include vendor/autoload.php automatically

If we want to use composer packages, we have to include 'vendor/autoload.php', and if we don't have a front controller design pattern, we must include 'vendor/autoload.php' on every/most files. Why not to auto include 'vendor/autoload.php' file (if vendor folder exists)? * PHP will use include_once to include file Example Directory Structure: - Index.php (file) - Test.php (file) - Classes (folder) -- Classes/test2.php (file) - Vendor (folder) - On Index.php, php will automatically include 'vendor/autoload.php' because the vendor directory exists. - On Test.php, php will automatically include 'vendor/autoload.php' because the vendor directory exists. - On Classes/test2.php, since file is in sub directory and here vendor directory doesn't exist, so php will not include 'vendor/autoload.php'
