Use the autoloader, but it is best to use composer, after all, convenient
Https://github.com/WhichBrows ...

function InstallComposer(){    file_put_contents(__DIR__ . '/composer-setup.php', file_get_contents('https://getcomposer.org/installer'));    shell_exec('php composer-setup.php');}function InstallParser(){    shell_exec('php composer.phar require whichbrowser/parser');}

1. If not used Composer : If the file is less direct, require come in good, if the file involved more, look at the Library namespace usage specification is Psr4 still Psr0 , write a autoload method, automatic introduction of files, can be referenced Composer ClassLoader .

2. If used Composer , write one directly composer.json and put the required library into require .

   #composer.json"require": {    "php": ">=5.3.3",    "godtail/db": "dev-master" #例子}#然后composer install`#引入autoload文件require '../vendor/autoload.php';

Of course, the recommended use of composer, modular, more convenient.

Install parser First
And then in the file

require 'vendor/autoload.php';

That's it.
