How to detect if mod_rewrite is available?

问题

Good day. I have a problem with links in my application. I want to use 'pretty-urls',so i want to all my links look like 'www.sitename.com/controller/method'. So i want to print my all my links through one function,which would look like

function link($url_segments) {
  if(mod_rewrite_is_available) 
     return BASE_URL.$url_segments;
  else
     return BASE_URL."index.php".$url_segments;
}

But i can't understand how to detect if server has rewrite module enabled. I have found 2 solutions:

Place in config some variable(like codeigniter does) like $config["index_variable"] to use inside my function,but that means that all my clients will need to change that line in config when installing application on hosting
Use function to detect mod_rewrite,like apache_get_modules,but like i understood it can be not avaibale on some hosting,and what if server will be nginx?

So i want to know,how to detect that and print my links.

Thanks everyone for help.

回答1:

Can you just provide the .htaccess to your clients so that, when you upload the files, it turns the rewrite mod on?

回答2:

This can be very tricky and hard, personally, I would go with the fallback approach.

Look at apache2handler's loaded modules (via phpinfo()) to see if mod_rewrite is there
Try sudo apache2ctl -t -D DUMP_MODULES to see if mod_rewrite is loaded
Try to use a .htaccess file to see if everything is working.
Try to determine the server software used, and parse the conf file for the server
Use worst case of no mod_rewrite is enabled, and then enable it manually after the software has been installed.
