<?php
$protocol = "https://";
$host = "example.com";
$path = "/api/v1/data";
$query = "?id=123";

// 去除空格并拼接完整的URL
$url = trim($protocol) . trim($host) . trim($path) . trim($query);

echo $url; // 输出: https://example.com/api/v1/data?id=123
?>

<?php
$protocol = "https://";
$host = "例子.测试"; // 假设这是从数据库或配置文件中读取的域名
$path = "/api/v1/data";
$query = "?id=123";

// 确保所有字符串使用相同的编码
$host = mb_convert_encoding($host, 'UTF-8', 'auto');

// 拼接完整的URL
$url = $protocol . $host . $path . $query;

echo $url; // 输出: https://例子.测试/api/v1/data?id=123
?>
