无法用htaccess在php文件中打开类php

Question

I want to include a class that has been made ​​to the php file, here I am using .htaccess. but once put into a php file, the php class can not be opened or loaded in a php file. The following directory structure in my web.

htdocs/
       mysite/
              src/
                     App/
                     Login.php <-- class file php
              public/
                     login.php <-- file php

this is login class (mysite/src/App/Login.php)

class Login {

     private $username;
     //etc...

} 

this is login file (mysite/public/login.php)

require('../src/App/Login.php');

$login = new Login();

this is .htaccess file (mysite/.htaccess)

Options +FollowSymLinks
RewriteEngine On

# skip for existing files/directories (/assets will be skipped here)
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]

# for public directory
rewritecond %{REQUEST_URI} !^/public/(.*)
RewriteRule .* index.php [L]

and index.php for rule in .htaccess file (mysite/index.php)

$requested = empty($_SERVER['REQUEST_URI']) ? false : $_SERVER['REQUEST_URI'];
$server_name = str_replace(basename($_SERVER['SCRIPT_NAME']), "", $_SERVER['SCRIPT_NAME']);

switch ($requested) {

    case $server_name:
        include 'public/index.php';
        break;
    case $server_name.'login':
        include 'public/login.php';
        break;
    default:
        include 'public/404.php';
}

but when I open localhost/mysite/login there is an error

Warning: require(../src/App/Login.php): failed to open stream: No such file or directory in C:\xampp\htdocs\mysite\public\login.php on line ...

Fatal error: require(): Failed opening required '../src/App/Login.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\mysite\public\login.php on line ...

Can you help me?

thank you

A simple rule for including files via a relative path where you have not configured an application level include_path; always base the relative path from that of the current script, eg

// public/login.php

require_once __DIR__ . '/../src/App/Login.php';

Because you're including public/login.php from index.php, the include path includes the parent directory of index.php, ie mysite. This applies across any files included.

When public/login.php tries to include ../src/App/Login.php it is actually attempting to open htdocs/mysite/../src/App/Login.php.

Another thing you might want to try is configure an application level include path. For example, in index.php...

set_include_path(implode(PATH_SEPARATOR, [
    __DIR__ . '/src/App',
    get_include_path()
]));

Now your src/App directory is the first searched when performing an include or require so you can simply run

require_once 'Login.php';

Update

An even better solution would be to register an autoloader, for example (in index.php)

spl_autoload_register(function($class) {
    require_once sprintf('%s/src/App/%s.php', __DIR__, $class);
});

Then you can simple create your class without worrying about including the file...

$login = new Login();
