Is it necessary to configure .htaccess files in subdirectories for PHP file uploads, or is the root directory sufficient?

When allowing file uploads in PHP, it is necessary to configure the .htaccess file to set specific directives such as upload_max_filesize and post_max_size. These directives control the maximum size of files that can be uploaded to the server. It is recommended to configure the .htaccess file in both the root directory and any subdirectories where file uploads are allowed to ensure that the settings apply to all relevant locations. 

# .htaccess file in root directory
php_value upload_max_filesize 20M
php_value post_max_size 20M

# .htaccess file in subdirectory
php_value upload_max_filesize 20M
php_value post_max_size 20M
