Apache is one powerfull web server most used on cyber world. So many module to configuring as you want. One of them called mod_php. Sometimes we need different value of php main configuration. An example, on php main configuration we’ve added upload max 5M. So, you want a directory have different to upload more 5 M, example: 100M. So just add to your own directory directive:

<Directory /usr/local/www/upload>
php_value upload_max_filesize 100M
php_value post_max_size 100M
php_value max_execution_time 200
php_value max_input_time 200
</Directory>

semoga membantu.. :)
