php获取网站基础路径baseUrl的两种方法

方法一:

// baseUrl
function baseUrl($uri=''){
	$baseUrl = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') ? 'https://' : 'http://';
	$baseUrl .= isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : getenv('HTTP_HOST');
	$baseUrl .= isset($_SERVER['SCRIPT_NAME']) ? dirname($_SERVER['SCRIPT_NAME']) : dirname(getenv('SCRIPT_NAME'));
	return $baseUrl.'/'.$uri;
}

方法二:

/**
     * Suppose, you are browsing in your localhost
     * http://localhost/myproject/index.php?id=8
     */
    function baseUrl()
    {
        // output: /myproject/index.php
        $currentPath = $_SERVER['PHP_SELF'];

        // output: Array ( [dirname] => /myproject [basename] => index.php [extension] => php [filename] => index )
        $pathInfo = pathinfo($currentPath);

        // output: localhost
        $hostName = $_SERVER['HTTP_HOST'];

        // output: http://
        $protocol = strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https://' ? 'https://' : 'http://';

        // return: http://localhost/myproject/
        return $protocol.$hostName.$pathInfo['dirname']."/";
    }
